Fixing brackets are adjustable, able to be bent flat for screwing into place flush with a wall, ceiling or conventional right angle. Fit the box to walls and ceilings, or use recessed in a partitioned wall, allowing the flanges to sit flush against the surface in the cavity.
The box is lined with intumescent material that expands in a fire to seal off the gap between services, and each unit is supplied with fire-resistant smoke seal sponge that can be cut to fit around pipes and wires.
For standard open areas, simply place the box over the services, use the smoke seal if required, and screw into position. If the services are already in place, remove the detachable section, fix the ‘U’ section first then slide back the detachable section and fix the smoke seal if required. When the unit is flush against a ceiling, floor, wall, or corner simply bend the fixing brackets flat and screw into position. When using
