Whether in workshops, shopping malls, offices or restaurants, PUK cable trays can conduct a wide variety of cable types safely along ceilings and walls. The large selection of materials and surface finishes means they can be used in a variety of ways, both indoors and outdoors. PUK cable trays are an integrated, highly flexible cable support system when used in combination with the matching support structures, covers and system-specific accessories. They are available in perforated (RG) or non-perforated (R) versions, in heavy-duty versions (RS/RGS), for use under sprinkler systems (RGL) or as installation cable trays (RI/RIS).
