Well designed and sturdy, this Australian-made gate stop will prolong the life of your gate. Manufactured from heavy-duty UV-resistant glass-fiber nylon, it has an integral rubber bumper to prevent the gate from over-closing, while dampening any associated noise. Measures 4 3/4" high and mounts with #12 screws (not included). Two stops are recommended for gates over 4' (1200mm). Maintenance free, it has a lifetime warranty.
