TALES ARABIAN NIGHTS (WMS) Hole Guard
Williams TALES OF THE ARABIAN NIGHTS pinball machine Hole Guard set.
INSTALLATION: You’ll notice the ring will only fit one way due to where the notches are cut. Place a bead of clear silicon around the underside of the ring and press in place. Wipe excess silicon and let dry for 24 hours. The silicon does a couple of things: first it keeps the protector in place and 2nd it absorbs some shock. If the protector comes loose, carefully remove the silicon and repeat process.Reference:
