Pinball kickout hole protector; Williams smaller diameter

Kickout hole protector for Williams Pinball games with the 1 1/4" diameter kickout hole. Measure your hole diameter to choose correct size protector.
The slot is for clearing the two metal posts and the kickout pawl. I show it installed in a playfield but I have not used it with the metal posts or mechanism.
It will need to be fastened in the hole using a temporary adhesive such as a little bit of RTV.
These are replaceable if they wear out so don't permanently glue it in place.
