Tenmat’s Socket Box Inserts, are manufactured from halogen free, low smoke, fire resistant, mineral fibre material and are designed to maintain the fire performance of partition (stud) wall constructions when penetrated by steel or plastic electrical back boxes. The insert will also provide resistance to the passage of sound and air movement.
In the event of a fire the Socket Box Inserts mineral fibre material will prevent the fire passing through the electrical back box aperture, providing effective fire resistance, for integrity (E) and insulation (I) from 30 to 120 minutes (EI30 to EI120) depending upon the wall construction.

Fitting Instructions
-
Fit the electrical back box into the aperture in the wall following the manufacturer’s instructions, ensuring the back box is fitted tightly, gaps between the sides of the back box and the hole cut through the plasterboard must be as small as practicable.
Plastic pattress boxes must sit flush to the face of the wall. Metal back boxes can be flush or recessed (see fire test data table for max. recess depth).
-
Cable Install Options:
Option 1) Pierce a hole, as small as possible, through the Socket Box Insert to allow cable to pass through.
Or
Option 2) Make a small slit in the Socket Box Insert to allow retro fitting around cables. Slit must be as small as possible and should close back up once cables installed. (As long as the slit is closed back up, it does not need to be sealed).
Max 3No. Cables per Socket in min. 100mm thick EI30/60/90/120 partitions.
Max 7No. Cables per Socket in min. 190mm thick EI60 partitions.
-
Fit the Socket Box Insert into the back box and pierce two small holes through the face of the insert in the position required for the face plate fixing screws. Alternatively, the Socket Box Insert can be slit at the screw location point to aid installation around fixing screws.
The flange of the Socket Box Insert should sit in front of outer plasterboard layer in all cases except in Metal Back Boxes in up to 60 Minute Rated Partitions where the Socket Box Insert may be recessed by up to 20mm. The width of the flange of the Socket Box Insert may be trimmed to allow recessed fitting, however the depth of the Socket Box Insert must not be reduced.
- Make the electrical connections as required to the switch/socket cover plate and fit the face plate in the normal manner.
- Any excess insert material visible around the sides of the fitted switch/socket cover plate may be trimmed off.
