Storage that goes to the work
The best tool carts, and the rating almost none of them split by shelf
Every cart here publishes a total capacity. One publishes what a single shelf holds, one publishes its steel, and one publishes how deep its trays are. Those three numbers decide a cart, and here is who prints them.
For a steel cart, the Sunex 8005SC - the only one here that publishes its steel, at 16 gauge, with 350 lb capacity and two locking casters. For a plastic cart, the WEN 73009 - the only one that publishes a per-shelf rating (250 lb each), on the largest casters here at 5 in. If loose parts roll off your current cart, the WEN 73163 publishes the deepest trays at 3.75 in.
A cart is not a small tool box
A tool box stores tools. A cart carries them to the work and holds them there while you use them - beside the wheel you have off, under the bench you are assembling on, next to the machine you are servicing. That difference changes which numbers matter.
On a tool chest the governing figures are body gauge and drawer slide rating, because the question is what the box will hold for a decade. On a cart the questions are what one shelf will carry, whether things stay on it while it moves, and whether it rolls over the floor you actually have. Rolling tool boxes covers the storage side of anything with wheels; this page is about the thing you push.

2 · The highest steel-cart capacity, and it takes magnets
GEARWRENCH 36 in. 2-Shelf Steel Automotive Utility Cart (GWMSC)
The highest published capacity of the steel carts here at 440 lb, on a 36 x 16 in footprint that weighs a published 29.1 lb empty. Barrier walls keep things on the shelves and the steel takes a magnetic tray - the thing a plastic cart can never do.
- Body steel
- Not published
- Per drawer
- Not published
- Storage
- Not published
- Empty weight
- 29.1 lb7 lb per caster, empty
What works
- 440 lb is the highest published capacity of any steel cart on this page
- Publishes an empty weight, so you know what you are lifting into a truck
- Steel takes magnetic trays and bars, which is how a mechanics cart keeps sockets from rolling
- Barrier walls on the shelves rather than a flat edge
What does not
- No published gauge, so the 440 lb rests on steel of unknown thickness
- 33 in tall is lower than the Sunex, which means more stooping at the top tray
- Hard polypropylene casters rather than a non-marring tread, which matters on a coated floor
- GEARWRENCH does not say how many of the casters lock
| Published specification | |
|---|---|
| Capacity | 440 lb total |
| Dimensions | 36 in x 16 in x 33 in, assembled |
| Empty weight | 29.1 lb |
| Shelves | Two, with barrier walls |

3 · The only cart that publishes what each shelf holds
WEN 73009 Two-Shelf Service Utility Cart, 500 lb
The one cart on this page that publishes a per-shelf capacity - 250 lb on each of two 30 x 15 x 3 in shelves, 500 lb total - and it rolls on the largest casters here at 5 in. It is polypropylene, so it will never rust or dent and it will never hold a magnet either.
- Body steel
- Not published
- Per drawer
- Not published
- Storage
- Not published
- Empty weight
- Not published
What works
- Publishes per-shelf capacity - the figure that actually matches how a cart gets loaded
- 5 in casters, the largest on this page, roll over cracks and cords that stop a 4 in caster
- Non-marring casters, so a coated floor survives it
- Polypropylene shrugs off brake fluid, coolant and water without rusting
What does not
- Two FIXED casters mean it steers like a shopping cart rather than turning in place
- No published brakes, so it rolls away on a sloped garage floor
- Plastic does not take magnets, so sockets and bits roll around the tray
- 3 in shelf lips are the shallowest published here
| Published specification | |
|---|---|
| Capacity | 250 lb per shelf, 500 lb total evenly distributed |
| Shelves | Two, 30 in x 15 in x 3 in |

Who it is for
A general garage cart that will meet fluids, and a floor that needs protecting.
What it is not for
A sloped floor, magnetic tool holding, or tight spaces that need four swivel casters.
4 · Three trays, with the deepest published lip
WEN 73163 Three-Tray Triple Decker Service and Utility Cart, 300 lb
Three trays instead of two, each 18 x 32 in with a published inner depth of 3.75 in - the deepest tray lip anyone publishes here, which is what stops a socket rolling off when the cart hits a crack. All four casters swivel and two have foot brakes. The trade is a 300 lb rating spread over three trays.
- Body steel
- Not published
- Per drawer
- Not published
- Storage
- Not published
- Empty weight
- Not published
What works
- 3.75 in inner tray depth, the deepest published lip on this page
- Four swivel casters, so it turns in place in a tight bay
- Two foot brakes, so it stays put on a sloped floor
- Three trays means the top one can be kept clear as a work surface
What does not
- 300 lb across three trays is the lowest capacity here, and WEN does not split it per tray
- 4 in casters stall on floor cracks and cords
- Aluminum and polypropylene do not take magnets
- No published overall height, so check it against your working height before buying
| Published specification | |
|---|---|
| Trays | Three, 18 in x 32 in |

| Per-tray capacity | Not published |
| Overall height | Not published |
| Where it is sold | Amazon, plus other retailers |
Who it is for
Loose small parts and hand tools that would roll off a shallow shelf.
