3M Dual Lock Reclosable Fastener SJ3741 is a black, polypropylene reclosable fastener roll good without pressure sensitive adhesive. This fastener is available in a number widths and has a stem density of 400 stems per square inch.


3M™ Dual Lock™ Reclosable Fastener SJ3741 is a black roll good without pressure sensitive adhesive and with a stem density of 400. 

How It Works
This reclosable fastener features mushroom-shaped polyolefin stems that snap together. 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 opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. These fasteners can provide high tensile strength but can be opened by simply cleaving or peeling open the closure.

Recommended Applications
3M™ Dual Lock™ Reclosable Fasteners can replace conventional mechanical fasteners in a wide range of assembly and attachment applications where reclosability or serviceability is desired. Dual Lock fasteners are used primarily to secure rigid and semi-rigid surfaces such as trim or door panels, instrument panel bezels, headliners and other automotive interior and exterior trim. Some examples of applications include:

  • Vehicle headliners
  • Attaching accessories and equipment
  • Attaching window and door trim panels
  • Vibration and sound damping control
  • CHMSL cover plates
  • Center console flanges
  • Interior trim
  • Sunroof rings
