SPIFR #5 Metal Fire Retardant Open End (O/E) Zipper

    This open-end fire-retardant zipper is developed for protective garments that must be opened fully from the hem upward. When a suit, jacket, or panel needs quick release and direct access, the O/E configuration provides a clean separation point with dependable reconnect capability.

Reliable Performance Under Heat Exposure
    The tape is made from flame-resistant materials, and the metal chain is stabilized to endure elevated temperature environments. The zipper maintains its form when exposed to sparks, radiant heat, or intermittent flame, ensuring that the garment barrier remains secure during use.

Full Detach Bottom Design
    The lower pin-and-box set allows the two sides of the zipper to disengage completely. Workers can step in or exit the garment quickly, even when wearing gloves or equipment. This design is widely used in FR jackets, protective coveralls, and high-mobility outerwear.

Consistent Chain Strength With #5 Metal Teeth
    The metal teeth provide firm bite strength and resist distortion during repeated engagement. Whether the garment is under tension, movement, or bending, the chain stays aligned and locks smoothly upon pull-up.

Controlled Slider Operation
    The slider tracks evenly with minimal resistance, offering predictable handling in industrial settings. Locking options help prevent accidental opening when the wearer lifts, bends, or performs repetitive tasks.

Suitable for Demanding Work Environments
This zipper supports garments used in:
• Oil & gas operations
• Fire-retardant industrial outerwear
• Electrical and utility work
• Emergency response clothing
• Chemical-related handling zones
• Tactical and field-service uniforms

    Personnel working around heat, arc-flash sources, or volatile materials benefit from a closure that remains stable yet easy to operate.
