The Best Things
Universal Clamps by Dubuque Clampworks

For at least the last hundred years, cabinetmakers have relied on iron bar clamps. With the advent of aircraft grade aluminum clamps, we feel that those heavy iron bar clamps are obsolete. The aluminum bar clamps we offer here 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, which is about 1000 pounds, then you need to go back and fit your work better, or you will be setting up internal stresses in your work that will cause problems down the road. Universal Clamp Company was bought by Dubuque Clampworks and these clamps are now all made in Iowa along wth their famous hand-screw clamps. They were originally made in California, but that is now some years ago. The quality of all Dubuque Clampworks products is truly unparalleled. Trust us on this one, these are the best and most useful bar clamps that any cabinetmaker could own.

UC 900 Adjustable Bar Clamp Series

- Each size can accomodate work up to the specified length (i.e. a 24" clamp will handle a 24" piece of work).
- All clamps have a moveable pad with spring action that lock in any of the punched slots that run the length of the bar.
- The clamps will sit upright so that work can be placed on the clamp.

Universal UC-905A Mitre Attachment for UC-900 Aluminum Bar Clamp

The UC-905A miter attachment pieces slide onto the jaws of the UC-900 aluminum bar clamp. One side fits the outide of a miter and the other piece fits the inside. To span a square object two outside pieces can be used on one clamp. The working surfaces of the inside piece are covered with abrasive paper which helps for the clamp to pull joint tighter as the clamp is screwed tight.
