Potentiometer - Peavey, Linear, Spider

Question:
Is the 4th leg just a support, or is it connected to a second wiper? Trying to replace a busted one that has 4 connections - the usual 3, and a 4th one at 12 o’clock. Never seen one like it.

Answer:
The 4th leg is not connected on these and is only used for support.
