6" Intake Door Closer Kit For Side Hinged Intake Doors

HOW TO MEASURE CLOSER CYLINDERS: Measure cylinder housing only; actual length will be close but not exact to length per description.

HOW TO DETERMINE HINGE SIDE: Hinge side is whichever side the door hinge is located (on the left or right) when looking at intake door on wall.

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.
