A Locking Solution for Plastic Oil Tanks

Tank Arm is an oil tank security lock for plastic single skin and bunded oil tanks. An easy to fit security device that requires no drilling, can be fitted in minutes, and secures multiple extraction points on your oil tank.

Reasons to secure your oil tank with Tank Arm

The Large Outer Lock

Secures the outer tank on bunded oil tanks

Suitable for bunded oil tanks, i.e. where the oil sits inside the inner tank, protected by an outer "bund" (a tank within a tank).

This Large Outer oil tank lock secures the lid on the outer tank, making it very difficult to gain access to the inner tank.

£60 to £75 plus VAT and delivery

The Double Lock

Secures the tank's fill point & inspection hole

Suitable for single skin or bunded oil tanks (note: on bunded oil tanks, this double lock is fitted to the inner tank).

The Double Lock protects two vulnerable outlets of an oil tank – the inspection hole, and fill point.

Price includes vent cover, if applicable (i.e. if oil tank has exposed vent).

Why Choose Tank Arm to Protect your Oil Tank and Heating Oil?

Tank Arm secures multiple "at risk" parts of an oil tank

Some oil tank security products on the market secure just the fill point of an oil tank, when in fact most oil tanks have two potential extraction points – the fill point, and the inspection point. Tank Arm (double lock) secures both. Tank Arm also comes with a vent cover where appropriate, which secures a third exposed part of the oil tank.

Tank Arm is an effective deterrent

An alternative solution to oil tank security is an oil tank alarm that omits a noise when oil is being removed – effective if the noise is heard and police are called, but if not, the thieves are likely to carry on. With Tank Arm fitted, the oil tank becomes a difficult target, and opportunist thieves are likely to go elsewhere - regardless of whether the house holder is present.

Tank Arm is robustly manufactured, and made in the UK

Made in UK

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.

Tank Arm is easy to install

Simply remove caps on your tank, place the base plate over the neck of your tank inspection hole, and screw the supplied cap onto the filling point. Join the arms together, then fit a padlock of your choice through the holes. The base plate is then screwed to your tank using the one way tamper proof screws.

Tank Arm can be fitted without drilling, however some people may find it easier to drill pilot holes first. Read our basic installation instructions here, although you will receive full installation instructions with your purchase.

Tank Arm offers value for money

Tank Arm is competitively priced, and comes with all fittings required for installation. We also include a vent cover where applicable (not applicable on bunded tanks for instance), for added security. Please note, we do not include a padlock, to keep costs down in case you have one already.

Our oil tank lock, "Tank Arm", has a UK Patent, No. 2494646. Patents will be applied for in other jurisdictions.
