Work great on sheet metal, body panels, glass, granite, tile & more; also available in 3-in.
Set of 2 suction handles, tested to lift up to 75 lbs each (see description)
For best results, use on clean, flat surfaces with smooth finish. Objects with textured, brushed or satin finishes or surface variations degrade the air-tightness of vacuum seal reducing lift capacity. Pulling/lifting at angle other-than 90-degrees from surface also affects performance. In our tests, the cups were placed on flat 18-ga sheet metal with semi-gloss finish and lift was applied at 90-degrees until cups broke free - consistently requiring more than 75 lbs of lift. Coating cup-rim lightly with small amount of vegetable/petroleum oil may improve seal quality on some surfaces.
