An enclosure or rack for use in a telecommunications or data communications network includes an upper frame assembly 1 and a lower frame assembly 2. Four upright frame members (3,4,5,6) are connectible between the frame assemblies in a plurality of different positions along the sides of the frame assemblies to provide different configurations for the enclosure and upright mounting angles (23,24,25,26) on which communications equipment is mounted. The configurations include, at least, a first configuration with the frame members in the corners of the frame (fig 1a) and a second configuration with the frame members spaced apart from the corners (see fig 2b)
