ABSTRACT:
A ladder vise assembly which is adapted for attachment to a step or ladder rung for immovably holding pipes and other suitable work materials. The assembly includes a stationary first clamp attached to one leg of a rung of a ladder with a vice module integrally built on it. A second clamp is adjustably spaced along a horizontal bar away from the first clamp. Both clamps include rotatable knobs for opening to receive a pipe and closing to hold the pipe firm in position. The vice module is slidably connected to a horizontal bar which connects the two clamps. An adjustable pipe-holder attachment is adapted to be affixed either to a wide bottom or narrow upper portion to of virtually any step ladder. A hole for locking the vise to a ladder is disposed within a bottom portion of the adjustable clamp to prevent removal.
