Anyone upgrade Frag Rack to Locking Frag Rack?

[West1]

I’ve got a few frag racks and I’m getting tired of reaching in the back of my 525xl to place knocked over frags back in the rack. I know others with Acros share the same frustration!

Anyone mod one so it’s got a diy locking mechanism? What material did you use if so?

My frags say THANK YOU!

There are rocks with a layer of rubber sandwiched between two acrylic sheets, at the site of frag holes u get extensions of the rubber which are sliced and protruding a bit in the whole, this makes adapting to different frag plug tips easy and causes a bit of resistance when pulling frags out.

Do you know what type of rubber? Assuming there’s different types of rubber.
I do plan to buy future frag racks w/locking system, just want to upgrade the ones I have.
