3M 7100023047 Dual Lock Reclosable Fastener 250/250 Black

Product Description

The 3M 7100023047 is a dual lock reclosable fastener strip rated at 250 stems per square inch on each mating surface, delivering a firm mechanical closure without hooks or loops. The black polypropylene strip is backed with a modified acrylic pressure-sensitive adhesive for direct bonding to a wide range of surfaces. The engaged thickness measures 0.24 inches, keeping the profile low after fastening. Closure life is rated at 1,000 open-and-close cycles. Temperature resistance reaches 180 degrees F, making it suitable for moderate-heat environments. This product ships as a 1-inch-wide by 10-foot roll.

This fastener is intended for both indoor and outdoor applications where a repositionable or reclosable mechanical bond is needed. It bonds well to many plastics including polyethylene, acrylic, polycarbonate, and ABS, as well as powder-coated painted surfaces and medium to low surface energy materials. Typical uses include panel attachment, equipment access covers, cable management, and component mounting in HVAC, electrical, and general trade applications where screws or permanent adhesives are not practical.

Key Features

• 250 stems per square inch on each mating surface for reliable mechanical engagement
• Modified acrylic adhesive backing bonds to plastics, powder-coated paints, and low surface energy materials
• Rated for 1,000 closure cycles, supporting repeated access applications
• Temperature resistance to 180 degrees F for medium-temperature indoor and outdoor environments
• Low-profile 0.24-inch engaged thickness minimizes added bulk
• Black polypropylene construction resists moisture and UV exposure in outdoor installs

Compatibility

Compatible with polyethylene, acrylic, polycarbonate, and ABS plastics, as well as powder-coated painted surfaces and medium to low surface energy materials. Designed for use in both indoor and outdoor environments.

Installation Notes

Surface preparation is critical before applying pressure-sensitive adhesive fasteners — clean and dry the mounting surface thoroughly, removing oils, dust, and loose coatings. Apply firm, even pressure across the full length of the strip to ensure full adhesive contact. Allow adequate dwell time before applying load as recommended for acrylic adhesive systems. No tools are required for application, but surface temperature at time of install should be within the product operating range for best adhesion.
