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

    The X-shape FR zipper is built for garments and equipment that need access points branching in four directions. This configuration is ideal for protective suits, ventilation modules, and functional panels where multiple entry axes are required without adding separate zippers.

Four-Way Opening Layout for Complex Work Zones

    The X-form layout creates a central junction where the slider can move toward any of the four arms. This structure reduces the need for additional closures and allows quick access to internal layers, tools, or integrated equipment modules.

Technicians can open a single arm, opposite arms, or create a cross-shaped opening depending on operational needs.

FR Tape & Heat-Stable Metal Components

    The flame-retardant tape maintains stability when exposed to high temperatures. The metal teeth resist heat distortion, making the zipper suitable for environments where sparks, radiant heat, or intermittent flame are present.

The closure remains intact even under sustained bending or tension during complex tasks.

#5 Metal Teeth With Cross-Directional Strength

    The metal chain is reinforced for directional force from multiple angles:
• Vertical pulling
• Horizontal tension
• Diagonal twisting from panel movement

This ensures consistent engagement no matter how the garment or equipment stretches during work.

Central Slider Node for Smooth Direction Switching

    At the intersection, the slider transitions between arms without snagging. Workers can redirect the opening path with a single hand, making the zipper practical for:
• Multi-layer protective suits
• Breathing apparatus integration points
• Tool access windows
• Inspection ports on industrial hoods or outer shells
• Tactical garments requiring quick branching access

Applications in Demanding Work Conditions

    The X-form zipper supports protective systems used in environments such as:
• Fire-retardant industrial suits
• Chemical and biohazard operations
• Oil & gas maintenance work
• Field rescue and emergency response
• Utility and electrical operations
• Tactical and mission-specific uniforms

    Where multiple access directions are required, this closure provides a compact, efficient solution.

Custom Production Options

    Manufacturing variations can be aligned to OEM integration needs:
• Slider selection: auto-lock, semi-lock, non-lock
• Puller shape modifications
• Tape width & color options
• Heavy-duty stitching compatibility
• Optional sealed cover or panel integration

    Each zipper is produced with precise dimensional control to ensure stable alignment across all four branches.
