Where layouts change week to week, a screw-mounted barrier ends up in the wrong place; this one moves with the work. The powerful magnet back plate attaches the housing to any vertical metal surface, and because the belt end is also magnetic, no wall receptacle is needed. The belt connects directly to metal on the opposite side of a machine bay, a racking aisle, or a temporary maintenance zone. Inside the housing, a viscous-damping belt-braking mechanism is designed for slow, controlled retraction and can be replaced in the field with a screwdriver. Built on the patented Beltrac® design (USPTO No. 2,472,720), the unit carries a Wrinkle Black (WB) finish with a Black (BK) belt. SKU 50-3010MG/WB/BK.
