The Gorila Jammers arms are built tough! This is the longer version but we also made a compact version to fit inside your rack.

Each arms are rotating on two Oilite® bushings for a smooth and non wobbly movement. We've used hitchpins everywhere so that every components are easy and quick to move, including the arms. The Gorila Jammer Arms feature recylced HDPE plastic on every surface to protect your rack from scratches. A thick rubber bumper also prevents the lever arm from touching the rack and reduces system noise. The handle design will give you just the right amount of options and can be mounted/dismounted in seconds.
