MX 4mm Banana Right Angle Male Plug Connector Spring Loaded Stackable Beryllium Copper Pair (MX-1401)

A matched red-and-black pair of right-angle, stackable 4mm banana plugs with spring-loaded cable entry, for a bench test lead that needs both a positive and negative connection at once. Beryllium copper contacts hold up to repeated insertion cycles far better than standard brass.
