Every question, answered.

That's the whole design brief. Cart-path joints, turf bumps, a hard brake at the tee box — the wide flexible base spreads across whatever it's sitting on, and the fins hold the drink from underneath so a jolt doesn't send it over. It resists tipping and settles back level.

The stock well is sized for a slim can, not a tumbler — that's the exact gap this closes. A base 2 to 3 inches across settles in, and the 40 oz Stanley fits. Handled mugs don't; the handle gets in the way of the fins.

No. Nothing clamps to a rail, wedges into the dash cutout, or hunts for a magnet-friendly patch of steel. It sits on top of whatever's flat and picks up in a second when the round's over.

Wherever the drink is. On the dash next to the factory well, on the bench seat for the third player, on the floorboard, or on the rear flip seat that never got a holder of its own.

That's the one thing nothing on the cart is built for. The lidless clubhouse cup drops right in and the fins hold it from the sides — no lid required.

Yes — repeated joints and turf bumps are exactly the movement it's built to shrug off. It's not magic, so a direct hard kick is still a direct hard kick, but the steady jolt of a normal round is the job.

Yes. It doesn't need a factory holder to sit in — it sits directly on the flip seat's deck or armrest, so backward-facing riders finally get a spot for their drink too.

Rinse it or run it through the dishwasher — one piece of flexible material with nothing to come apart, and no koozie to dry out.

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

Probably not exactly — dash cutout shapes and dimensions differ across Club Car, E-Z-GO, and Yamaha, and can shift again by model year within one brand, which is why inserts marketed as universal so often don't seat flush. This doesn't ask the dash for anything: it sits on top of the dash, the bench, or the flip seat instead of trying to match an opening, so it isn't tied to any one manufacturer's cutout.

That trick solves the diameter problem but creates a new one: the drink hangs below the dash and swings with every turn and bump instead of sitting still, and it only works for tumblers that happen to have a handle in the first place. This sits the tumbler down inside a base instead of hanging it off an edge, with fins closing around the bottom inch so it doesn't swing.

A bare 12 oz can runs about 2.6 inches across its base — comfortably inside the 2-to-3-inch range. A foam koozie adds width on top of that, so expect a snugger seat nearer the top of the range rather than the loose middle a bare can gets, but it's still within what the fins close around.

A slim or 'sleek' 12 oz can measures roughly 2.25 to 2.28 inches at the base — toward the loose end of the fit range, but still above its 2-inch floor — and the fins close around that width instead of leaving the gap an oversized stock ring does. It's a tighter, steadier hold than a slim can gets rattling loose in a well sized for a wider standard can.

A container base from 2 to 3 inches across settles in fully, and the fins flex to seat bases as wide as 3.15 inches for a snug fit — past that is an honest no. On the cart, that range runs from a standard 12 oz can (about 2.6 inches) up through the Stanley 40 oz H2.0 FlowState Quencher Tumbler (3.1 inches) and the Stanley 30 oz H2.0 FlowState Quencher (3.15 inches, right at the flex ceiling).

Yes — nothing about it is course-specific. Communities built around cart life, like The Villages, run carts over the same kind of joints and dips as a cart path, just on a dedicated path network instead of a fairway, and street-legal LSVs capped at 25 mph still deliver the same kind of jolt to whatever's riding along. It sits on the dash, bench, or flip seat the same way whether the destination is the next hole or dinner.

Most groups get by with two or three — one for the bench seat's third drink, one for the flip seat if it's in use — since the stock dash wells already cover the driver and front passenger. Rounds that lean on the beverage cart tend to want an extra one specifically for the open cup that otherwise has nowhere to ride.

A practical one. Most golfers already know their dash well won't take a 40 oz tumbler and haven't found a fix that doesn't involve a clamp, a magnet, or drilling into a cart they may not even own. It's useful straight out of the box, with nothing to install and no cart brand to match.

It's a single molded piece with no fabric lining, foam sleeve, or seam for a spill to sit in — a rinse or a trip through the dishwasher clears a spilled transfusion or a sweating can the same way it would any hard plastic dish. There's nothing absorbent in it to hold a stain the way a cloth koozie would.
