Quoted from Mr_Tantrum:
Don't know if everyone is aware of these lockbar rail decals, but next time you order rings/rubbers, you should consider them. Not that they are necessary (then again, that can be said for many things we put on our pins), but it they do give an improved appearance every time you lift the playfield for maintenance. I have them on both my pins, and for some reason the nice finished look just makes me feel better than looking at the old tarnished/rusted piece of metal with missing/tattered stickers on it.
I have one in my cart. Can you post a pic of yours installed?
