ABSTRACT:
An improved door closer is provided which has a back checking arrangement including a loosely held resilient cushion bar which is engaged by a metallic shield abutting sliding cam plates during a final few degrees of opening of a door to provide an increasing resistance against further opening of the door. The shield preferably engages the cushion bar approximately 4.degree. prior to a normal full open position of the door. Selective thickness of the cushion bar provides either a 90.degree. full open position of the door or a 150.degree. full open position of the door without additional adjustment.
