The Pipeline Collection has been popular since it was introduced. Inspired by the racks seen throughout Manhattan's Garment District, the collection is also made from plumbing pipe and connectors but finished in an attractive and durable anthracite gray epoxy. The circular hangrail is adjustable from 45" to 67" high and allows retailers to display a sizeable amount of merchandise within a very compact footprint on their selling floor- 26" x 26". The uprights and hangrail are made of 1¼"pipe with four 3" casters, two that lock. In addition, the unit comes with four rubber-tipped shelf supports.
