Yes, as far as I can tell, the screws go into an embedded aluminum plate as the rest of the gear is attached like the traveler, etc. In other words, the backing plate is actually an embedded piece in the FRP. In other words, no piece on the other side since it's embedded. Hope that makes sense. I would imagine the plate was there on all the constructions to add the rig as a dealer-installed accessory. But, I don't know enough to confirm that. You could check with the Hunter guys for a few dollars on this site.
