ABSTRACT:
A clamp jaw extender is adapted to be releasably attached to each jaw of a standard bar clamp to substantially increase the clamp depth thereof. The extender comprises a clamping member having a mounting slot defined on a back side thereof for detachably mounting the clamping member on a jaw of the standard bar clamp and a pressure pad on the upper end and frontal side of the clamping member. A pair of laterally spaced mounting flanges are formed on a lower end of the clamping member to define a mounting slot. A pair of upper and lower bearing and guide rollers are preferably mounted in the slot for slidably mounting the clamping member on a slide bar of the standard bar clamp to convert the bar clamp to a deep jaw bar clamp.
