Manufactured from hot rolled steel with a triple-protected finish, this spring resists corrosion in demanding outdoor and high-moisture environments. The closing tension is field-adjustable, allowing installers to dial in the right resistance for the specific door or gate weight. At 14 inches, this spring is sized for heavier applications where a shorter spring would not provide adequate closing force. Mounting screws are included for a straightforward installation.\u003c\/p\u003e\n\u003cp\u003eThis spring is suited for residential and light commercial gate and door installations where consistent, automatic closing is required. Typical applications include wooden or metal fence gates, utility doors, and similar access points that must return to a closed position after each use. The adjustable tension feature makes it adaptable across a range of door weights and swing angles. It is commonly installed by fence contractors, general contractors, and experienced DIYers working on perimeter access control or property enclosure projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-closing design automatically returns doors and gates to the closed position\u003c\/li\u003e\n  \u003cli\u003eAdjustable closing tension to match door or gate weight\u003c\/li\u003e\n  \u003cli\u003e14-inch size rated for heavier door and gate applications\u003c\/li\u003e\n  \u003cli\u003eManufactured from hot rolled steel for strength and durability\u003c\/li\u003e\n  \u003cli\u003eTriple-protected finish provides enhanced corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMounting screws included for complete out-of-box installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a self-closing spring for residential and light commercial doors and gates where heavier closing tension is required.
