'H' clamp

Advantages of this design are: (1) The H clamp is not not type specific so can be used with any existing clamp with sufficient throat depth, (2) H clamp has 2 pressure points reducing the number of clamps required & spreading the load, (3) H clamp does not swivel the main clamp the work, (4) H clamp is low cost compared to other 3 way clamp designs and is more efficient then single screw attachments.

Note. Because of the nature of the forces generated the main clamp may slide on the work & damage it (this is true for any other 3 way screw clamps). We strongly recommend the use of the powergrip grip kit which overcomes the problem.
