The 4181US Duplex Power Outlet features Beryllium Copper contacts, plated with Rhodium over Silver, for improved electrical contact and current transfer. Amazing grip tension provides solid contact and superb plug retention on the heaviest of cables. In our opinion, this Audio grade outlet represents the best price to performance ratio on the market today. The top & bottom outlet can be electrically joined (as with a standard duplex), or completely isolated from each other. This flexibility extends to the Ground circuit as well.
