Overview
The Klein Tools 77000 is a hands-free construction jack rated for 350 pounds with a 10-inch lift range, built for drywall hanging, panel installs, and leveling cabinetry or doors on the jobsite. A removable footplate converts it into a clamp for extra holding tasks.
Klein built this jack with an I-beam frame and countersunk mounting holes so it holds steady under load, and the footplate swaps between a non-marring foot pad and a clamp face depending on the task.
- 350-pound lift capacity, 10-inch range
- Reversible footplate: lift pad or clamp face
- I-beam frame with countersunk mounting holes
- Lever-controlled ratcheting lift and full release
Who it's for
Suits carpenters, drywall crews, and DIYers who need a hands-free way to hold panels, cabinets, or doors in place while they work, and who are already comparing it to a DeWalt jack. Not the right pick if you need fine control while lowering a load, since the release side is reportedly touchy.
Pros and cons
- Smooth ratcheting lift for drywall, cabinetry, and doors
- Footplate converts to a clamp for extra holding tasks
- Non-marring pads protect finished surfaces
- A couple of buyers got units that jam under light pressure
- Release lever drops the load fast if fully triggered
- One buyer received a unit with oversized, loose-fitting feet
Performance notes
The jack uses a ratcheting lever to raise the load in small increments up to 10 inches, with a full-release lever for quick repositioning when there is no load on it. A removable footplate flips between a non-marring foot pad for lifting and a clamp face for securing panels, and countersunk mounting holes let it bolt down for extra stability under heavier loads.
