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

Avoid the hassle of laying slabs or concrete when preparing a base for your new shed with this quick and simple to install eco plastic 7x5 shed base kit

Its interlocking design makes it easy to put together and although it is lightweight it provides a very strong and durable base for your shed.

To install the base simply interlock the square grids together and lay onto a firm, level area of ground.

Made from 100% recycled plastic, this 7x5 shed base kit is eco friendly, plus it can be reused if you wish to reposition your shed in your garden.

This handy base also allows for ventilation underneath your shed keeping it dry.

Each square grid is 500 x 500 x 40mm. This pack contains 15 squares. For your convenience, a heavy-duty, commercially-graded membrane is also included.

Please note: gravel not included with shed base

We recommend using 15kg of 10mm pea gravel per square.
