ABSTRACT:
The multi-purpose Combo Jack.TM. tool combines the functions of a ladder jack, a roof bracket and a roof hooks into one piece of equipment. There are a pair of hooks attached to a rail supporting arm which is pivotably connected to a bracket body arm. The bracket body arm includes the plank stop lever and a retractable nailing blade. A combination support arm is connected to the rail support arm at either the tri-function setting or the steep roof bracket setting, and is also connected to the upward or downward slots in the bracket body arm (or at the end but not in a slot). The tool includes a safety stop as part of the retractable nailing blade, a ladder lock, and a safety protrusion to prevent collapse of the tool because of slippage along the bracket body arm by the combination support arm.
