Function of Swivel Coupler
Swivel Couplers connect two scaffold tubes at any angle to provide a ledger brace, or similar bracing. These are also key components in the structure and must be load bearing. The body is firmly riveted to permit rotation but still ensures the minimum of further movement, for maximum rigidity. Again, the T-bolts can be removed for maintenance.
Quality Control
We have been granted the SIGMA Certificate after 16 months of continuous efforts of making, shipping and improving products to be tested in Germany. All the hard work and waiting is paid off and our clamps have finally passed all the tests conducted in Germany and the certificate is issued to us on 6th , of Oct. 2015.
