Connection terminal adapters enable the connection of banana plugs, multi-pole connectors, bare wires and cable eyelets. Banana plugs are plugged into the open end of the connector. Multi-pin connectors and bare wires are pushed into the opening on the underside of the adapter and secured with the screw. Cable eyelets are placed around the metal pin and clamped in place. The adapter is 3 inches in diameter and 2 inches high including the connection. The rubberized aluminum base prevents it from slipping.
