About the RSA/15 & RSA/20 Storage Units

The RSA/15 & RSA/20 Outdoor Storage Unit

The RSA/15 (420 litres) and the RSA/20 (560 litres) are small outdoor storage box with generous capacity. The body of this unit is made using fibreglass, with the lid being made from glass-reinforced plastic. This allows your outdoor storage unit to remain outside all year round, no matter the weather.

Whether you’re looking for an outdoor storage box for cushions, toys or outdoor games, this is a multi-use storage unit that can be custom-made for any setting. We’ve previously manufactured and delivered these storage boxes for gardens, parks, playgrounds and supermarket chains.

This waterproof outdoor storage box protects contents inside the unit from water damage. The optional gas struts allow the lid to be opened and closed with ease, with a soft-closing mechanism so the lid doesn’t slam shut, avoiding potential injury.

To get the most out of your unit, you can choose to have two compartments to separate contents inside the outdoor storage box, a handle for easy access, a hasp & staple for enhanced security and castors for easier manoeuvrability. For a customised unit, choose from a textured or smooth finish with a range of body and lid colours, including vinyl lettering to signify what must be stored in the box.

Looking for a larger outdoor storage box? Our RSA/30 is 840 litres and our RSA/35 is 960 litres.
