Retracted piston type closer cylinder for intake doors.
Known to work with bottom hinged intake doors by Wilkinson Hi-Rise and US Chutes (US Chutes part ID-07).
Includes one (1) #NRHK hardware kit (bracket, pins, etc).
HOW TO MEASURE CLOSER CYLINDERS: Measure cylinder housing only; actual length will be close but not exact to length per description.
MFG ID: The intake door manufacturer name is usually along the bottom of the UL label affixed to the intake door - the label is usually found on an edge of the intake door itself (e.g. on the part of the intake door that opens and closes). We will contact you if MFG ID is necessary to complete your order and you do not provide same.
