Bessey’s clamp extenders let you use a small clamp to do large jobs. They made the extenders to be used in conjunction with their DuoKlamps, but they should work with just about any clamp larger than 6″. The extenders can be used to clamp workpieces up to 65″ with 260 lbs. of force, or you can reverse the jaws to spread up to 70″.
The extender consists of two 36″ long bars which slide past each other and a set of inner and outer jaws. Both bars run through the inner jaws, which can be positioned anywhere as long as they’re over both bars. One inner jaw locks onto one bar, and the other jaw the opposite bar. By compressing the inner jaws, the bars pull on the outer jaws exerting the clamping force.
The DuoKlamp Extender runs about $30. Considering that an inexpensive parallel jaw clamp costs only a little more, are these extenders overpriced, or are they worth the money? Let us know in comments.
