3M 7000051777 Flame Resistant Loop Fastener 2in X 50yd Beige

Product Description

The 3M 7000051777 is a flame resistant, no-adhesive nylon woven loop reclosable fastener sold in a 2-inch-wide by 50-yard roll in beige. It carries an engaged thickness of 0.15 inches and is rated to withstand temperatures up to 250 degrees F. The SJ3418FR meets the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test, making it suitable for applications where fire resistance is a regulatory requirement. It is designed to mate with the SJ3419FR hook fastener. Installers and fabricators working with flame-rated assemblies rely on this fastener for adjustable, reclosable closures that maintain compliance without adding adhesive.

This loop fastener is intended for use in garment, textile, and fabric applications where a clean, tailored appearance is required alongside flame resistance compliance. Common use cases include aircraft interior panels, protective apparel, and other soft-goods assemblies subject to fire-safety standards. The roll format simplifies cut-to-length installation in production or field environments. Because the product is preshrunk, it maintains dimensional stability and flatness after repeated wash or dry-clean cycles.

Key Features

• Flame resistant construction meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test

• Temperature resistance up to 250 degrees F
• Engaged thickness of 0.15 inches for a low-profile, flush fit
• Preshrunk nylon weave for maximum dimensional stability and flatness
• Washable and dry cleanable for reusable or launderable assemblies

Compatibility

Designed to mate with the 3M SJ3419FR flame resistant hook fastener as a matched hook-and-loop pair.

Installation Notes

This fastener is typically installed by fabricators, seamstresses, or assembly technicians working with textiles and soft-goods. No adhesive activation is required — the loop material is sewn or otherwise mechanically attached to the substrate. Ensure mating surfaces are clean and dry before engagement. Follow all applicable fire-safety and airworthiness regulations governing the end-use assembly.
