The FSS 720 is your solution to diesel fuel theft. It was designed specifically to secure stationary storage tanks with 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 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 without the key.
