The Revolver FSS 720 is your solution to fuel theft. It was designed specifically to secure stationary storage tanks with either a Male or Female 2" NPT. The cap is made from hardened steel and the tubular lock has in excess of 50, 000 combinations.
The Revolver FSS 720 is unlike any storage tank locking cap, it incorporates the Spin-Secure technology which disengages the cap from the thread making it virtually impossible to remove the cap without the key.
