3M™ Dual Lock™ Reclosable Fasteners
When you need a strong, reliable attachment that also opens and recloses, look no further than 3M™ Dual Lock™ Reclosable Fasteners. Strong, interlocking mushroom-shaped heads slide past each other to close with a snap, then peel apart easily when you need to reopen. 3M™ Dual Lock™ Reclosable Fastener strips make excellent quick-release access panel fasteners and die-cut pieces can also be used to attach accessories to a dashboard or windshield. The quick-release fastening can also be used for interior panels that require maintenance or changeable signage and display units.
