This four-pole cabinet jack set gives you enough support points to brace a full upper cabinet run or hold drywall across a wider span without repositioning a single pole. Each pole telescopes from 45.67 to 114.17 inches and holds up to 154 pounds, and the 360-degree rotating head tilts up to 45 degrees for slanted ceilings and irregular corners. A triple-lock system keeps the carbon steel shaft from slipping under load, while the non-slip foam grip and quick-release rod make it quick to set each pole's height even when placing four in a row. The wide PP and PVC foot pads keep every pole planted on the floor. At 18.96 pounds for the full set, it's still manageable to carry between jobs in the included waterproof Oxford bag.
