3M 7100020027 Dual Lock Reclosable Fastener TB3560 Clear

Product Description

The 3M 7100020027 is a Dual Lock Reclosable Fastener in the TB3560 series, featuring a clear polypropylene mushroom-stem construction backed with a clear acrylic pressure-sensitive adhesive. Each side carries 250 stems per square inch, producing a firm mechanical closure without hooks or loops. Engaged thickness is 0.23 inches. The fastener is rated for a closure life of 1,000 cycles and withstands temperatures up to 220 degrees F, making it suitable for demanding thermal environments. HVAC, electrical, and general trade technicians use this fastener to secure panels, wire looms, cable runs, and access covers in both indoor and outdoor installations.

This fastener is suited for use in residential and commercial applications where a tool-free, reclosable attachment is required. It adheres directly to metals including aluminum and stainless steel, glass, and high-surface-energy plastics such as acrylic, polycarbonate, and ABS. Common installation scenarios include securing junction box covers, attaching duct inspection panels, organizing conduit bundles, and mounting light-duty equipment to flat surfaces. Its outdoor rating makes it appropriate for exterior equipment enclosures and rooftop HVAC units exposed to temperature cycling.

Key Features

• Clear polypropylene stems with clear acrylic adhesive backing for low-visibility mounting
• 250 stems per square inch per side for strong, repeatable closure
• Rated for 1,000 open-and-close cycles before degradation
• Temperature resistance up to 220 degrees F for high-heat environments
• Approved for both indoor and outdoor use including UV and moisture exposure
• Bonds to aluminum, stainless steel, glass, acrylic, polycarbonate, and ABS surfaces

Compatibility

Designed for use on metals (aluminum, stainless steel), glass, and high-surface-energy plastics including acrylic, polycarbonate, and ABS. Not recommended for low-surface-energy plastics such as polyethylene or polypropylene substrates without surface preparation.

Installation Notes

Surface must be clean, dry, and free of oils or dust before applying the adhesive backing. Press the fastener firmly against the substrate for full contact and allow adequate dwell time before loading. Power down or de-energize any equipment before routing or securing wiring with this fastener near live circuits. Cut to length with standard scissors or a utility knife.
