ZaCK drain is a robust security padlock designed to block the drain hole of the fuel tank and/or the discharge valve of the water/diesel separator filter. Points that are easily accessible to any malicious person who wants to carry out a fuel theft.

The compact design makes it stand out by only 8mm more than the original cap, without modifying the heights established by the vehicle manufacturer.

ZaCK drain is simply closed and hand-tightened. Once tightened and in position, it will suffice to press a button on the lock and no one will be able to unscrew it without the key as it rotates freely by itself .

The bright yellow plastic cap has the task of protecting the lock from dust and mud and leaving evidence if someone has tried to gain access to the lock.

To remove it, it is necessary to break it as provided in its form.

Manufactured in Avional, ZaCK drain anti-theft guarantees high mechanical resistance and high resistance to corrosion.
