3M Dual Lock Reclosable Fastener SJ3444 has a non-woven material on the back of a black, polypropylene reclosable fastener. 3M Dual Lock Reclosable Fastener SJ3444 has 170 stems per square inch with an engaged thickness of 0.28 inches. The closure life is 1,000 times. 

3M Dual Lock Reclosable Fastener SJ3444 consists of interlocking mushroom-shaped heads that easily slide over each other, allowing for positioning of parts before being snapped together. This fastening process creates a durable attachment and provides fast product assembly with great design flexibility. Reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.

3M Dual Lock Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the pieces apart by hand. These fasteners maintain their strength throughout multiple attachments and detachments. A lightweight alternative to metal fasteners, this product remains hidden beneath surfaces and does not interfere with the integrity of your material—providing aesthetic improvements and design flexibility.
