National Mfg N100-033 Medium Duty Door Closer White

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N100-033 is a medium-duty, air-controlled door closer designed for out-swinging wood or metal doors up to 1-3/8 inches thick. It delivers fully adjustable closing speed, letting installers dial in the right response for the application without swapping components. A 2-hole end plug allows on-site regulation of closing force. The unit ships with a hold-open washer for added convenience. Because the closer is permanently lubricated at the factory, it requires no field lubrication and is built for extended service life. Finished in white, it suits residential and light commercial door frames where a clean appearance is needed alongside reliable function.

This door closer is intended for out-swinging wood or metal doors in residential and light commercial settings. Typical installations include exterior entry doors, storm doors, and utility room doors where controlled, automatic closing is required. The air-controlled mechanism provides smooth, consistent closure without the need for hydraulic fluid, making it a practical choice for environments where maintenance access is limited. Installers working on standard 1-3/8-inch thick door slabs will find this unit fits within common retrofit and new-installation scenarios.
