Hager claims its new flush-fit consumer units are up to 25% faster to fit in both solid and partition walls.

For partition walls, a flange and frame clamp the unit to the wall. The unit slots into the prepared hole and the integral fixing screws are tightened.

With solid brick walls, the installer refits the flange to the sides of the back box and uses it as a fixing bracket to secure the base unit to the wall. This allows the base unit to be held well away from the edge of the blocks or bricks and the plastering can be levelled to the edge of the base. The front cover can then be fixed from the front.