What it is not for
Heavy parts, magnetic tool holding, or a cracked slab.
How we picked
- Total capacity, and whether it is split by shelf. A cart is never loaded evenly - the heavy part goes on one shelf. A published per-shelf figure matches how a cart is used; a total divided by the shelf count is a guess.
- Tray lip depth. The job of a cart is to move loose things. A shallow lip is how a socket ends up under the car when a caster hits a crack.
- Caster diameter, and how many swivel or brake. Bigger wheels roll over cords and slab joints. Four swivels turn in place; two fixed casters steer like a shopping cart. Brakes matter on a sloped garage floor.
- Steel or plastic. Steel takes magnetic trays and dents. Polypropylene never rusts and never holds a magnet. Neither is better; they suit different work.
- Is a gauge published? Steel carts almost never say how thick their steel is. The one that does has told you something the others chose not to.
What we did not do
Everyone in this category says they spent seventy-five hours testing tool chests. We have not opened any of these boxes, and we say so. What we do instead: compile the published specs, convert the steel gauges, multiply out the slide ratings, cite the maker’s own listing, and show the arithmetic so you can check it. The full method, including how to challenge a figure.
What each maker publishes
| Cart | Capacity | Per shelf | Tray lip | Casters | Material |
|---|---|---|---|---|---|
| Sunex 8005SC | 350 lb | Not published | Not published | 4 in, 2 lock + 2 swivel | 16 ga steel |
| GEARWRENCH GWMSC | 440 lb | Not published | Barrier walls, height not published | 4 in, locking | Steel, gauge not published |
| WEN 73009 | 500 lb | 250 lb each | 3 in | 5 in, 2 fixed + 2 swivel | Polypropylene |
| WEN 73163 | 300 lb | Not published | 3.75 in | 4 in, all swivel, 2 braked | Polypropylene on aluminum |
From each maker's own product page. 'Not published' means we checked that page and the figure is not there.
Read across the rows and each cart wins on exactly one disclosure. That is not a coincidence of this shortlist - it is how the category works. Makers publish the number they are proudest of, and nobody publishes all of them.
The per-shelf problem
Three of these four carts publish a total and stop. A total capacity is quoted for load evenly distributed across every shelf, and nobody loads a cart that way. The transmission you just pulled goes on the bottom shelf. The drill, the impact and their batteries go on the top one.
Dividing the total by the shelf count gives you a number that looks like a per-shelf rating and is not one. Whether a single shelf can carry half the cart's total depends on how that shelf is built and supported, and that is exactly the figure three of these four makers do not publish.
What we did with the totals
We quote each total as the maker publishes it and we do not divide it into a per-shelf number, because that would be inventing a specification. WEN publishes 250 lb per shelf on the 73009, so that figure appears. The other three show 'Not published', which is the honest answer.
16 gauge, converted
Sunex's 16-gauge figure is worth dwelling on, because it is thicker steel than any tool chest body on this site. Gauge numbers run backwards - lower is thicker - and the steps are uneven.
| Gauge | Inches | Millimeters | Vs 20 gauge | Where you see it |
|---|---|---|---|---|
| 14 ga | 0.0747 in | 1.90 mm | +108% thicker | Industrial and dealer-truck boxes |
| 16 ga | 0.0598 in | 1.52 mm | +67% thicker | Heavy professional cabinets |
| 17 ga | 0.0538 in | 1.37 mm | +50% thicker | Upper end of consumer heavy duty |
| 18 ga | 0.0478 in | 1.21 mm | +33% thicker | The thickest gauge mainstream brands publish |
| 19 ga | 0.0418 in | 1.06 mm | +16% thicker | Common on 56 in combo sets |
| 20 ga | 0.0359 in | 0.91 mm | reference | The default budget cabinet body |
| 21 ga | 0.0329 in | 0.84 mm | -8% thinner | Thin panels on light cabinets |
| 22 ga | 0.0299 in | 0.76 mm | -17% thinner | Portable boxes and drawer bottoms |
Thicknesses are the Manufacturers' Standard Gauge for sheet steel. The comparison column is computed against 20 gauge, the most common budget tool-box body.
At 0.0598 in, 16 gauge is about two-thirds thicker than the 20-gauge body that most budget tool chests use. That thickness is spent in the right place: a cart shelf is a small panel that takes point loads and gets dropped on, which is harder service than a drawer bottom. It is also why the Sunex's 350 lb rating is the most interesting number on the page - the heaviest published steel carries the lowest steel-cart rating, which tells you the rating is set by something other than shelf thickness. Sunex does not say what, and we will not guess. The full gauge reference has the conversions.
Casters decide whether the cart gets used
A cart that does not roll where you need it becomes a shelf. The two figures that matter are diameter and configuration.
