Scotch Extreme Interlocking Fasteners, 4 Strips, 1" x 3", Delivers Powerful Bond on Contact, Weather, Dirt & UV Resistant, 1 Set Holds 2 lbs., Designed with Reclosable Dual-Lock Technology (RF6731)

This stuff is one of the best inventions 3M has ever made, along with Post-It notes. In the industrial version, it's called Dual Lock, and comes in three different strengths/densities (170, 250, 400); this is the 250 version. There is also a "low profile" version, but this is the normal profile stuff. The three densities are designed to work with each other in various combinations to give you the particular combination or strength/releasability that suits you application best, but 3M does not recommend 170/170 (too weak) or 400/400 (too dense), so you can select 170/250 (lightest strength), 170/400, 250/250 (medium strength), or 250/400 (strongest). If you need to affix something to a surface semi-permanently, this stuff is absolutely amazing, and it is the only thing I will use to build my effects pedalboards for electric guitar and bass guitar. 250/250 holds so strongly that with only a few square inches of bonding, you actually need to get a small prybar to get it to release (unless you use very small pieces of it), and the adhesive holds with incredible tenacity, yet still removes cleanly from painted metal surfaces when you need to remove it. Perhaps even more importantly, the bond between the two sides is solid, unlike hook and loop fasteners, which have a bit of give to them, so that the mated surfaces do not move once joined. For a working musician, these properties make it ideal--it hold pedals onto a pedalboard strongly enough to survive transport, the adhesive removes without residue when you want to sell a pedal, and the pedals don't move or "squish" when you step on them. And it's black with a clear adhesive, so it looks good on stage! I cannot recommend this product highly enough.

I picked these up to mount a few things without drilling, and they ended up being a lot stronger than standard hook-and-loop strips. The first thing you notice is the hold. Once you press them together, they lock in tight and don’t come apart easily. It’s more of a firm snap than soft Velcro, so whatever you’re mounting feels secure. The adhesive backing sticks well as long as you prep the surface. On clean, smooth surfaces, it grabs and holds without peeling up. Once it’s set, it doesn’t shift around or loosen over time. What makes them useful is being able to remove and reattach things without losing that grip. You can pull items off when needed and snap them back in place without the adhesive failing. Build quality feels solid. The plastic interlocking side doesn’t wear out quickly, and it keeps that strong hold even after multiple uses. The only thing to keep in mind is they’re not meant for heavier items beyond the stated limit, and once the adhesive is down, repositioning isn’t really an option. Overall, they do exactly what they’re supposed to do. Strong hold, reusable, and a good alternative to drilling or permanent mounts.

Received In brand new perfect condition. Good product and does the job. Probably order a roll of this next time. Highly recommended!

Used to secure my Fire Stick 4K to my TV stand. Holds very securely and very little heat transfer from the Fire Stick 4K. Perfect size right out of the package.

These are awesome for holding down the edges of an outdoor rug and has kept it from blowing up in the wind! Knocked a star since they don't always stay stuck and definitely have to be repurchased seasonally (sometimes more). Luckily these are very inexpensive and do their job, so I don't mind.

I used these fasteners for many things the nine years we were full-time RVers. They held all sorts of things in place as the RV rolled down the road. Most recently, I used them to fasten a DAKboard CPU (Raspberry Pi) and DC mini UPS to the back of a 32-inch monitor for mounting on the wall in our apartment. This made for a very clean installation and saved me from putting an equipment shelf on the wall behind the monitor. No matter the application, 3M adhesives have always adhered well for me and the interlocking function of these strips is extremely strong. I always keep at least one package on hand for those little projects that pop up. I think they are a bit pricey, but I guess you get what you pay for...

Just needed for basic use. It works for everyday use

Siempre que uso este velcro no me decepciona y cumple su propósito.

Pegúe un pizarron chico a la pared, lo hice con este velcro porque necesitaré quitarlo para limpiarlo en algunas ocaciones y me sorprendió le agarre, que me fué un poco mas dificil despegarlo de lo que pensé... excelente la calidad del material y cumple perfecto lo que menciona

These little fasteners work great! I’ve used them outside and they hold up through rain and heat. Easy to use, clear so they don’t stand out, and really reliable.

Very strong, with a multitude of purposes.

Don't waste your time with the Velcro brand fasteners if you're using for outdoor use. This is the product to go with. No issues with application and has held strong since day one. The Velcro brand product I purchased failed as soon as it rained. This is truly water proof and is as described.
