While it’s frequently said that you can never have too many clamps, often the real problem is not having ones long enough for the job at hand. Ideal for those situations, these unconventional clamps are not limited by the length of their bars. Driven by an Acme-threaded screw, one jaw registers against an outside face of the work, while a cam-action clamp serves as the opposing jaw, grasping the work a short distance from the joint. This not only lets you secure work much longer than the clamp itself, but the short span also helps prevent long stock from bowing.

Unchanged in over a quarter century, they are still produced by the Dubuque Clamp Works in Iowa, cast from lightweight, rigid aluminum. On the 11 3/4" long face-frame model, the cam jaw is oriented horizontally; the 9" shelf clamp has a vertically aligned cam jaw. Both accept stock from 5/8" to 7/8" thick.

Jaw brackets, and a miter attachment are available separately.
