National Mfg N100-039 Heavy Duty Door Closer

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N100-039 is a heavy duty, air-controlled door closer designed for out-swinging wood or metal doors. It regulates closing speed and force through an air-control mechanism, giving installers precise adjustment capability in the field. The unit ships in white finish and is permanently lubricated for extended service life without routine maintenance. A 2-hole end plug allows the closing force to be set to match the door weight and traffic frequency. This type of hardware is typically installed by carpenters, general contractors, or maintenance technicians on commercial and residential entry doors.

The N100-039 is suited for out-swinging doors up to 1-3/8 inches thick, covering a wide range of standard wood and hollow-metal door applications. The fully adjustable closing speed makes it a practical choice for high-traffic entryways where consistent, controlled door return is required. A hold-open washer is included, allowing the door to be held in the open position when needed without additional hardware. This unit is packaged in a quantity of 3, making it efficient for multi-door installations or stocking purposes.
