Beltrac 3000 posts with mid-mechanism are 48" tall, the perfect height for mounting the Instant Hand Sanitizing Dispenser. In addition, these posts also have a mid-mechanism at the 40" height, so it lines up perfectly with other standard Beltrac 3000 stanchions. Each post contains 4 dovetail grooves designed to function as imbedded receivers for additional retractable belts or other attachments such as sign frames. To protect flooring in the queuing line, all posts come with a standard non-marking rubberized base.
