Why choose it

The high-strength acrylic adhesive bonds to metals, glass, and many plastics, while the Dual Lock stems provide high shear and peel strength. Unlike hook-and-loop fasteners, this tape has no mating halves to align—the same tape engages with itself, simplifying installation. It resists UV light and moisture, maintaining performance in outdoor conditions.

Ideal use cases

• Mounting signs, displays, and panels without drilling
• Securing access panels and trim in vehicles
• Attaching components in industrial equipment
• Temporary or semi-permanent bonding for exhibitions and retail fixtures

Good to know

The tape is supplied on a roll with a clear polyolefin liner. For best adhesion, apply at temperatures between 10°C and 38°C and ensure surfaces are clean and dry.
