ABSTRACT:
A backer-rod installation tool for forcing a backer rod to a predetermined depth. A first rotatable wheel is rotatably mounted to a frame and is extendible into a building slot to contact a backer-rod. A pair of outer wheels are rotatably mounted on either side of the first wheel contacting the outer building surface and limiting the extension of the first wheel into the building slot. The outer wheels are adjustably mounted to the frame to adjustably control the extension of the first wheel. In an alternate embodiment, the outer wheels are replaced by a single outer wheel. In one embodiment, the wheels are mounted by means of rods having flat surfaces contacting fasteners limiting rotational movement of the rods relative to the frame of the tool.
