Designed to create robust anchor points for securing all your valuable shed contents, such as mowers, chainsaws and bikes, the 3'3 (1000mm) Bull Security Stronghold Underfloor Locking Kit will deter thieves and give you peace of mind.

The kit is best fitted during installation of your wooden shed floor. Simply place the 1000mm box section under the floor. Then, from above and through the floor, secure the eyelets to the steel box below. Once fully inserted, the eyelets are not removable, each creating a robust anchor point. Then wrap a chain or thick wire cable (not supplied) through the eyelets and around your valuable items. Secure this with a padlock (not supplied) and your shed contents will be safe and sound.

The heavy-duty 12mm eyelets and galvanised steel bar with powder coating are maintenance free.
