Product 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 Numbers
One 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 Installation
3M 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 Invisible
There'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.

I use the Dual Lock to fasten devices onto my motorcycle tank. So far, I’ve had no failures. The adhesive is very strong and reliable. Obviously, the greater the surface area coverage, the stronger the grip. Great product.
Beware however, because this listing is for 10 ft of mated Dual Lock, meaning you should receive 20 ft of unmated Dual Lock (two 10 ft unmated rolls). Some sellers send only a single 10 ft roll of unmated Dual Lock. Make sure you receive the right amount, and return the item if necessary, so you don't get ripped off.
No more hooks and loops anymore, this product mates with itself and doesn't have the destructive "tear" when separating. The pieces interlock and grip like nobody's business. Package says good for 1000 separations (that's a lot) and I believe it.
A couple of tips:
1. Although the backing adhesive is excellent, make sure you clean the mounting surfaces well with alcohol to remove any trace of grease. Remember this stuff is strong, so you need a good adhesive bond that will withstand the force of separation.
2. Try not to upset the roll when it arrives. Don't unravel it. I pull it out from the center. The reason is if the film that protects the mounting adhesive gets separated you may be compromising the sticking properties. That would make it wear out faster.
3. Plan carefully exactly how much you need. This stuff is expensive but works so well you may need less than you think! You can also cut it lengthwise for thinner strips. This has worked well for me.
4. Note: the adhesive is white which will stand out if placing on glass like a windshield.
5 stars. Another fabulous 3M invention!
If you're willing to spend the money, 3M has some fantastic fasteners and adhesives, and this one is no exception. I've also used it in my amateur radio "go box" to mount the antenna tuner to the rack shelf and I don't have to worry about it coming undone.
The roll comes with both sides of the fastener, and both have double stick tape. Simply cut it to length, pull off the tape backing, and put it where you need it. The tape will take care of the rest.
I put two strips on the underside of the pedal - at the top and the bottom - to prevent it from rocking, and the pedal stays perfectly secure. You don't need more than that (i.e., don't completely cover the underside of the pedal) else you risk never getting the pedal off the board! This stuff is strong and latches securely, and so far the glue has held up well too. And, the higher profile tape is stronger than the low-profile, so you can get away with even less if using the high profile. My advise is to use this stuff when you have a definitive pedal board arrangement and don't plan on changing around that much. Because once you set the pedal in place, the strong grip wants to stay gripped.

UPDATE: This tape did not stick well to my Donner pedals that had a rubber-covered metal bottom plate. However, the rubber can be peeled off the bottom plate to expose the metal.
