Klein Tools just entered the construction jack market with the Model 77000 Heavy-Duty Construction Jack — a tool designed for hands-free lifting, leveling, and clamping of panels, cabinets, drywall, and similar jobsite materials. It’s a direct shot at the DeWalt construction jack that’s been the go-to for framers and finish carpenters for years.
What the Klein 77000 Does
Construction jacks solve a real problem on the jobsite: you need three hands when setting upper cabinets, lifting drywall to a ceiling, or positioning heavy panels. The Klein 77000 gives you that third hand mechanically.
Key specs:
- Lift range: 10 inches
- Load capacity: 350 lbs
- Activation: Foot-operated squeeze mechanism — keep your hands free to position the material
- Controls: Precision lift and lower levers plus quick-release for fast no-load adjustment
- Footplate: Removable, reversible — remove it and attach to the top of the bar to convert from lifting jack to clamping configuration
- Protection: Two removable footplate covers (non-marring, anti-slip) to protect finished surfaces
How It Stacks Up Against DeWalt
The DeWalt construction jack has been the dominant name in this category for a few years. Klein’s entry matches it on the essentials — 350 lb capacity, 10-inch lift, foot activation — while adding the reversible clamping footplate configuration that DeWalt doesn’t offer. Compared to the Irwin Quick-Lift, Klein is more fully featured across the board.
Klein is a brand that electricians and trade professionals trust for hand tools and test equipment. Bringing that reputation into the construction jack space makes the 77000 an easy consideration for anyone already running Klein on their belt.

The Klein 77000 is currently available through specialty tool retailers including ToolUp and Ace Tool. Big-box listings at Home Depot or Lowe’s have not been confirmed as of this writing. Pricing was not disclosed in launch materials — check retailer listings for current pricing.
Who Needs This
Cabinet installers, drywall hangers, and finish carpenters who regularly work solo or short-handed. If you’re lifting upper cabinets, setting crown molding runs, or positioning heavy drywall sheets overhead, a construction jack pays for itself quickly in saved labor.
