3M 7000051839 Flame Resistant Loop Fastener 3/4 in X 50 Yd

Product Description

The 3M 7000051839 is a flame resistant, woven nylon loop reclosable fastener designed for applications where fire safety and reliable closure are required. Sold in a 3/4-inch-wide by 50-yard roll in black, this no-adhesive loop fastener mates with the 3M SJ3419FR hook fastener to create a secure, reclosable system. It carries an engaged thickness of 0.15 inches and is rated temperature resistant to 250 degrees F. The product meets F.A.R. 25.853 paragraph (a)(1)(i), the 60-second vertical burn test standard used in aerospace and transportation applications. Installation requires no adhesive backing, relying instead on the woven loop structure to mate with a compatible hook fastener.

This fastener is suited for garment, fabric, and soft-goods applications where a tailored appearance and reclosable functionality are needed. Its preshrunk construction maintains dimensional stability and flatness after repeated wash and dry-clean cycles, making it a practical choice for professional garment manufacturing, protective apparel, and flame-rated textile assemblies. Typical users include industrial garment manufacturers, upholstery professionals, and aerospace interior fabricators working with flame-rated materials.
