SpinSecure FSS 754 Versalock Vented Locking Tank Cap
The FSS 754 is different than any other cap on the market, it is secured to the filler neck by the unique patented SpinSecure technology, when the cap is in the secure mode the cap will freespin making it virtually impossible to remove without the key.
Note: For 2 inch female NPT tank connections, order the SS750200 MNPT x MNPT Adapter.
