The 3M™ Dual Lock™ SJ3551CF is one of the strongest reclosable fasteners in the 3M range — delivering a powerful and reusable bonding solution for industrial, automotive, and display applications.

⚙️ How It Works
Each strip of 3M Dual Lock has interlocking mushroom-shaped stems that snap together to form a strong mechanical bond. Simply apply one side to each surface and press firmly until you hear the “click” — the connection can be opened and closed multiple times.
💡 Tip: For best adhesion, clean both surfaces with isopropyl alcohol before application. Allow 24 hours for the adhesive to reach full bonding strength.
