The lower belt is the point. It sits within the sweep of a cane, so a visually impaired guest finds the edge of the lane the same way everyone else sees it. Both belts pull out together and clip to the next post, so setting an accessible line takes no longer than setting a standard one. Under the post is a weighted base you choose for the floor: 14-inch sloped, 14.5-inch slim, 12-inch rounded, square, heavy sloped, or galvanized for outdoor runs. The post keeps every Beltrac 3000 feature, including the 4-way dovetail grooves for signs and NeXtrac fixtures and the field-replaceable belt mechanism. Built in the USA, 5-year post warranty. Ships assembled or knockdown.
