SUB-DUCT ANCHOR
The telephone network from the telephone exchange up to the customer's premises needs to be protected against water, sediments, and unwanted objects.
Our Sub-Duct Anchors/Plugs are designed for sealing cables and inner ducts in telephone networks. These anchors are made of specially compounded rubber to ensure flexibility and sealing performance. Expansion of the anchor/plug is achieved by compressing the rubber between metallic washers. All metallic parts are made from galvanised steel, with stainless steel options available upon request.
