WeatherMaster Twin offers improved perimeter security as its lower belt restricts pedestrians from ducking under the belt. The bottom belt also makes this stanchion ADA (Americans with Disabilities Act) compliant. This post features a unique two-piece post construction which allows the lower belt mechanism to be easily replaced in the field. WeatherMaster 250 is designed for restricting access in tough outdoor environments. Manufactured with a stainless-steel post and a heavy-duty rubber base there is nothing to rust. The base features convenient carry handles, a curved design to reduce trip hazard and is and is tough enough to drive over. All WeatherMaster models feature a braking system for slow, safe belt retraction and a locking belt end to prevent accidental release.
