The CLVM Clipper Range for Toilet Ventilation Fire Protection protects pipes used with toilet and bathroom ventilation fans from fire, with intumescent strips at both ends of the sleeve that expand in fire. The strips expand and crush the PVC pipe as it melts in heat, with up to 90 minutes fire protection. This gives more time for evacuation of buildings, slowing down the spread of a fire by sealing the ventilation pipe.

The CLVM Clipper Sleeve fixes into position on ceilings and walls with brackets and screws.
