Product Description

The Sentinel is the smallest and most compact metal garden storage unit in the Trimetals range, providing strong, secure, and convenient storage for small gardens and where outdoor space may be limited. The unit has a simple, low-profile design, and is ideal for storing and protecting a wide range of outdoor items such as small gardening tools and equipment (e.g. strimmer’s and pressure washers), home DIY tools, garden pots and planters and much more.

Strong, lockable and maintenance free garden storage

The Sentinel is manufactured in the UK using PVC coated galvanised steel which is fire-resistant, maintenance fee and guaranteed for 25 years. The unit’s all-metal construction makes it strong, secure and highly durable and unlike plastic or wooden sheds it will not warp, become weak and brittle or crack and discolour over time, even in coastal locations. The unit comes fitted with two secure padlock points and is designed to be bolted down from the inside to a hard surface, enabling your valuable tools and equipment to be securely locked away and protected from theft as well as the elements.

Unique “walk-in access” design / Simple DIY construction

The Sentinel features Trimetals’ unique and easy to use spring-assisted opening action, which allows easy and complete “walk-in” access, making it simple to access heavy and bulky stored items, effectively eliminating the need for heavy or awkward lifting. The unit is supplied in a convenient flat pack and is simple to construct, with all major components being supplied pre-assembled including the door and roof. The unit comes with easy-to-follow illustrated assembly instructions and all necessary fixings. Trimetals recommends assembly of the unit is undertaken by a minimum of two people.

Options and upgrades

The Sentinel storage unit is available in a two-tone green colour, consisting of an Olive Green roof and Moorland Green side panels. Optional accessories are available including a pre-cut exterior grade plywood floor (which provides extra protection for your stored items and protects the metal floor from scratches), a pair of brass padlocks with hardened steel shackle, and hasp and padlock sets to enhance the security of your storage unit.
