ScotchExtreme 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)

velcro on steroids. amazing stuff. just like regular velcro except this stuff is almost permanent. for example, i work on experimental airplanes and i dont velcro the wings on but i use this stuff to attach fairings on wheels and struts. so these airplanes can go about 200 mph (rv8 for example) but none of these things has ever failed. AND you can take the fairings off, like checking for brakes, bearings, bolts, and landing gear, without tools. if i had just thought this stuff up i could be a rich man. now all i can afford is a six pack of cheap beer for saturday afternoon.

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.

Good stuff. Plenty strong. Adhesive backing holds up well.

Great replacement for EZ pass sticky.

I bought these because I wanted to attach a hook part of "hook and loop"/Velcro strips to a caddy that I wanted to secure to the carpet in my vehicle. While this worked ok for that purpose, it's more like "hook and hook" fastener. Don't expect this to work with other Velcro things you might have. It works well with its own parts, however, and the adhesive back has held up well in the crazy summer heat in my vehicle.

Works fine, best for affixing things to remain in place, until desired to move them.

Our toddler always tries to get down from the table without finishing his vegetables, but since we started using these to fasten him to his chair, he only moves when WE say he's done. Thanks, 3M!
