National Mfg N235-028 Door Gate Spring Size 6 Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N235-028 is a Size 6 zinc door and gate spring designed for residential and light commercial gate and door closure applications. Built from zinc for corrosion resistance, this spring provides reliable automatic return tension to keep doors and gates securely closed after each use. It ships in bulk and is sold per unit, making it a practical choice for contractors stocking hardware for multiple installations. The spring is well-suited for trade professionals handling door, fence, and gate hardware as part of a broader project scope.

This spring is commonly installed on wooden or metal gate frames, screen doors, and utility doors where a self-closing mechanism is required. The Size 6 designation indicates the spring body length class, which determines the tension and travel range appropriate for standard residential gate widths. Contractors, carpenters, and general tradespeople typically specify this type of spring for fence gates, pool enclosure gates, and exterior utility doors requiring code-compliant self-closing hardware.

Key Features

• Zinc construction for corrosion resistance in outdoor and high-moisture environments
• Size 6 spring body for standard residential door and gate applications
• Bulk packaging supports multi-unit installations and contractor stocking
• Automatic closure tension keeps doors and gates shut after each use
• Compact form factor fits standard door and gate spring hardware mounts

Compatibility

Designed as an OEM-style replacement or new-install spring for residential and light commercial doors and gates requiring a Size 6 closure spring.

Installation Notes

Installation is typically performed by a carpenter, fence contractor, or general tradesperson using basic hand tools. Ensure the door or gate frame is structurally sound and properly aligned before mounting the spring. Follow all applicable local building codes for self-closing gate hardware, particularly in pool enclosure applications where self-closing and self-latching requirements may apply. Do not overstretch the spring during installation, as this can reduce service life.
