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

    The X-shape fire-retardant zipper is designed for garments and equipment that must open across intersecting directions. When a suit needs access to several internal zones without adding multiple closures, the X-form layout provides a consolidated intersection point that manages all four access routes efficiently.

Four Zones, One Central Point

The X-pattern divides the closure into four functional branches. Each branch serves a different purpose depending on the equipment layout or garment structure:
• Upper branch → chest or hood interface
• Lower branch → torso or utility module access
• Left/Right branches → inspection ports or tool areas

Workers can open a single side, two sides, or create an “X-spread” for broader reach during maintenance or emergency operations.

Fire-Retardant Components for High-Heat Environments

    The zipper uses flame-resistant tape and thermally stable metal teeth. These materials hold their form under exposure to sparks, heat, or radiant energy, ensuring the closure remains functional in conditions common to industrial FR workwear and rescue equipment.

#5 Metal Chain With Cross-Direction Stability

    To handle tension from multiple directions, the teeth are formed to resist twisting and diagonal stress. Whether the garment flexes upward, outward, or across the body, the chain maintains its alignment and locking strength.

Central Junction Operating Logic

    The slider transitions through the intersection smoothly, allowing directional changes without catching. This capability supports complex tasks such as:
• Adjusting breathing apparatus modules
• Opening horizontal access portals
• Reaching internal gear pouches
• Managing multi-layer suits during inspections
• Deploying rescue or utility attachments

One zipper replaces several conventional closures while enhancing maneuverability.

Applications Requiring Multi-Axis Accessibility

The X-form is commonly used in gear where multiple internal zones must be reached quickly:
• Industrial arc-flash or FR suits
• Chemical and biohazard protective layers
• Heavy-duty inspection hoods
• Multi-equipment tactical garments
• Oil & gas field maintenance suits
• Utility and electrical operating gear

• Suitable for Flight Suit, Tactical Coverall

Where garment complexity increases, the X-shape provides clarity and efficiency.

Custom Integration Options

Manufacturers can adapt the X-form to suit specialized garment layouts:
• Slider type (lock / semi-lock / free-run)
• Puller customization
• Tape width & color options
• Reinforced stitching compatibility
• Module-specific shaping for unique garment patterns

Each zipper is produced with strict precision to ensure uniform performance across all four axes.
