Review on JQuad Pack Trailer Ramp Bumper by Bam Reeder

Worked great for my needs. They do not have built-in steel washers. The center will be crushed under the torque of the screw. It is recommended to use a wing washer with a screw and some blue paint on the screw with a light torque. I put it on a Homda Acty mini truck to prevent the sides of the pull down bed from hitting the wheels when lowered. I used a 3/8" screw. Screw with washer in rivet. I used a sheet metal rivet. Good quality rubber.
