STROPOL ANTITHEFT DRAIN PLUG M18 AL
High security drain plug for heavy vehicle tanks.
STROPOL is a small, highly engineered device dedicated to the big job of protecting the main drain hole of heavy vehicle tanks against removal and access by non-authorised operators. STROPOL is made of precision machined aluminium components and simply replaces the original drain nut.
Once tightened through clockwise rotation using a hexagon allen key, the crown of STROPOL will rotate freely in the anti-clockwise sense, making removal impossible for non-authorised operators. STROPOL must be installed on an empty tank.
