I used some of this to hang a heavier photo on my wall. Works great but the fastener connection is so strong that they stayed connected and pulled the paint off my wall instead of separating.

Make sure you need industrial strength reclosing and adhesive before using!

This product is one of the best re-closable fasteners I have ever used. I use it for my Ham radio equipment in my vehicle and it works great (keeping the weight in mind). It is supper for most projects that require removing and putting the item back for use in the same location.
I would remind users that it will stick to most surfaces if properly prepped following the directions. However, it will not stick to all surfaces and users must understand that. It is a great product and I would recommend it highly.

I bought a magnetic spice board and a magnetic knife bar for a friend for Christmas. The only issue was that we didn't want to make permanent holes in her solid slab granite backsplash. Dual Lock provided the perfect alternative. It was easy to trim and stick where it was needed. I'm not sure what the maximum weight for the fastener is - but I'd love to know!

Good price, well, a little pricey, but well worth it. Had tried power grip, but came back to 3m dual lock. Power grip was $15 for 1 meter, and the grip was good, but it was not durable. Tore nubs out every time I separated it. Got the 250 nub density/low surface energy adhesive/regular thickness and it works great. I made a pedal board out of wood and finished it. The adhesive sticks strong, no problems. There is a low profile version, but I got the regular thickness since some of my pedals have screw heads sticking out on the bottom. Pulled apart several times to reposition pedals and so far absolutely zero nubs have pulled out. This stuff just works great!

This stuff is great....had tough automotive accessory attachment job that even the best 3M AUTO tape couldn't handle and that I was about to give up on....this easily accomplished the task.....highly recommend.........be careful to place it where you want it to hold,because it will not easily peel off the sticky side surface you place it on....interlocking was as simple as pressing surfaces together.....glad I read other reviews on Amazon that prompted me to try it

This stuff works great and has an extremely strong hold. I use it primarily on a pedalboard with some requirement to heavy to secure with Velcro especially when traveling. The one thing I would have done different on my board is use significantly less of this, on the rare occasion I need to remove or move something on my board it takes a massive amount of effort. There is a similar product marketed as for pedalboards but this is the same thing and much cheaper.

This stuff is awesome, I used for a window insulation project I invented. Its perfect for hanging heavy stuff on the walls like heavy picture frames or a note board or equipment such as light fixtures or smoke alarms and anything you want to put on your walls that's not to heavy and perfect for if you don't want to break out the tools and start screwing holes in the walls.

I used this to mount a small ham radio to my motorcycle. I was a little nervous that it wouldn't be strong enough to hold but it has done great. I actually have to get some leverage on it to remove the radio. I appreciate that the foam backing is black as opposed to most others that are white.
