Dubuque Universal Aluminum Bar Clamps
These universal bar clamps are made of high quality extruded aluminum for both light weight and strength. The head of the clamp is riveted for rigidity and the adjustable foot wraps fully around the bar for tight clamping action. Detents are spaced 5/8" apart for quick adjustments. The clamp sits upright and is well balanced for ease of use. These clamps have a large “wing” type knob for good clamping pressure without causing fatigue.
Screws have 1/2" acme thread
Made of extruded and injection molded aluminum alloys
For at least the last hundred years, cabinetmakers have relied on iron bar clamps. With the advent of aircraft grade aluminum, those heavy clamps are obsolete. These aluminum bar clamps are made with the finest quality aircraft grade aluminum, making them extremely strong, without the cumbersome weight of iron clamps. If you need any more clamping force than these clamps can provide, you need to go back and fit your work better, or you could be setting up internal stresses that will cause problems down the road. All of these clamps are made by Universal Clamp Company in Dubuque, Iowa. The name Universal Clamp Co. is not as well known in the market as the traditional clamp makers, however, the quality is truly unparalleled.
