The PostMaster 68 (PM68) spade is the newest addition to our connector line. It features a dual width opening making it compatible with both 1/4" and 5/16" binding posts. The ridges ensure focused contact pressure and reduce contact resistance. Manufactured from pure copper and available with either Electroless Nickel plating or no plating. The PM68 is now our preferred spade connector option for our PR, TC and Carbon speaker cables. Its design also allows it to be used as an adapter with most banana connectors allowing for a spade connection.
