Dewalt dwht83550 Construction Jack 340 Lb

Product Description

The DEWALT dwht83550 is a manual construction jack designed for lifting, leveling, and holding materials during finish installation work. Each jack delivers up to 8.75 inches of lift height and supports up to 340 pounds of load capacity. The step-to-lift foot pedal frees both hands during positioning, while a squeeze-style lift mechanism handles confined spaces where foot access is limited. Controlled lowering allows fine, incremental adjustments so installers can dial in reveal, plumb, or alignment without dropping the load. These jacks are used by finish carpenters, cabinet installers, door and window crews, and HVAC technicians who need stable, hands-free support during placement and fastening.

These construction jacks are suited for residential and light commercial finish work. Common applications include raising prehung doors to final position, supporting cabinet banks while checking layout lines, holding window assemblies during shimming, and positioning HVAC equipment during placement. The slim tapered base slides under workpieces with minimal starting gap. Countersunk holes allow flush-mount setups when a more fixed configuration is needed. Running both jacks together under a longer cabinet run or window assembly provides balanced support, which is particularly useful for solo installers working through setup and leveling without a second person on site.

Installation Notes

These jacks are typically deployed by finish carpenters, remodelers, and installation crews working on doors, cabinetry, windows, and similar finish elements. Before placing a load on the jacks, verify the floor or subfloor surface is level and capable of bearing the combined weight of the jack and workpiece. Do not exceed the rated 340 pound capacity per jack. Always lower the load in controlled increments and confirm the workpiece is fully secured before removing jack support.
