Product title: HEAVY DUTY SUCTION CUP HOOK ~ Set of 3 BLK, each with 22 lb capacity
Product description: The excellent suction power of the Pro Suction Cup Hook creates a strength that can hold up to 22 lbs. of weight; a suction cup is a mobile hanging solution and not meant to be permanent like a nail or screw. * The design gives superior suction adhesion on surfaces with all of the following characteristics: flat, non-porous, glossy, and polished. Its important to follow all instructions to insure that the suction cup performs optimally. Surface examples are shiny subway or porcelain tiles, glass, mirrors, acrylic glass, Plexiglas, fiberglass, baked enamel appliance panels, powder coated metals like file cabinets and machine tool panels, stainless steel, plastics and dry erase boards. * Attachment to natural stones like marble and granite is not recommended since those materials are too porous even though they appear to be non-porous. * The PRO HOOK attaches easily. Firmly press the cup against a cleaned surface to remove air and to create a vacuum bond to the surface. Continue to firmly push towards the surface as and turn the tri-wing nut clockwise until it will no longer rotate. Insert the steel hook in one of three holes. It's a good idea to check the tightness periodically and to tighten the tri-wingnut as needed and described in the instructions to keep a good suction. The suction cup is not a permanent fastener like screws, nails, epoxies and other hardware fasteners. * Alcohol packs are included for cleaning a surface and suction cup before installation to ensure best performance. * The Pro Suction Cup is a composite of plastics, including dimensionally stable Phthalates Free PVC, and powder-coated steel materials that are ROHS Compliant.
