3M 7000002125 Dual Lock Reclosable Fastener SJ3560 Clear

Product Description

The 3M 7000002125 is a reclosable fastener sold under the Dual Lock SJ3560 product line, featuring a clear polypropylene fastener backing with a clear acrylic pressure-sensitive adhesive. It delivers 250 stems per square inch and an engaged thickness of 0.23 inches, producing a strong mechanical closure suited for repeated service. Rated for up to 1,000 open-and-close cycles and capable of operating at temperatures up to 220 degrees F, this fastener is built for demanding applications in both indoor and outdoor environments. Licensed HVAC technicians, electricians, plumbers, and industrial tradespeople use it wherever a durable, tool-free reclosable bond is required.

This fastener is suited for use on metals including aluminum and stainless steel, glass, and high surface energy plastics such as acrylic, polycarbonate, and ABS. Common applications include securing access panels, wire management covers, instrumentation housings, and equipment enclosures where frequent access is needed without fasteners or hardware. The roll format — 6 inches wide by 50 yards — allows the installer to cut custom lengths on site, reducing waste and simplifying fitment across varied surface dimensions.

Key Features

• 250 stems per square inch for high-cycle mechanical closure strength
• Up to 1,000 open-and-close cycles for long service life
• Rated to 220 degrees F for high-temperature environments
• Clear acrylic adhesive bonds to metals, glass, and high surface energy plastics
• Clear polypropylene construction for low-profile, unobtrusive installation
• Roll format (6 inches x 50 yards) allows field-cut custom lengths

Compatibility

Designed for bonding to metals (aluminum, stainless steel), glass, and high surface energy plastics including acrylic, polycarbonate, and ABS surfaces, for both indoor and outdoor use.

Installation Notes

Surface preparation is critical — clean and degrease all bonding surfaces before applying the adhesive backing to ensure full contact and maximum adhesion. Apply firm, even pressure across the full fastener area after positioning. Allow adequate dwell time before loading the bond per standard adhesive application practice. When used in electrical or HVAC enclosures, verify that the fastener material and adhesive are compatible with the thermal environment prior to installation.
