Rockymounts hitch bike rack install question

just installed a rockymounts splitrail hitch bike rack. Was wondering if anyone else had issues getting the wedge square piece to insert into the hitch receiver to help with eliminating some of the movement.

The hitch goes into the receiver with some play but not enough where there is enough room to get the wedge piece to fit in there as well. So just tightened the piece on there but not really serving the function it was intended for.

The rack seemed fine on a short trip so not a big issue. Just more curious than concerned.

Thanks.

 

I'm about to install one. I'll let you know. Did you have any issues with the gate hitting the rack when folding it down? Thanks.
