These are brand new band clamp rings made from 304 stainless steel.  These will fit all Voit and US DIVERS two regs (except the Trieste).  Using this simple and inexpensive option lets you ditch the c clips and enables you to open your regs in seconds without the torture and damage to the chrome of your vintage reg.  These are the best band clmaps ever made, even better than the OEM ones.

$20.00 each plus $3.00 shipping.
