Fla Weir Rubber Stopper Install

[Modawg2k]

I had to get a new rubber stopper for my weir door. I installed one a few years ago but cannot remember how I got this thing to fit. I've tried greasing it up with pool lube and pushing it into the hole but no luck. Any advice?

Usually the weir door pegs are spring-loaded. Mine are.

anyone have an idea? I'm sure many have had to install this rubber stopper in their skimmer, it's a Pentair skimmer if that matters
