Orange shoulder tang gets aggressive...

I woulda offered a piece, but youre close enough to the United Blvd outlet

Cut it so it fits between your 'scape front to back and when you stuff it in the sand it comes close to or clears the surface
You'll have to play with it to make it fit. The idea is to get it tight enough to the front and back panes so the 2 tangs cannot sneak through
