[1] All Series 7900 Closers are shipped with a slide treack 25" (635mm) long. For narrower doors a shorter length slide track is required, the track can be cut to the desired length at the time of installation. This provides application versatility and assures the proper length track. [2] The template position for the slide track must always be measured from the centerline of the door's pivot point. [3] An auxiliary door stop is required for all center pivot installations. All dimensions are for reference only. Dimensions in parentheses are millimeters unless noted otherwise. Door sizing information is based on installation on standard weight doors. 7'0" (2.13m) high, 1-3/4: (44mm) thick, hung on pivots and operating under normal conditions.
