DeWalt DWHT83550 ToughSeries 8-3/4 in. 340 lb. Capacity Construction Jack Overview
The DeWalt DWHT83550 ToughSeries 8-3/4 in. 340 lb. Capacity Construction Jack is a hand-powered construction jack designed for lifting, leveling, and holding materials in place during installation work. This is a construction jack designed for hands-free lifting and precision positioning when you are working solo or when the workpiece needs to stay put while you fasten.
On the job, the big story is capacity and usable lift height. This jack supports up to 340 pounds and lifts up to 8-3/4 inches, which is right in the zone for setting prehung doors, bumping cabinets into final height, leveling window units, and dialing in flooring transitions. It is a practical alternative to shims when you need repeatable, adjustable lift instead of tapping and guessing.
The step-to-lift function (enabled by the reinforced handle) lets you raise the lift plate while keeping your hands on the work, which is exactly what you want when you are trying to keep a door jamb plumb or a cabinet tight to a line. There is also a squeeze-to-lift style grip for controlled raising when you are working in tighter spots.
When it is time to come back down, the controlled lowering tab is what keeps this tool from being a one-trick lifter. Controlled lowering lets you make small, predictable adjustments for leveling and alignment, instead of dropping the load and starting over. That matters when you are chasing consistent reveals on doors or keeping a window square while you drive fasteners.
For access under workpieces, the slim, tapered base helps you get under material quickly, and the countersunk holes support flush mounting when you need the jack secured to a surface for stability. The overmolded handle with reinforced metal ribs is there for comfort, but more importantly it is there for support when you are lifting near the tool's rated capacity.
If you do remodeling, finish carpentry, cabinet work, door and window installation, or HVAC equipment positioning, this is the kind of tool that saves time because you stop improvising with wedges and pry bars. It is also a solid fit for anyone who works alone and still wants clean, repeatable setup and leveling.
- Tool Type: Construction jack (hand tool)
