Every question, answered.

That's exactly the surface it's built for. Hard, flat ground is where the wide base and the fin grip do their best work — it holds steady on painted steel, concrete, or a workbench at least as well as it does anywhere else, no magnet or clamp involved. Bump it and it settles back instead of walking toward the edge.

No. It doesn't rely on a magnet, so it works the same on a wood bench, a painted fender, a plastic cart, or the shop floor. Ferrous or not, flat is all it needs.

Measure the bottom, not the rim. A base of 2 to 3 inches across settles in — the 40 oz Stanley does. A handled coffee mug doesn't; the handle lands where a fin needs to grip.

No. Nothing clips to a drawer lip, bolts to a frame, or sticks to anything. It sits on top of whatever's flat and moves with you from bay to bay.

That's the everyday case it's built around. The base flexes and resettles the drink when a tool or a cart shoves it — it resists tipping, not a direct hard hit, but the steady shake of shop work is exactly what it shrugs off.

Yes — it holds on the cart top the same way it does on the bench or the roll cab, so crossing expansion joints and thresholds doesn't send the drink sliding into the tray lip.

Nothing about this magnets or clamps on, so it doesn't ride the lift post the way an aftermarket magnetic holder can — it needs a flat spot to rest on, and there isn't one up there. Set it on the nearby cart, the bench, or the floor by the post instead of chasing a spot at working height.

Rinse it or run it through the dishwasher. It's one piece of flexible material with nothing to trap grit or come apart.

It's called the Steadi. Steadi Labs molds it in small runs in Orange, California — veteran-founded, patent pending — and every order ships free from steadilabs.com, with 30 days to send it back if it doesn't earn a spot in your bay.

Yes, across the sizes that actually ride in a bay. Monster and Red Bull 16 oz cans share a 2.6-inch base, a standard 12 oz can runs the same 2.6 inches, and the narrower "slim" or "sleek" 12 oz cans (Celsius, Alani Nu, White Claw-style seltzers) measure about 2.25 to 2.26 inches. All of it sits inside the 2-to-3-inch range and settles in fully.

A magnetic holder only grips bare ferrous steel, so it's dead weight the moment you're at the workbench, on the car, or on the floor — everywhere the actual work happens. It also depends on being set down dead level or it slides off. This one doesn't rely on a magnet at all, so it moves to whatever surface is flat that day, steel or not.

Packout drinkware locks into the Packout stack, so it only works wherever that stack lives — the truck, the shelf, the box lid — not wherever your hands happen to be at the moment. It also means buying into that ecosystem just to hold a drink. This sits on any flat surface in the bay without locking to anything, so it moves with the job instead of staying behind with the boxes.

Those clip designs are sized to one specific lip thickness — a popular one fits about an eighth of an inch and nothing thicker — so a holder built for one box's drawer edge usually won't fit the next box, the bench, or the cart. It's also printed plastic living next to brake clean and impact sockets. This one doesn't clip to a lip at all; it rests on the surface itself, so any bay, box, or bench works the same way.

It's one piece of flexible material with no fabric, seams, or stitching to trap grit or hold onto grease. Rinse it at the sink or run it through the dishwasher between shifts and it comes back the same shape it went in — there's nothing bolted, glued, or clipped on that a solvent-heavy bay can work loose.

Yes — nothing about it is hinged, bolted, or clipped together, so there's no joint to snap when it gets stuffed in a bag or a drawer. It flattens down for the ride and takes its shape back the next time it's set on a flat surface.

It's a small, specific answer to something almost every shop deals with and hasn't really fixed with a magnet or a mount. Nothing to configure to a particular box, cart, or truck. It ships free and molded in Orange, California, with 30 days for them to decide it earns a spot in the bay.

Plenty of people do. A pro bay and a home garage or driveway job share the same flat, hard, vibrating surfaces — a roll cab or bench, concrete either way — so the same base works in both. Since nothing clips or magnetizes it to one box or cart, it can also just ride along from the Saturday brake job back to the shop Monday; a second one just saves you remembering to bring it.

Both are honest no's, for opposite reasons. A Big Gulp-size fountain cup is too wide for the base to grip; a paper espresso cup is well under the 2-inch floor and just sits loose in the middle. The 2-to-3-inch base range is what settles in — those two land outside it on either end.

Yes. The surfaces don't know the difference between flat-rate and a Saturday brake job. A fender cover is just as slick, a driveway floor is just as hard and just as out of sightline from under the car, and a home workbench carries the same impact-gun and grinder vibration as a shop bench. It's built around the surfaces, not the paycheck.
