UD Series Clamps
Heavy Duty Double Edge (Closed End)

This double edge closed end clamp provides maximum strength by restricting the saddle from expanding by either welding a clip on the open ends or by an exclusive Clamps, Inc. design of rolling a tab over. Clamps, Inc. provides the tab over feature in our most popular 4” and 5” saddles which eliminates the possibility of having a clip come off and jeopardize the integrity of the clamp.

The UD-Series is available in a variety of sizes and finishes.
