Socket Box Covers

Tenmat’s Socket Box Covers (SBC) are manufactured from halogen-free, low-smoke, intumescent mineral fibre material and are designed to reinstate the fire performance of partition (stud) wall constructions when penetrated by steel or plastic electrical socket back boxes.

Socket Box Covers

Effective fire performance for socket boxes

The cover will also provide resistance to the passage of sound and air movement.

In the event of a fire the Socket Box Covers (SBC) intumescent material will expand to enclose the electrical back box and cables, providing effective fire resistance, for integrity and insulation for 60 or 120 minutes depending upon the partition (stud) wall construction.
