3M 7000051785 Flame Resistant Hook Fastener 2in X 50yd

Product Description

The 3M 7000051785 is a flame resistant hook fastener roll designed for applications where fire resistance is a code or safety requirement. Sold as the SJ3419FR hook component, this roll measures 2 inches wide by 50 yards long with an engaged thickness of 0.15 inches. The black hook material pairs with a compatible loop fastener to create a secure mechanical bond. HVAC, electrical, and general mechanical contractors use hook-and-loop fasteners like this for cable management, panel insulation attachment, duct access door closures, and equipment mounting where repeated removal and reattachment is required.

This fastener roll is suited for commercial and industrial installations where flammability ratings matter. The flame resistant construction makes it appropriate for use in environments subject to fire codes, including HVAC equipment rooms, electrical enclosures, and building mechanical systems. It ships in bulk case quantities of six rolls, making it practical for contractors who need consistent supply across multiple job sites or ongoing service contracts.

Key Features

• Flame resistant construction for fire code-sensitive applications
• Hook-style fastener in black for low-visibility installations
• 2 inches wide by 50 yards per roll for high-yield coverage
• 0.15-inch engaged thickness provides a low-profile mechanical bond
• Sold in cases of 6 rolls for job-site and supply stock efficiency

Compatibility

Designed as a hook-side fastener roll intended for use with a compatible loop-side fastener tape in hook-and-loop fastening systems. Verify loop-side compatibility with the appropriate 3M mating component before installation.

Installation Notes

Surface preparation is critical for adhesive-backed hook fasteners — clean bonding surfaces thoroughly and allow adequate dry time before applying the roll. Follow applicable building and mechanical codes, including NFPA guidelines, when selecting fastener materials for fire-rated assemblies. Cut to length with scissors or a utility knife and press firmly across the full width to ensure full contact adhesion. Allow adequate cure time before applying load or mating the hook and loop surfaces.
