The 3 x 7 shed has plenty of storage inside and can handle most outdoor storage needs. Not only will the Sentry meet your garden storage needs, but an optional bike hanger will also allow you to store a single bike on the wall, with a second bike on the ground, creating an instant double bike storage locker.

Weatherproof slimline metal shed

This fully weatherproof (rust-resistant galvanised metal) garden shed is suitable for every size and shape of garden. A fully integral all-metal floor gives the Sentry shed incredible strength and security, bolted down to the ground using the supplied floor bolts and you have exceptional garden security. Inside the heavy-duty all-metal construction you will find a pick & drill resistant Euro Cylinder locking system. Up-top you will find two ventilation systems, in the roof eaves and in the front fascia, designed to maintain airflow inside the locked shed, keeping condensation to a minimum. Upgrade your shed to include hooks, tool rails, and shelves to store even more! The Sentry shed is supplied with a 10-year warranty and free delivery to most of the UK.
