14 Inch Adjustable Door Gate Spring
The National Manufacturing Co. N236-612 V850 is a steel spring designed for residential doors and gates. Its 14 inch length suits standard openings where automatic closing is required. The adjustable tension allows installers to set the closing force for the specific weight of the door or gate. This hardware is sold as a single unit in a satin black finish.
Fits Standard Gate and Door Installations
The spring mounts between the frame and the door or gate leaf using common fasteners. It replaces worn or missing closure hardware on existing openings without modifying the structure. The adjustable mechanism frees the installer from matching a fixed spring rate to the door weight. It is not suited for overhead sectional doors or heavy industrial barriers.
