Designed to ease the installation of kitchen cabinets, drywall ceilings, and tub surrounds, the T-Jak support tool can support objects weighing up to 400 pounds. A quick-release knob engages the tool’s threaded rod to lock it into place; twisting the knob allows users to fine-tune the height from 53 inches to 84 inches. The Original Cabinet Jack costs $126 on the company’s website; 1-, 2-, and 3-foot extensions are sold separately, starting at $26.
