3M 7000001956 Dual Lock Reclosable Fastener SJ3460 Clear

Product Description

The 3M 7000001956 is a clear, plain-backed reclosable fastener sold in a 1-inch-wide by 50-yard roll. This Dual Lock fastener uses a mushroom-stem interlocking mechanism rated at 250 stems per square inch, producing a firm and repeatable closure without adhesive on the mating surface. The engaged thickness measures 0.16 inches. Designed for industrial and trade applications, this fastener is typically installed by maintenance technicians, fabricators, and assembly personnel who need a tool-free reclosable attachment in light-duty panel, fabric, or fixture work.

This fastener is suited for attachment to fabrics using sewing or to wood and similar substrates using staples. Plain-backed construction means there is no pressure-sensitive adhesive on the rear surface, so the installer determines the attachment method. Common applications include equipment panel retention, cable management, fabric attachment in upholstery, and light fixture or access-door closures where repeated opening and reclosing is required.

Key Features

• 250 stems per square inch for a firm, repeatable interlocking closure
• Plain-backed construction allows sewing or staple attachment to fabrics and wood substrates
• Clear material for low-visibility installations
• Engaged thickness of 0.16 inches for predictable stack-up in assemblies
• 1-inch width by 50-yard roll length for flexible field cutting to length

Compatibility

Designed as an OEM-style reclosable fastener for use with mating Dual Lock fastener strips on fabric, wood, and similar substrates requiring tool-free reclosable attachment.

Installation Notes

Installation is performed by fabricators, maintenance technicians, or assembly personnel using standard sewing equipment or a staple gun depending on the substrate. No power shutdown is required for most applications, though installers working near energized equipment should follow applicable NEC guidelines before securing fasteners to electrical enclosures or panels. Cut the roll to length with a sharp blade before applying. Avoid stretching the material during installation to maintain consistent stem density across the closure.
