Stressing Heads – RSXSHPK

The stressing head applies a temporary stressing force to the tendon and maintains the load until the lock-offload is transferred to the anchor head. The stressing head assembly should be used in all applications to insure uniform strand tension. Anti-seize compound is available to assist stressing head release.

 


 

Stressing Chairs – RSXSCP

The stressing Chair utilizes a keeper plate to adjust to an applicable distance for 3-part wedge sets. The stressing chair assembly can be used for proof testing of the strand anchor assembly, incremental lock-off loading, or typical installation loading
