Self-adhesive Dual Lock Fastener 3M 7100017793, 25 mm width x 1.25 m length

3M Dual Lock Fastener 7100017793 is a self-adhesive reclosable fastening tape 25 mm wide and 1.25 m long designed for removable panel, trim and sign attachments. The fastener uses interlocking mushroom-shaped stems to form a durable, reclosable connection that replaces mechanical fasteners in many light-duty indoor applications. The pressure-sensitive adhesive backing allows tool-free installation on clean, dry surfaces, enabling quick assembly and later removal without visible hardware.

Advantages

The product provides a strong, reusable interlocking closure that resists shear and vibration while enabling repeated opening and closing. Its self-adhesive backing simplifies installation and eliminates drilling or protruding fasteners, giving a clean appearance. The low-profile tape is suitable for narrow joints and trim work and supports quick alignment during assembly. As a removable fastening solution, it reduces installation time and can help avoid damage to panels and substrates when access is required.

Suitable for

• Mounting lightweight panels and trim where periodic removal is needed
• Fixing signs, nameplates and displays in retail or office environments
• Temporary assembly and fixtures for events or prototypes
• Hiding small cable runs and securing interior trim pieces

How to use

Ensure bonding surfaces are clean, dry and free of dust, grease or residues; use isopropyl alcohol if necessary and allow the surface to dry. Cut the required length of tape, peel the liner and apply the adhesive side firmly to the first surface using even pressure. Align and press the mating piece onto the tape to engage the interlocking stems. Allow adhesive to develop bond strength per normal pressure-sensitive adhesive behavior before subjecting to load; avoid heavy loads or continuous outdoor exposure unless tested for the specific application.

Usage recommendations

For best results, apply at room temperature and press firmly along the full length to ensure maximum contact. Test a small area if using on painted or delicate finishes and avoid use on rough, dirty or low-energy plastics without prior adhesion testing.
