A permanent lane should be right for everyone from the first day. The second belt runs low on the post, inside the sweep of a cane, so the edge of the queue is detectable before anyone reaches it. The flange mount keeps that lane exactly as laid out, through years of daily contact. Everything else is Beltrac 3000. The one-piece aluminum post carries 4-way dovetail grooves for sign frames, panels, and NeXtrac fixtures. The belt retracts under a centrifugal brake instead of snapping home, and the mechanism replaces in the field. Built in the USA, with a 5-year post warranty and 3 years on the mechanism.
