if it helps Pete

James says none of his ramps need to have entrance protectors fitted
and if it helps  I'll give you a replacement guarantee for 24 months from date of purchase on the ES ramps that I just sent you
if you decided not to use protectors 

Greg, I am not complaining about the ramps or your service
I know that Pinball inc states that their ramps are made better than the original
plus that they are new and not brittle from 20+ years of sunlight

I was just curious as to the groups thinking about adding the protectors

As CoT said, maybe it is better to add them and be safe
