3M 7000049615 Dual Lock Reclosable Fastener 3/4in X 45yd

Product Description

The 3M 7000049615 is a reclosable fastener featuring a modified acrylic adhesive backing on a black polypropylene base. It delivers 170 stems per square inch and an engaged thickness of 0.24 inches, providing a firm, repeatable mechanical closure rated for up to 1,000 open-and-close cycles. The adhesive bonds to a wide range of surfaces including polyethylene, acrylic, polycarbonate, and ABS plastics, as well as powder-coated paints and medium to low surface energy materials. HVAC, electrical, and general trade installers use this fastener wherever a tool-free, serviceable closure is needed on panels, wire bundles, or access covers.

This fastener is suited for both indoor and outdoor applications where medium-temperature performance is required. It carries a temperature resistance rating of 180 degrees F, making it appropriate for use near warm mechanical components or in enclosed equipment spaces. The roll format at 3/4 inches wide by 45 yards long provides a practical working length for production runs or repetitive field installations. Typical scenarios include securing access panels, mounting cable trays, and fastening lightweight components where repeated removal is part of normal service workflow.

Installation Notes

Surface preparation is critical before applying the adhesive-backed fastener; clean the mating surface of dust, oil, and moisture to ensure full adhesive contact. Apply firm, even pressure across the full length of the strip to seat the adhesive. Allow adequate dwell time before placing the closure under load. Electrical and HVAC technicians should power down or de-energize equipment before working in enclosed panels or junction areas where this fastener is being applied.
