About this item

  • FEATURE: Dual Lock Reclosable Fastener SJ3550 is the convenient alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution (which can be opened and closed multiple times) which bonds to a variety of substrates including metals and plastics such as acrylics, polycarbonate and ABS.
  • HIGH QUALITY: Black, interlocking mushroom-shaped heads (250 stem density per square inch) provide strong, reliable and durable fastening that can be opened and closed multiple times. White, acrylic, conformable foam tape bonds well to a variety of substrates including metals and plastics such as acrylics, polycarbonate and ABS. Strong fastener secures with an audible snap, verifying closure. Features good temperature resistance of 200°F (93°C).
  • APPLICATION: This SJ3550 dual lock mushroom clasp uses an acrylic adhesive to bond to a range of high surface energy materials, including some plastics, metals, glass and lacquered surfaces. It enables quick and easy installation without the need for mechanical mounting. After bonding, the interlocked mushroom stems can be fixed, spiral and rivet, but they can be easily separated and accessible to the fixed objects.
  • INSTALLATION AND REMOVAL: At room temperature, approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. Spraying alcohol on the tape then it is easy to peel off. Please clean the bonding surface and do not touch the stick layer before using, if anything touched the stick layer. It will peel away.
  • BOND SMOOTH SURFACE: Bonds most painted metal and plastic without surface residue or abrading. Specially formulated synthetic adhesive bonds most paints and powder coats, as well as window materials such as glass, acrylic, and polycarbonate, stone and wood.

I love this,I have been using it for years, it is super versatile, usable in many different applications. Much better and stronger than conventional Velcro. It sticks well, the plastic teeth hold exceptionally well.I recently used it to install a DVD player and shelves in my new Camper, it holds the shelves for the DVD player and attaching the DVD player to the shelves. I also use it to hold the remotes on a second shelf and the temp gauge.

3M dual lock is a unique product - superior in many ways to velcro. The hold is much stronger and more consistent and the glue is very strong. I ordered the 8 ft piece and it is a great value for how much you get for what you pay. The roll is nice and wide and I ended up cutting pieces in half length wise which made the 8ft go even further.

Used this to replace standard Velcro for mounting a mini light to shotgun and it works great!

Sometimes I need something that can reliably attach and detach. Old-school Velcro wears out after a while and doesn't bind that great. This all plastic Velcro binds really well, but ones that have cheaper adhesive might detach. Also this all plastic Velcro not likely to wear out anytime soon. The adhesive though is wear this item shines. I'd imagine other plastic velcros might actually detach from the adhesive side. Which would be really annoying. Wipe whatever you attach this to with rubbing alcohol makes sure it's free of any dirt, hair, or oils. So far, adhesive has never detached on me. It's pricey, but the reliability is worth it. I've bought this twice. No question will buy again if needed.

Unlike Velcro you will have to buy 8 feet if you want 4 feet. It seems that all dual lock tape is that way. I ordered a couple and all came in the same way. I haven’t tested the grip of the back side yet. I will update when I do.Update: The grip of the adhesive is good. Unfortunately the grip of the removable side isn’t quite as strong. I have standard Velcro that holds better. I wish I could remove another star.

Dual lock is great for a multitude of uses. I use it on my pedalboard and it's amazing. A small little piece goes a long way in securing an effects pedal or whatever you need secured but removable. It's invaluable to me for my pedalboard. Highly recommended.

It's strong enough to keep my light curtains hanged on the wall or the ceiling, I'm surprised how strong they are. It can tears out the paint if you try to remove it. Before installing anything male sure to choose the good and the right place, cause when you remove it, it can probably remove the paint on tje wall. I prefer usong these than making hols on the wall. If you remove them carefully, you can be safe, but overall all good quality, strong glue, easy to use, but a little bit expensive.
