Secure mounting of category 5e couplers has never been better. L-com’s exclusive flange mount shielded couplers pre-installed into standard 19″ rack panels provide the best method for coupling up to 16 category 5e grade patch cables on a rack. The metal flange is attached permanently to the panel with two 4-40 screws. The shielded couplers provide protection against unwanted EMI/RFI emissions. Panels have a black powder coat finish for durability and each port is numbered to simplify cable organization and tracking.
