3M 7010340891 Dual Lock Reclosable Fastener SJ3560 Clear

Product Description

The 3M 7010340891 is a clear reclosable fastener strip sold as the SJ3560 Dual Lock Reclosable Fastener, designed for secure, tool-free mechanical attachment in industrial, commercial, and field-service applications. The fastener features a clear polypropylene mushroom-stem surface with 250 stems per square inch and an engaged thickness of 0.23 inches. A clear acrylic pressure-sensitive adhesive on the back bonds directly to the substrate on application. The roll measures 3 inches wide by 50 yards long, providing enough material for large-scale or repetitive installs. Rated for up to 220 degrees F, the SJ3560 holds in both indoor and outdoor environments. Closure life is rated at 1,000 open-and-close cycles.

This fastener is suited for attaching panels, covers, cable runs, signs, and equipment housings to metal frames or rigid plastic enclosures. Common applications include HVAC duct panel retention, electrical enclosure cover fastening, equipment labeling, and general maintenance access panels where repeated removal is required. It adheres well to metals such as aluminum and stainless steel, glass, and high surface energy plastics including acrylic, polycarbonate, and ABS. The 50-yard roll format supports production or multi-unit installs where consistent strip-length cutting is practical.

Key Features

• 250 stems per square inch for high-engagement holding strength across the bonded surface
• Clear acrylic pressure-sensitive adhesive backing bonds to metal, glass, and high surface energy plastics
• Rated to 220 degrees F for use in high-temperature indoor and outdoor environments
• 1,000-cycle closure life supports frequent access panel or cover removal
• 0.23-inch engaged thickness for low-profile mechanical fastening
• 3-inch wide by 50-yard roll format for field cutting to any required length

Compatibility

Designed for bonding to metals including aluminum and stainless steel, glass, and high surface energy plastics such as acrylic, polycarbonate, and ABS. Not recommended for low surface energy plastics or untreated polyolefin substrates.

Installation Notes

Surface preparation is critical before applying the adhesive-backed fastener strip. Clean the substrate thoroughly to remove oils, dust, and moisture before pressing the adhesive firmly into contact. Allow adequate dwell time at room temperature before loading the joint. Cutting to length with a sharp utility knife or scissors produces clean edges that maintain full adhesive contact along the strip width.
