We all use the modern version of these clamps in our shops - hard maple with a metal threaded rod and some specialty hardware. But think of the pleasure you'll feel when, on your next assembly, you use a pair of handscrew clamps that you build yourself - all solid hardwood right down to the threaded hardwood screws and the laminated jaws.

Approx: 2-1/4'' x 16'' , and about 20'' when the screws are fully extended.
