3M 7010300425 Dual Lock Fastener SJ3968 Black 1.5in X 50yd

Product Description

The 3M 7010300425 is a Dual Lock Reclosable Fastener sold as roll SJ3968 in black with a 250 stem density. This interlocking fastener system uses mushroom-shaped stems that engage with opposing stems to create a secure, reclosable bond without hooks or loops. It is designed for repeated attachment and detachment cycles in applications where a strong, tool-free mechanical fastener is required. The roll measures 1.5 inches wide and 50 yards long, giving installers ample material for high-volume jobs. Electricians, HVAC technicians, and general tradespeople use this product to secure panels, wire bundles, trim pieces, and lightweight equipment to surfaces.

This fastener is suited for both residential and light commercial applications where a clean, low-profile mechanical attachment is needed. Common uses include securing access panels, cable management, control box covers, and other components that require routine removal for service or inspection. The black color allows it to blend into dark enclosures or equipment housings. The roll format makes it practical for job-site cutting to custom lengths.

Key Features

• 250 stem density for consistent, repeatable closure strength across the fastening surface
• Reclosable design allows repeated attachment and detachment without adhesive residue transfer between mating surfaces
• 1.5 inches wide roll format cuts easily to any required length
• 50-yard roll length supports high-volume or multi-unit installations from a single roll
• Black color integrates with dark panels, enclosures, and equipment housings

Compatibility

Designed as a reclosable mechanical fastener for use with mating 3M Dual Lock surfaces or other 250 stem density Dual Lock strips in standard trade and industrial assembly applications.

Installation Notes

Surface preparation is critical before applying the self-adhesive backing — clean the substrate thoroughly and allow it to dry completely before installation. Cut the roll to length using scissors or a utility knife on a stable work surface. When bonding two Dual Lock surfaces, align them carefully before pressing together, as engagement is immediate and repositioning requires firm separation force. Follow any applicable building or equipment manufacturer guidelines for mechanical fastener use in electrical or HVAC enclosures.
