19" shelf, front mounting only, 300mm depth, black This equipment shelf is designed exclusively for mounting on the front 483 mm (19" inch) profile rails. This means that the installation is no longer dependent on the distance between the front and rear profiles. It is ideal for all 19" cabinets from a depth of 450 mm - regardless of whether it is a free-standing or wall-mounted cabinet. The robust steel construction ensures a high load-bearing capacity.