- Diameter. A 5 in caster rolls over a slab joint or an extension lead that stops a 4 in caster. The WEN 73009 is the only cart here on 5 in wheels.
- Swivel versus fixed. Four swivel casters turn the cart in its own footprint, which is what you want between a car and a wall. Two fixed casters track straight and resist turning - better over distance, worse in a single-car bay.
- Brakes. Many garage floors slope toward the door for drainage. A cart without brakes drifts on a slope, and a loaded one drifts into the car. The WEN 73163 publishes two foot brakes; the Sunex publishes two locking casters.
- Tread. Non-marring casters protect a coated floor. Hard polypropylene casters are louder and can mark epoxy.
Casters, in detail covers tread materials and what a caster rating does and does not include.
Steel or plastic
| Steel cart | Polypropylene cart | |
|---|---|---|
| Magnets | Takes magnetic trays and bars - sockets stay where you put them | Nothing sticks to it |
| Fluids | Powder coat protects it until it chips, then it rusts | Never rusts; brake fluid and coolant wipe off |
| Impact | Dents, but a dent does not stop it working | Does not dent |
| Casters in this roundup | GEARWRENCH publishes hard polypropylene; Sunex publishes no tread type | Both WEN carts publish non-marring casters |
| Weight | Heavier to lift into a vehicle | Lighter |
For automotive work, magnets tip it toward steel: a magnetic tray on a steel cart solves the rolling-socket problem without a lip at all. Magnetic tool holders covers the bars and trays, including why their pull ratings are worth reading carefully. For general garage work around fluids, plastic is the lower-maintenance answer.
Before you order
- Measure the gap you will park it in - beside the car, under the bench, between the machines. A 36 in cart does not fit a 30 in gap.
- Check the top shelf height against your working height. A cart you stoop to is a cart you stop using. Bench height from your own body applies here too.
- Look at your floor. Cracks and cords mean 5 in casters. A slope means brakes.
- Decide whether you need magnets. If yes, steel is the only answer.
- Put the heaviest thing you will carry on one shelf, and ask whether the cart publishes a figure that covers it.
What we would skip
A list with no losers is a list nobody edited. These are the choices we would actively steer you away from, and why.
Any cart whose listings disagree about its capacity
It is common in this category for the same model number to carry one capacity on one listing and double it on another. When that happens there is no published figure, only two claims. We left those carts out rather than choose between the numbers.
A cart with 3 in casters for a garage slab
Small hard casters stop dead at expansion joints, cords and a dropped washer, and the cart's momentum carries the load forward off the tray. On concrete, 4 in is the working minimum and 5 in is noticeably better.
A drawer cart, if what you needed was a cart
A cart with a bank of locking drawers is a small rolling cabinet. It is useful, it is several times the price of an open-tray cart, and it no longer does the job of carrying loose parts to the work. If you want drawers, rolling tool boxes is the page.
Flat-edged shelves for automotive work
A shelf with no lip is a table. Anything round - sockets, bolts, a drain plug - will find the edge on the first bump. Look for a published lip depth or visible barrier walls.
The honest verdict
Buy the Sunex if you want steel and want to know what steel it is. Buy the WEN 73009 if you want the one cart that tells you what each shelf holds, on the wheels most likely to roll over your floor. Buy the WEN 73163 if the problem you are solving is small parts ending up on the floor. And buy the GEARWRENCH if you want the most capacity of any steel cart here and plan to stick magnets to it.
None of them publishes everything, and that is the category rather than a failing of this shortlist. The useful habit is to read the number each maker chose to print, and to notice the ones they left out.
Common questions
What is the best tool cart?
For a steel cart, the Sunex 8005SC, the only one here whose maker publishes its steel - 16 gauge - with a 350 lb capacity and two locking casters. For a plastic cart, the WEN 73009, the only one that publishes a per-shelf rating (250 lb per shelf, 500 lb total), on 5 in casters.
How much weight can a tool cart hold?
Published totals on the carts here run from 300 lb to 500 lb, but a total assumes the load is spread evenly across every shelf, which is not how carts get loaded. Only the WEN 73009 publishes a per-shelf figure (250 lb). For the others, do not divide the total by the shelf count and treat the result as a rating - it is not one.
Is a steel or plastic tool cart better?
Steel takes magnetic trays, which keeps sockets and small parts in place, and dents rather than cracks. Polypropylene never rusts, wipes clean of brake fluid and coolant, and is usually on non-marring casters. Automotive work tends to favor steel for the magnets; general garage work around fluids favors plastic.
What size casters should a tool cart have?
4 in is the working minimum on a garage slab, and 5 in is noticeably better over expansion joints and cords. Four swivel casters turn in place in a tight bay; two fixed casters track straighter over distance. On a sloped floor, get brakes.
What is the difference between a tool cart and a rolling tool box?
A rolling tool box stores tools and happens to move. A tool cart is built to carry tools and parts to the work and hold them there while you use them - open trays, a push handle, and the lip depth and caster size that decide whether it does that job.
