A multi-purpose metal fire box lined with intumescent, with one detachable face for ease of fitting. Using a sharp blade, the sponge allows for cutting to feed cables, cable trays, pipes, etc. Lined with intumescent along the internal edges and expands inwards at high temperatures. In effect, the intumescent creates a powerful fire and smoke seal. In the event of a fire, the intumescent expands to form a fire as well as a smoke seal, preventing smoke and fire from spreading.

Designed with fixing brackets to attach using screws onto surfaces around services, including services located in difficult corners. Fire boxes are available in longer sizes to accommodate several pipes or services passing through walls or ceilings.

Suitable for recessing into hollow plasterboard walls. Furthermore, when required, the fireproof sponge is easily replaced. Available in various sizes to accommodate large pipes and, where required, also made to order.

– A versatile solution to the problem of services passing through walls, floors and ceilings, offering up to 4 hours protection

– Detachable face plate allows for the box to be fitted in tight corners

– Adjustable brackets can be bent flat to fit flush against flat surfaces such as walls or ceilings, or kept at a right-angled position to fit in corners
