Hello every time I get a new Stern pinball I always immediately spend $80 to buy and ship new rails with built in button protectors.
Then I have to take off the old rails and install the new ones, hoping I don't accidentally drop the rail while taking it off and scratch my side art and then waste all that original metal from the original rails as I have no need for them.
Anyway I got tired of doing that and designed a cheap and super easy to use replacement, no need to remove the old rails, and NO need to drill holes!
or save some money and buy 3 at a time!
