Socket Mounting Box with Adaptor
Ideal for both power and data outlets where more depth may be required for the fittings and cables. The 25mm depth surface mounting boxes allow 16×16 and 25×16mm trunking to be neatly secured to the boxes via the supplied manifold adaptor, which also allows the box to be mounted flush to the side of door architrave or fitted at floor or skirting board level.
