The TDC MK II can be installed at the time of blown fibre tube cable installation (day one) or fitted over an already installed cable as a retro fit allowing ultimate flexibility for your blown fibre/duct network. The closure offers protection to the accessed tubes and connectors and contains an integral pressure relief valve to prevent accidental over-pressurisation. The product is supplied with a base, cover complete with toggle clips for closing and a pressure relief valve. Rubber seals to seal the in-line cables/ducts are sold separately to suit the required diameter of the cable. Cable glands to distribute the drop cables are supplied separately as required.
