This is a 8 Inch Extended Hydraulic Closer kit that suits both bottom and side hinged chute intake doors. This closure can be used for both Trash and Laundry doors.
The cylinder shaft measures 8″ long. This shock has a 1″ diameter on the thicker part of the cylinder. The thin rod diameter measures 5/16″ in total width. The thin part of the rod when completely extended measures 4-3/4” alone. When you measure it from one pin to the other pin fitting, it measures a total of 12-13/16″ when fully extended.
This 8′ extended piston includes all the parts in the photograph.
This closer is most often used with Wilkinson Chutes, and US Chutes (ID-06E) intake doors, but can be used with other manufactured doors as well.
