Litt Industries The Stud Solid Mount Lock N Ride Tie Down Anchor System for Polaris RZR (2 Pack)

these anchors are by far the best ive tried, the mount doesnt fall out when undoing the knob, they fit perfectly. need a few more to replace the expanding rubber ones.

Great product. Way better than the lock and ride style plugs

Allen isn’t long enough, doesn’t pull tight
