Secure boxes for site documents, keys and small valuables. Wall mounted and freestanding options.



These boxes combine security with containment — a locking steel enclosure with a sump, for storing flammables, fuels and hazardous materials on site where both theft and spillage are risks.
Work from the containers you need to store and the sump capacity that implies, then check the footprint and access. Kerbside delivery means you also need a way to move it into position.
Keep the box away from ignition sources, drains and site boundaries where it is visible to passers-by. Anchoring or positioning against a structure makes removal harder.
A security box combines a secure enclosure with spill containment for hazardous materials. A standard site box is for tools and equipment and has no sump.
Work from the containers you intend to store and the containment that implies, then check the footprint and how you will move it into position.
Away from ignition sources and drains, and out of easy view from the site boundary. Anchoring or siting against a structure makes theft harder.
