Our verdict

A sturdy, well-built jack for hands-free lifting and clamping on the jobsite, with a lowering mechanism that a few buyers found too easy to fully release by accident.

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

Pros
  • Smooth ratcheting lift for drywall, cabinetry, and doors
  • Footplate converts to a clamp for extra holding tasks
  • Non-marring pads protect finished surfaces
Cons
  • 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.
