SPIFR #5 Metal Fire Retardant Two Way Open Zipper

    This two-way open-end zipper is suited for protective garments requiring top-down and bottom-up opening paths. With two independent sliders, the wearer can adjust ventilation, access tools, or detach the garment from either direction, improving mobility in heat-intensive or high-risk environments.

Independent Dual-Slider Operation

Each slider functions separately, allowing multiple opening modes:
• Open from the top for quick chest access
• Open from the bottom for mobility adjustment
• Create a central gap for airflow or equipment reach
• Fully detach using the open-end bottom structure

Workers can adapt the opening direction based on task requirements without removing gloves or disrupting protective layering.

Flame-Retardant Tape With Heat-Stable Metal Chain

    Both the textile tape and metal components are formulated to maintain stability under heat exposure. The zipper resists melting or warping when subjected to sparks, radiant heat, or brief contact with flame—ideal for fire-retardant and industrial protective outerwear.

#5 Metal Teeth Designed for Repeated Bi-Directional Use

    The metal chain withstands the additional stress caused by two sliders moving in opposite directions. Teeth remain aligned even when the garment bends, stretches, or is partially opened from both ends. This ensures a reliable, secure closure throughout long shifts.

Smooth Tracking & Controlled Handling

    The sliders run with consistent motion and predictable resistance. Locking options prevent unintended movement during climbing, lifting, kneeling, or tool operations. This makes the zipper practical for:
• FR jackets and coveralls
• Industrial suits requiring variable ventilation
• Emergency response outerwear
• Protective equipment panels or detachable modules
• Tactical garments with adjustable access points

Optimized for Field Work & Industrial Safety Gear

This two-way FR zipper is frequently used in:
• Oil & gas field operations
• Fire-retardant industrial apparel
• Utility and electrical maintenance work
• Rescue and emergency response uniforms
• Mechanical and chemical facility wear

Personnel benefit from a closure that adapts instantly to their movement and task environment.

Custom Manufacturing Options

Available in multiple specifications to support OEM integration:
• Length and tape, teeth color variations
• Slider options: auto-lock / non-lock / semi-lock
• Puller customization for gloves or tool handling
• Optional heavy-duty bottom stop assembly

    Each zipper undergoes dimensional control to ensure dependable performance in demanding field applications.
