SPIFR #5 Metal Fire Retardant X Shape(X form)Zipper

Technical Feature Overview

1. X-Geometry Tooth Profile for Controlled Engagement

    The zipper adopts an X-shaped metal tooth profile that distributes mechanical load across four contact points.
This configuration stabilizes the chain during bending, torso rotation, or rapid movement—conditions commonly present in flight and tactical operations.

2. Fire-Retardant Metal Components for Heat-Exposure Scenarios

    All metallic elements undergo fire-retardant processing to slow combustion and minimize flame propagation.
This provides an essential safety buffer for aviation garments and tactical coveralls used around hot surfaces, ignition risks, or emergency heat events.

3. #5 Metal Gauge—Optimized for Structural Durability

    A #5 metal gauge offers a precise balance between tensile strength and operational flexibility.
It withstands long-term mechanical stress from equipment straps, harness friction, and layered garment construction.

4. Low-Deviation Track Alignment

    The X Form tooth arrangement naturally supports linear alignment under stress, reducing the likelihood of chain distortion.
This ensures consistent sliding performance on heavy, multi-layer, or stiff fabrics commonly used in mission uniforms.

5. Operable in Demanding Field Environments

Engineered for garments exposed to:

• High-mobility aviation tasks
