Re: Bumper Attachment for Rapid Removal

Drill holes in both at regular intervals and tap the holes in the frame, should make it easy enough to attach with a screwdriver.

This is what we did - purchased steel U channel that fit over our frame (perfectly). Then we drilled holes vertically with the bumpers on and dropped 3/16" quick pins in (bolts work fine - no need to thread or put a nut on, friction will keep them in just fine). This got us our "backing member", and got us within a 1/2 pound of max bumper weight which is where we wanted to be.
