Trent can help you out I am sure.
“Plastic Aprons”? Wings?
I can’t think of any plastic parts on my GCIV.
I have drop pockets.
If yours has a ball return then maybe you are describing the short dished pieces that transition from the pocket liner to the main system of return gullies?
I’ve always heard those called “Gully Boots” or Wings.
Classic Billiards has a set for $195.

Valley tables have them, but GC’s use a one piece rubber pocket for their gully system.
So I am not sure.
Trent will know.
I am interested in knowing.
