Practical & Flexible: 3M Dual Lock™ Reclosable Fastener in Dispenser Box

The 3M Dual Lock™ is a reclosable fastener in the form of a roll of tape and consists of black and transparent polyolefin strips with undulating mushroom-shaped heads. These slide over each other during assembly until they are anchored together by pressure. Users can hear when the pressure lock tape is fastened together. This prevents faulty closures or premature connections. It can be crossed, offset, or overlapped, loaded for tensile as well as shear strength, and is vibration-resistant. This means that it provides a permanent mechanical fastening that does not unfasten even when it is subjected to sustained vibrations.

Unlike conventional fastening systems, its self-adhesive nature eliminates the need for inconvenient screwing or riveting, prevents visible holes, and maintains the visual appearance of the surface.

3M Dual Lock™ reclosable fastener applications

The flexible pressure lock tape is a practical and invisible fastening solution, e.g., for cladding or covers, that can be quickly and easily unfastened and refastened during assembly, maintenance, or repair. With 3M Dual Lock™, the fastening can be released up to 1,000 times. The interlocking tape is used in a variety of fields such as the automotive, appliance manufacturing, toy, and furniture industries as well as machinery and equipment engineering.

Suggested applications include:

• Attaching graphics
• Fastening at specific points
• Hanging signs
• Various indoor applications, e.g., in offices
