Protect That New Playfield!
Designed to protect your playfield from post gouging, these soft, flexible, 100% silicone washers are practically invisible when installed. The grip of the silicone keeps the post where it was meant to be and prevents movement that leads to playfield chipping. The washers are .060" tall, and compress to about half of their thickness so the contact point of the ball will not be affected.
These will squish out from under the post when you tighten them. Try to keep them as centered on the post as possible. These are intended for only plastic posts. If they squirt out too much on one side, loosen, re-center and try again. You will not need to tighten the post quite as much as you would if you were using nothing at all.
