Secure Your Gear with USA's Strongest Reclosable Fastener

About this item

3M Dual Lock SJ3550 250 fastener provides a robust, reclosable closure solution, replacing screws, snaps, and bolts. This 1-inch wide by 4-foot long roll features Type 250 (approximately 250 stems per square inch) for a secure, high-strength attachment. The advanced adhesive backing bonds firmly to metal, plastic, and most rigid or flexible surfaces, offering design flexibility and faster assembly. It is resistant to solvents, moisture, and plasticizers, and withstands heat up to 200°F (93°C), making it suitable for demanding applications.

The interlocking mushroom-shaped stems easily slide over each other for precise positioning before snapping together. This creates a strong, reliable fastening attachment that can be opened and closed instantly by simply pulling the strips apart. Its durability and clean exterior surfaces outperform traditional Velcro, making it a superior choice for applications like pedalboards, mounting, and general repairs where a dependable, long-lasting hold is required.

Imported from authorized US retailers and authorized brand partners, this 3M Dual Lock fastener offers authentic quality for your projects. All customs duties and GST are included in the displayed price, ensuring a transparent purchase. Delivery is via ExpressBox tracked shipping, arriving within 14-16 days.

Key Features

  • 3M Dual Lock Black Reclosable Fastener offers advanced closure alternatives to screws, snaps, hooks, bolts and more! Great for pedalboards!
  • Instantly open and close by pulling the interlocking strips apart.
  • Adhesive backing adheres to metal, plastic, and most rigid or flexible surfaces.
  • Resistant to solvents, moisture and plasticizers. Resists heat up to 200 degrees.
  • Roll size 1" wide x 4 feet long.

Why choose this product

Engineered for Superior Performance

3M Dual Lock fasteners utilize interlocking mushroom-shaped stems that create a high-strength, audible snap closure. This design offers superior holding power and durability compared to traditional hook-and-loop fasteners. The advanced adhesive ensures a reliable bond on a wide range of surfaces, from metal and plastic to flexible materials, making it ideal for demanding applications where strength and reusability are paramount. Its resistance to heat, moisture, and solvents further enhances its performance in challenging environments.

Ideal for Organizers and Builders

This fastener is perfect for musicians creating custom pedalboards, DIY enthusiasts mounting items, or anyone needing a robust, temporary or permanent attachment solution. It's particularly suited for those who value a clean, screw-free finish and the ability to easily reposition or remove components. While excellent for general mounting and organization, individuals requiring extreme weight-bearing capacity beyond 5 lbs per square inch might consider specialized industrial mounting solutions.

How to use

  • Prepare Surfaces — Ensure the surfaces where you will apply the fastener are clean, dry, and free from dust or grease. For best adhesion, use an isopropyl alcohol wipe on both surfaces.
  • Cut to Size — Cut the 3M Dual Lock fastener roll to the desired length using scissors or a utility knife. You will need two pieces of equal length for each attachment point.
  • Apply Adhesive — Peel off the protective backing from one piece of fastener and press it firmly onto one surface. Repeat with the second piece on the other surface, ensuring alignment.
  • Engage and Secure — Align the two pieces of fastener and press them together until you hear or feel an audible snap. This indicates a secure engagement. To disengage, simply pull the strips apart.
