This quality door holder is constructed from 304 grade Brushed Satin Stainless Steel finish. It features a spring loaded plunger with a 1" throw and a large soft rubber foot for good holding power. The plunger also has an internal rubber bumper for a quieter operation when retracting. This holder works best when it is installed on the frame side of the door so that the door pushes against the holder when trying to close. Includes four stainless steel mounting screws.
