## Description

Hool and loop strips

Review: So strong - It's strong enough to keep my light curtains hanged on the wall or the ceiling, I'm surprised how strong they are. It can tears out the paint if you try to remove it. Before installing anything male sure to choose the good and the right place, cause when you remove it, it can probably remove the paint on tje wall. I prefer usong these than making hols on the wall. If you remove them carefully, you can be safe, but overall all good quality, strong glue, easy to use, but a little bit expensive.
Review: You won't be disappointed... - This is not the velcro you're typically familiar with. It works like velcro in concept but much better. A little bit of this goes a long way as it is very strong. The adhesive that's on the back side is extremely aggressive...in other words once you stick it, it's not coming off easily. I've used this to mount electronic equipment under shelves and to mount valances over window blinds and a few other things. It's solid. Works just like velcro but its not made of same material velcro is made of.

## Questions & Answers

**Q: Because it's mated, is the actual usable length 1/2 of the length listed?**
A: Yes.  This product is all I use on my pedalboards.

**Q: 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?**
A: It is the actual length of the roll. There are different types of Dual Lock, allowing a person to mix and match types allowing for different amounts of adhesion between two devices.

As an example, you may want less adhesion for a removable TV remote control mounted to a wall, vs mounting a IP-TV permanently to a surface behind the display. This is doble by mixing and matching Dual Lock products.

**Q: 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.**
A: It will if exposed to direct sunlight.

**Q: is thisw waterproof?**
A: Hard to say without knowing the intended application. The construction of the hook and loop is entirely plastic so yes there. The adhesive is very strong however I doubt it would withstand constant submersion. If were talking a bit of rain here or there. I'd bet it would last through a season, depending on the application surface. Make sure its clean and dry and kept dry for a few days until it is "set". Hope that helps
