About Multi-Purpose Box
The multi-purpose box comprises a box section housing intumescent material, with a detachable top section, allowing the unit to be used in tight corners or over existing services.
The fixing brackets are adjustable by bending them flat for fitting into corners, or when the box is flush against the floor or ceiling.
A fire-resistant sponge smoke seal is supplied with each unit.
The intumescent material can be easily cut with a knife, allowing services to pass through.
The sponge is used where service holes are not filled.
