Abstract
A non-rotatable pinion cap for use on a non-handed door closer where both ends of the drive pinion extend beyond the cylinder body. The pinion cap has one exposed edge for engaging the door or door frame surface and includes a christmas tree plug for attaching the pinion cap to a threaded hole in one end of the drive pinion. The plug can either be free to rotate with the pinion or it can be fixed to the cap. The slippage of the plug permits the drive pinion to rotate while the pinion cap does not rotate.
