3M 7000049437 Dual Lock Reclosable Fastener 2in X 45yd Black

Product Description

The 3M 7000049437 is a black polypropylene Dual Lock reclosable fastener tape engineered for secure, tool-free mechanical attachment in both indoor and outdoor environments. It features a modified acrylic adhesive backing that bonds to a wide range of substrates and delivers 250 stems per square inch for consistent, repeatable closure. Engaged thickness measures 0.24 inches. The tape is rated to withstand temperatures up to 180 degrees F, making it suitable for medium-temperature applications. Each roll measures 2 inches wide by 45 yards long and weighs 7.72 pounds. Licensed HVAC technicians, electricians, and industrial installers rely on this fastener for panel mounting, wire management, and component attachment.

This fastener tape is used in residential and commercial applications where screws, bolts, or adhesive-only solutions are impractical. It adheres to many common plastics including polyethylene, acrylic, polycarbonate, and ABS, as well as powder coated paints and medium to low surface energy materials. Typical install scenarios include securing access panels, attaching control modules, organizing cable runs, and mounting lightweight components to enclosures or equipment housings. Its outdoor rating makes it a practical choice for equipment installed in exposed or semi-exposed locations.

Key Features

• 250 stems per square inch for strong, repeatable mechanical closure
• Modified acrylic adhesive backing bonds to plastics, powder coated paints, and low to medium surface energy materials
• Temperature resistance up to 180 degrees F for medium-temperature environments
• 0.24-inch engaged thickness provides consistent mating depth
• Rated for both indoor and outdoor use
• Closure life rated at 1,000 open and close cycles

Compatibility

Compatible with many plastics including polyethylene, acrylic, polycarbonate, and ABS, as well as powder coated paints and medium to low surface energy materials. Designed for use as a reclosable mechanical fastener wherever a mating Dual Lock surface is present.

Installation Notes

Surface preparation is critical — clean and dry the substrate thoroughly before applying the adhesive backing. Apply firm, even pressure across the full tape length to ensure full adhesive contact. Allow adequate dwell time before loading the joint with force. For electrical enclosures or HVAC equipment, power down the unit before attaching or removing any fastened panels or components.
