Each end connects magnetically: the housing's rubber-encased back magnet protects the surface it rests against, and the magnetic belt clip lands on ferrous metal or on one of the two included 3″ adhesive mounting plates. On glass alone, the plates supply the steel. The clip also attaches to Beltrac stanchions, belt receivers, and wall receptacles, so one unit works across mixed mounting situations. The belt is available in a 10 or 15 ft length, in Black (BK) with a Wrinkle Black (WB) housing. This is a temporary access barrier that visually blocks or marks off an opening; it is not a fall-protection or life-safety device and will not physically restrain a person. SKU 10/BK/MG/WB/ME/GM.
