3362p trimmers 5 holes on pcb?

[drgonzo1969]

Sorry if this is a dumb question but I’m confused. I have a couple of PCBs in the works and a few of them have 5 holes for the cermet 3362p trim pot but the pot only has 3 legs. Am I using the wrong trim pot? What am I missing here?

It allows for 2 different size trimmers, probably also the 3386, which I've bought a lot of by mistake

The 6 holes allow for box-style cermet trimmers (such as the 3362p), the wirey open-style trimmers, and straight multi-turn precision trimmers like the 3296W
