Up for grabs is an almost new Pneumatic Gate Caster has a spring loaded universal bracket for use on wood or chain link fence. Durable rubber does not develop flat sports under a standing load. 8" (20.3 cm) caster supports weight of gates up to 200 lbs (90.7 kg). I poured my driveway .. so this castor doesn't fit underneath the gate any longer .. it's in as new condition .. half price and save the tax .. how can you say no to this ..
