Chrome Single Rail Classic Rolling Collapsible Clothing Rack ("Salesman Rack", all square tubing) Style - Classically styled to blend into any store theme. Hanging Space - the single rail gives up to 48 inches of hanging space (minus the area used for the support poles use). Salesman Rack - this classic rack was designed with salesmen in mind as they are built for transport. This particular model is designed to collapse easily for storage and transport (and does not actually 'fold up' as our other salesman model does). Salesman or not, these racks are the perfect versatile merchandising rack for any retail environment. Base - the wide base gives this rack the sturdiness it needs to withstand customer traffic. Rolling - four 4" wheels (casters) attached to bottom allow for smooth rolling. There are no locking mechanisms on the wheels.
