3M Electronic SJ3550 1/2 in X 50 Yd Black Fastener Tape

Product Description

The 3M ELECTRONIC SJ3550 1/2 IN X 50 YD BLACK is a reclosable dual-lock fastener tape designed for secure, repeated attach-and-release applications. This tape uses interlocking mushroom-shaped stems that engage with an audible click and hold firmly until manually separated. It is sold as a single roll and is commonly used in electrical, HVAC, and general trade applications where a reusable mechanical fastener is needed without tools or adhesives for the closure mechanism. The black colorway suits installations where a low-visibility finish is preferred.

This fastener tape is suited for residential and light commercial installations where components need to be mounted, secured, or repositioned repeatedly. Typical uses include securing wire harnesses, mounting control panels, attaching access covers, and organizing cables in HVAC equipment, electrical enclosures, and panel assemblies. Technicians in HVAC, electrical, and general trade work use this product where screws or permanent adhesives are impractical.
