    Yes, you can! This product works well on different surfaces including metals, plastics and woods.

  3. How much of the SJ3550CF Reclosable Fastener comes in each roll and how many rolls come in a case?

    . Each black roll contains approximately over 50 yards of tape. There are two rolls per case.

  4. Is the adhesive backing strong enough to hold large objects or only for lightweight applications?

    . The SJ3550CF Type 250 reclosable fastener has mushroom-shaped stems which interlock and provide up to five times more holding power than traditional hook-and-loop closures but we would recommend consulting with your application engineer regarding your specific project requirements concerning sizes and weights.

Unlock Simplicity

Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3550CF has exceptional strength through its interlocking mushroom-shaped heads (250 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. This fastener was designed with a clear, acrylic, tape protected by a removable, film liner. This solid, pressure sensitive tape features a strong, durable bond that is heat, chemical and UV resistant. With 3M™ Dual Lock™ Reclosable Fastener SJ3550CF, there is no need for any drilling, screwing or sewing tools which makes for quick installation.

Recommended Applications:
  • Access panels
  • Graphic attachment
  • Specialty vehicles (interior attachments)
  • General industrial attachment
Design Flexibility

3M™ Dual Lock™ Reclosable Fastener SJ3550CF 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. This reclosable fastener 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.

Hundreds of Reattachments in a Snap

When two pieces of 3M™ Dual Lock™ Reclosable Fasteners mate, the stems flex and the mushroom heads slide past each other. After passing the opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. These fasteners can provide high tensile strength but can be opened by simply cleaving or peeling open the closure. This product is well suited for many indoor and outdoor applications where a high strength and versatile reclosable fastening system is required.

Delivers Long-Lasting Performance

Not all design requirements are easily satisfied, but you can simplify your attachments. When you need a strong, reliable, yet removable closure, 3M™ Dual Lock™ Reclosable Fasteners are the easy alternative to traditional fastening methods such as screws, nuts or bolts.
