The fastener features an audible snap when secure, verifying closure of the attachment, and can be easily disengaged by simply peeling the pieces apart by hand. With excellent temperature resistance up to 200°F (93°C) and compatibility with Type 170, Type 250, or Type 400 stem densities for customized strength combinations, this fastener offers remarkable design flexibility.
The reclosable fastener is well-suited for indoor and outdoor applications including access panels, graphic attachment, specialty vehicle interior attachments, general industrial attachment, and small component fastening. Installation requires no drilling, screwing, or sewing tools, enabling quick and efficient assembly.
