Have a Question? See What Others Asked

Because it's mated, is the actual usable length 1/2 of the length listed?
is the length described refering to the actual mounting length? or in reality one gets half because you need to use two pieces of the tape?
Does the adhesive get soft when it warms? I want to use in a window to hang foil/foam insulation. Hook/loop adhesives tend to let go when sun hits it.
is thisw waterproof?

Good tape.

Got this for a special reason it turns out it works great for putting velcro on patches and putting the patches on what you want instead of sewing or glueing. And you can switch the patches around if they are in similar sizes

Painted brick

Best solution I've found for hanging framed pictures on a painted brick wall. I've bought these multiple times from different vendors. Great product.

Excellent and Useful Product

This is not the first time I am buying this product. It is very useful and well made. It has a very strong hold. It isn't a hook and loop (velcro) which wears out every time one peels them apart. This is called a dual lock, and there are no loops to wear out. I've been shopping at TEMU almost everyday for months now and this is one of the very few items Amazon sells for less than TEMU. I was actually surprised.

5 Stars – Super strong and super useful

This 3M Dual Lock is awesome. Way stronger than regular Velcro and clicks together with a solid snap. The adhesive sticks really well, even outdoors. I've used it to mount tools and gadgets—no issues at all. For the price, it’s a great deal. Definitely buying more!

Extra Strong Gripping Strength!

This tape puts regular hook and loop (Velcro) tape to shame. I tried the regular stuff to attach my garage door opener to the back of the display in my Tesla. When it got hot out the tape melted off. This stuff has no problem holding up (pun intended) to the heat. Love It!!
