The 3M™ Hook Fastener SJ3526N is a professional-grade reclosable fastening solution designed for industrial and occupational applications.

This makes the 3M™ Hook Fastener SJ3526N an efficient solution for securing fabric to furniture cushions, point-of-purchase displays, signage, and other indoor industrial applications.
