GROZ T Bar Heavy Duty Sash Cramp Clamp-900mm GZ-39100


A robust set of cramps designed for applications that require extra resilience under extreme pressure, these can be permanently fixed onto the workbench as well.
The “T” section bar is made from special cold drawn steel with a section of 1” x 1.5/8” which offers great resistance to bending in use. Malleable iron head and slide allow these cramps to be used in extra heavy duty applications. The main screw has rolled Acme threads for smooth movement and increased resistance to wear. The sliding head is fastened to the T Bar by inserting a steel pin through any of the locating holes on the bar. The steel bar, head and slide have an attractive powder coated finish, the main screw, handle and pins are blackened for increased resistance to corrosion.
