3M 7000052230 Hook Fastener 3/4 in X 50 Yd Black SJ3519FR

Product Description

The 3M 7000052230 is a flame resistant reclosable hook fastener sold in a 3/4-inch-wide by 50-yard roll. Constructed from woven nylon with a synthetic rubber-based adhesive backing, it is engineered to meet the F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test standard. The hook side mates with the 3M SJ3518FR loop fastener to form a secure, reclosable bond. Licensed HVAC, aerospace, and industrial maintenance technicians install this fastener in applications where flame resistance is a code or regulatory requirement. The rubber adhesive delivers reliable high-temperature performance across a broad range of substrate types.

This fastener is suited for use in aerospace interiors, commercial HVAC equipment enclosures, electrical panel applications, and any installation environment that demands a flame resistant reclosable attachment solution. It bonds effectively to paper, cardboard, painted and bare metal, glass, sealed wood, and many rigid plastics. The roll format allows field cutting to length, making it practical for both large installation runs and smaller repair or retrofit work.

Key Features

• Meets F.A.R. 25.853 paragraph (a)(1)(i) 60-second vertical burn test for flame resistance
• Woven nylon hook construction for durable, repeated open-and-close cycles
• Flame resistant synthetic rubber adhesive for high-temperature performance
• Mates with 3M SJ3518FR loop fastener for a complete reclosable system
• Adheres to metal, glass, painted surfaces, sealed wood, and many plastics
• 50-yard roll length minimizes splices on longer installation runs

Compatibility

Designed to mate with the 3M SJ3518FR flame resistant loop fastener as part of a reclosable hook-and-loop fastening system.

Installation Notes

Surface preparation is critical before application — clean the substrate thoroughly to remove dust, oil, and moisture to ensure full adhesive contact. Apply firm pressure along the full length of the fastener strip after placement to activate the adhesive bond. Allow adequate dwell time before loading the joint. Minimum order quantity is 4 rolls per order.
