1" (25 mm) diameter tube is 61" (1.5 m) long to fit doors up to 60" (1.5 m) wide. Closer mounts above the screen door with two screws into the wall, and includes a bracket that attaches to the screen door with two additional screws, all supplied. Diecast end caps, and a ball bearing pulley wheel give smooth operation. End cap has an air relief screw to adjust closing speed. For existing screen doors that do not roll freely, two 1-1/4" (32 mm) diameter concave roller bearings are included in the kit, as well as a top guide. Not all doors are designed to use these parts. New original equipment rollers may need to be installed to make the door roll properly. Important Notes: Designed for Residential Sliding Screen Door Applications, not for heavy-duty commercial or institutional applications.
