Ready for a flush help point.
Lifts, car-park lobbies, disabled toilets and reception counters: wherever an E20S is going in, build this box into the wall and run the PoE cable to it.

Fit
Made for the E20S faceplate.
The E20S is 100 × 100 × 37.7 mm, flush-mounted, and Akuvox designs it for 86-type single in-wall boxes. Its faceplate covers the box completely.
The box has knock-out cable entries for the network cable.
Install
Two screws and it’s done.
Run the PoE cable into the box and plug it into the E20S. Push the panel into the box and fix it with two tamper-proof screws using the Torx wrench supplied with the E20S.
The E20S comes with both M3.5×30 and M4×30 tamper-proof screws, so it also fits existing 86 boxes with different screw sizes.
