Spacing Wedges enable better fit-up of pipe ends. Wedges are used to create precise weld gap. Simply move the pipe ends together, mount and tighten the chain clamp or cage Clamp and spread the gap to the desired width using the Spacing Wedge. The wedge portion of the Spacing Wedge is case hardened for long life, while the upper part of the Wedge is soft enough to prevent splintering.
