3M™ Dual Lock™ Reclosable Fasteners
3M™ Dual Lock™ Reclosable Fasteners are a great alternative to traditional fastening methods like screws, nuts, and bolts. Closures are strong, reliable, and yet easily removable without the use of tools. The interlocking mushroom shaped heads allow for easy repositioning prior to closure, allow for invisible fastening, and allow for tool free quick release. Blind fastening is as easy as a snap with the positive audible closure. With multiple adhesive options these products are durable both indoor and outdoor. These products can be cut to the length required for the application.
Applications include: Interior panel attachment on bus, rail, aerospace, ambulances, and elevators. Removable access panels for electrical panels, lighting, and control boxes.
