Summary: The Warehouse QuickMount™ Retractable Belt Barrier is a warehouse retractable barrier from Lavi Industries that hooks onto shelving uprights and lifts away to relocate. Hooks on the back plate fit uprights from 1 to 3.5 inches wide. A Standard plate suits uprights with holes 1.5 inches apart; an Adjustable plate covers hole spacings from 1 to 3.5 inches. Lifting the unit up and away releases it with one hand, with no bolts or drilling, and a QuickMount Wall Plate accessory mounts it to a wall. The 18-foot belt's self-attaching S-hook wraps the opposing upright, and 24-foot belts and Standard or Magnetic belt ends are also offered. The 2-pound aluminum case comes in Wrinkle Black, Marine Silver, or Yellow; SKU 50-3016M/WB/18/BK is the black 18-foot unit. It is built in the USA, a visual access barrier rather than an impact-rated guardrail, with the FixedMount™ and Rack-Mount as siblings.
