Irwin Record Sash Clamps
Primarily designed for the clamping of large section workpieces during joint gluing or any other large scale clamping applications.

The steel mainscrew applies pressure quickly and smoothly through a fast acting, hard wearing rolled thread.
Slides and heads are flat bottomed so that the clamp will stand without support.
