DESO SL1000B Tank Lock - Oil Tank Security For DESO SL1000B

For maximum security, fit this large single lid lock to the outer tank. By securing the large lid of the outer bund it is very difficult to gain access to the inner tank.

This lock fits bunded Deso oil tanks with similar lid to that shown in photo below, e.g. Deso H1800B, H2500B, R1220B and SL1000B.

Materials: All Tank Arms are made from 5mm thick solid steel. The steel is zinc plated and assembled with a stainless steel tamper proof rivet, providing an anti-corrosion barrier so the arms will never rust or seize. The 2" aluminium cap is attached to the arm with a hardened steel pin, welded at both ends, to prevent removal.

Padlocks: We do not include a padlock, as some customers will have one already. However a padlock is required. We recommend the Wordlock padlock.

Installing Tank Arm

The Tank Arm oil tank lock can be fitted without any drilling. However, some people may find it easier to drill pilot holes first. In such cases, we recommend a 3mm drill bit, for sale online for 80p. See our 3mm drill bit page for more details.
