The 3M™ Dual Lock™ Reclosable Fastener TB3870

The 3M™ Dual Lock™ Reclosable Fastener TB3870 is a remarkable product that can be opened and closed up to 1,000 times before losing 50% of its original strength. The mushroom heads easily slide over each other, allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the black fasteners are hidden from view, leaving you with an unbroken surface to help create a smooth, clean appearance. The type 250 stem density polyolefin fastener mates to Type 170, 250, or 400, giving the user the option of different closure strength depending upon application.

Applications:
  • Indoor/outdoor
  • Doors
  • Flexible solar panels
  • Headliners
  • Access panels
  • Signs
  • Display components

The fastener is backed with a modified acrylic pressure-sensitive adhesive that bonds to many plastics and powder-coated paints, as well as medium to low surface energy materials with little or no surface preparation.

Hear the Snap

"Snap!" It's the one word that best defines the extensive line of 3M™ Dual Lock™ products. When two pieces of 3M Dual Lock Reclosable Fastener are pressed together, the stems flex, and the mushroom heads slide past each other. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. Listen for the audible snap to signal that the fastener is engaged. The attachment formed may be as effective as screws or rivets but will peel apart for repositioning. 3M Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets.

Lose the Screws

The bond is strong but can easily be detached; just pull apart to disengage and reattach as needed. This means that this product gives you a strong, hidden bond with the convenience of multiple openings and closings so you can lose the screws, rivets, hooks, bolts, zippers, and other unsightly attachment methods. In short – this product is an aesthetically pleasing fastener that doesn't sacrifice attachment strength. In fact, the 3M™ Dual Lock™ Reclosable Fastener TB3870 is about five times stronger in tensile strength than 3M™ Hook and Loop fasteners used in comparable applications. In many cases, this attachment method also saves the user money with less material used. Additionally, there's no need to drill holes that might weaken the part or substrate, and no tools required to assemble and remove the part.

You can expect more options to secure, attach, and connect surfaces with 3M Dual Lock Reclosable Fasteners. They offer quick installation and high-strength attachment, yet can be opened as easily as zippers. That functional flexibility, as well as superior aesthetics, reduced weight, and savings in labor and installation costs, make innovative 3M fasteners a popular and effective solution.
