yes they do
i just went thru this looking for smooth stainless caps for my crew. the alum checkerplate was making a mess of the rails on my canopy, even with the fat foam stuck in there, and they need constant polishing....
i looked at a whole wack of places online, can't remember where, most had checkerplate
or plastic ones.
this is where i got my stainless, but they have plastic too
