Clamp for mounting the wooden skirting boards, made of black plastic. It consists of two pieces: a rectangular piece with two rails and a clamping clip. The rectangular piece can be separated to use one or the other rail, as required. One of the rails allows for installation with screw, directly to the plinth. The other rail allows a direct coupling through a groove pre-drilled in the socket 6 mm deep and 4.2 mm thick. Once the rail is in place, the clamp is slid through it and attached to the bone foot of the module. The packaging presentation is 200 units.
