## Overview

3M Dual Lock TB3550 is a heavy-duty, reclosable fastener featuring 250 interlocking mushroom stems per square inch, delivering five times the holding power of standard hook-and-loop. Designed for quick, tool-free adhesive installation on diverse surfaces like metal, glass, and plastics, it withstands over 1,000 open-close cycles and extreme temperatures from -29°C to 93°C. Its low-profile black design remains hidden for a clean finish, making it the go-to solution for industrial, commercial, and creative applications requiring durable, repeatable fastening.

## Description

Product Description Unlock simplicity, super strength and ultimate ease. The remarkable 3M Dual Lock Reclosable Fastener can be opened and closed up to 1,000 times before losing 50% of its original strength, for repeated access or repositioning. The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated, the fasteners are hidden from view and leave you with an unbroken surface for a smooth, clean appearance. From the Manufacturer Strength in NumbersOne little mushroom won't accomplish much in this world, but pair him up with a few hundred of his friends and he becomes nearly unstoppable. Teamwork, that's the idea behind the design on the 3M Dual Lock Reclosable Fastener TB3550. When joined together, these unique, mushroom-shaped stems combine to interlock with one another, generating five times the closure strength of typical hook and loop fasteners while maintaining the ability to easily peel-apart for quick access.3M Dual Lock TB3550 Reclosable Fastener contains approximately 250 mushroom-shaped head stems per square inch. When two pieces of Dual Lock are pressed together the stems flex and the mushroom heads slide past each other. After mating, the stem snaps back into its original position, interlocking with the opposing heads with an audible snap that signals the fastener is engaged. This system can be opened and closed 1,000 times while maintaining 50% of the original tensile strength. No Drilling, Screwing, Tightening, or Complex Installation3M Dual Lock TB3550 uses an acrylic adhesive that bonds well to a variety of high medium surface energy materials, including some plastics, metal, glass and painted surfaces. This ensures a quick and easy installation without the use of mechanical attachment processes. The adhesive sticks quickly and reaches full strength after 72 hours. Once bonded the interlocked, mushroom-shaped stems provide an attachment that holds as well as screws or rivets, yet separates easily for access.Versatile, Durable and InvisibleThere's no limit to the number of uses for 3M Dual Lock fasteners. The stems, mushroom tops, and film backing are constructed of clear polypropylene, and the polyolefin backing resist common solvents and alkaline solutions, making them ideal for a variety of purposes and environments. The fastener is recommended for use at temperatures ranging from -20°F/-29°C to 200°F/93”C. Hidden from view when attached, these fasteners provide a clean, unbroken surface, and stay strong through more than 1,000 open-close cycles. Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. They are ideal for both indoor and outdoor applications including: attaching signs, cushions, enclosure and access panels, banners, doors, adjustable shelving, vehicle ceiling panels, furniture seats and backs, and much more.

## Questions & Answers

**Q: What 3M Dual-Lock product and part # has the best adhesive for outdoor auto/motorcycle use**
A: I use this product (TB3550) to mount cameras to my motorcycle. I've not had any issues yet with the adhesive even at speeds of 170mph + (track). I'm not sure you'll find a better product from 3M for these types of applications.

**Q: Would anyone recommend 3M Dual Lock for pedalboards?**
A: Yes, it works great. Be advised, do not use much because it stays together amazingly. It’s a little hard to adhere to the bottom of Boss pedals. I sometimes have to use a little epoxy on the back of the dual lock to help it adhere to the pedal itself. Just a thin strip at the top and bottom is all you’ll need. I recommend getting an automotive trim removal tool from Harbor freight (the yellow ones) to help pry them off when reshuffling pedals. (Yes, even with just a little bit. Then apply some dual lock to the tool and stick it to the bottom of the board. Added bonus: it does not absorb liquids. So spills won’t smell down the road.

**Q: Is this the same as 3M -VHB tape? Dual sided of course but with less adhesive properties?**
A: Not sure of your question but after a year of using this product i have one more comment. It does not work well at all on anything but flat or mating surfaces.

**Q: Just to be clear, it does come with the "fuzz" side as well as the hook side correct? I am only in need of the "fuzz".**
A: No, there is no "fuzz" side on this type. Bothe sides are the same, made out of plastic. When locked, they snap, and it will not let go after that. Prying them apart, they release, but it takes some force. I have used this type on small RC airplanes to full scale flight simulators. This is the top of the line commercial "Velcro".
