Secure mounting of category 5E couplers has never been better. L-com's exclusive flange mount couplers pre-installed into standard 19" rack panels provide the best method for coupling up to 32 category 5E grade patch cables on a rack. The metal flange is attached permanently to the panel with two 4-40 screws. Panels have a black powder coat finish for durability and each port is numbered to simplify cable organization and tracking. Both shielded and non-shielded versions are offered to fit individual applications.
