Spin Lock - FSS 754-200 - 2 in. Locking Security Cap with MxM Threaded Adapter

The FSS-754 Versalock security cap is a quick and inexpensive way of safeguarding costly fuel and oil from theft, tampering and vandalism. It is designed for use on mobile fuel transfer tanks as well as above ground commercial gas and distillate tanks. The FSS-754 uses built in valves to equalize the pressure and vacuum. It also incorporates patented "free-spinning" technology, its one piece (padlock free) design eliminates torque points making it virtually impossible to remove without the key, most tank lock caps use a simple padlock which can be broken, cut off or leveraged with a crow bar. The FSS-754 secures to the filler neck and will freespin until unlocked.


With skyrocketing fuel prices theft is on the rise. The cost of the FSS-754 security cap is small compared to the cost of the fuel in your tank. The FSS-754 is different from any other cap on the market, in that, the cap is secured to the filler neck by our unique patented technology. When the cap is in secure mode the cap will freespin making it virtually impossible to remove.
