The hard part was never the weight. It was holding it there.

Anyone can heave a base cabinet an inch off the floor. The problem is the next ninety seconds — the ones where you need it to stay exactly at that height while you find the shim, get the screw started and check the level. That is the part that needs a second person, and it is the part that wrecks your back when there isn't one.

This is a small hand jack that takes over the holding. You slide its flat steel plate under the edge of whatever you are lifting, squeeze the grip, and the carriage walks up a toothed post one notch at a time. Let go and it stays put. Your hands are now free.

It is not a heroic tool and it should not be sold as one. It is about the size of your hand, it weighs a pound, and it lives in the drawer with the chisels until the day you are hanging a door on your own.

How much it will actually hold

This matters more than anything else on this page, so we are going to be plain about it.

The manufacturer marks these 100 kg / 220 lb. On every branded version of this same jack design we could find, that figure is the rating for a pair working together — roughly 110 lb (50 kg) per arm. Our supplier does not print which basis their number uses, so we publish the cautious reading:

One arm on its ownWork to 110 lb (50 kg)

A pair used togetherWork to 220 lb (100 kg)

Treat those as working limits, not certified ones. No independent load-test certificate ships with this tool and we do not hold one. If what you are lifting is anywhere near the number, use two arms, or use a different tool.

One more thing the number does not tell you. The load plate sticks out sideways from the post, so the weight is always off to one side of the foot. That overhang is what wants to tip the tool over. Load squarely, keep the object's weight as close in to the post as you can, and stop if the tool starts to lean.

Read this before the first lift

It is not a vehicle jack. Do not use it on a car, trailer, motorcycle or anything you would raise with an automotive jack or support on an axle stand.
It is not rated to lift or hold a person. Do not stand on it, sit on it, step on it or use it as a platform, prop or support for anyone's body weight.
Never get under a raised load. A ratchet pawl is a mechanical catch, not a safety lock. If you need to work underneath something, block it with proper cribbing or stands first.
Firm, flat, level ground only. The foot plate is small and flat. On carpet, gravel, soft earth, a sloping floor or a loose tile it can sink or slide, and the whole tool goes over sideways.
Watch your fingers. The grip mechanism scissors closed as you squeeze it, and there is a real pinch point where the linkage folds. Keep your other hand off the load plate while it moves.
Not for structural propping. Positioning a cabinet, a door or a panel while you fasten it is what this is for. Holding up joists, beams or anything a building rests on is not.
Ease it up, do not shock it. Squeeze steadily. Dropping a load onto the plate or jerking the lever puts a peak force through the tool far above the weight of the object.

The jobs it is genuinely good at

Bringing a kitchen or bathroom base unit up to the counter line and holding it there while you shim and screw.
Carrying a door slab at the right height in the opening while you line the hinges up.
Raising the corner of a dresser, wardrobe or washing machine just far enough to get a foot, a slider or a felt pad underneath.
Holding a shelf, panel or sheet of board level against a wall while you mark or fix it.
Nudging a heavy flat object up off the floor far enough to get your fingers or a strap under the edge.

Two arms is the configuration that unlocks the long stuff — a door, a worktop, a run of shelving — because one at each end keeps it level instead of pivoting.

Using it

1. Set the footStand it on hard, level ground right next to the edge you are lifting, foot plate flat.

2. Slide the plate underPush the flat load plate under the edge of the object so it sits squarely on the plate, as close in to the post as it will go.

3. SqueezePull the foam grip up to the fixed handle and release. Each squeeze walks the carriage up one tooth. Repeat until you are at the height you want.

4. WorkIt holds on its own. Shim, screw, level, fix.

5. Come back downPress the small release lever near the top of the carriage and let the load down under control, a step at a time.

What we cannot tell you

We would rather leave a gap than fill it with a number we cannot stand behind.

How far it lifts. The supplier publishes the tool's overall height but no tested travel figure, and the figure that used to sit on this page did not agree with itself. The usable lift is however much toothed post sits above the carriage — we are not going to put a number on it until the supplier gives us a real one.
The exact steel grade. It is plated steel and it is stamped, not forged. We have no material certificate, so we are not going to call it hardened or stainless.
Any safety certification. There isn't one that we have seen. Nothing on this page should be read as a certified or tested rating.
