3MDual Lock Reclosable Fastener TB4575, Black, 1 in x 10 ft

Easy to use, seems to stick well -- time will tell, of course. I like that it's more flexible than traditional hook-and-loop, since you can re-use it in other places witbout trying to remember if you used hook or loop part previously (RC batteries, for example).

First experience with Dual Lock has been wonderful.Some quick technical information that may be helpful:- Maximum upper operating temperature 70C (158F)- Rated for use on surfaces with medium to low surface energy (Not high!)- Type of adhesive used is acrylic based- Thickness when two pieces joined together is 0.098 inches (pretty darn thin)I used this in a client's prop project to fasten components that would need to be removed for servicing. These components were interaction features (button and switch panels) as well as operating infrastructure components (sub-assemblies inside of enclosures).The constraints I needed to work around in the project were the following:- No lateral give during the interaction (the component must remain firmly in place and not "mush" around)- Hold up to temperatures that would be experienced while stored in a van outdoors (prop sometimes stored outdoors when on tour)- Must be able to affix to powder coated metalI can attest to the following:- Very solid feel once joined. The locking action of all the little plastic mushroom spikes really keeps an object in place no matter what direction it's being pushed from. It feels almost like a mechanical fastener.- It is holding up very good stored in a non air conditioned southern-weather room. Automotive has not been tested yet, but it will probably be okay. The rated temperatures are borderline to what I would WANT for automotive ratings, but I think since it won't be undergoing physical interaction during the hottest of times it will survive just fine. I can say that the roll has been living in my car between projects just fine, though.- It stuck to the powder coated metal way better than I was anticipating. The powder coating resembled a low-profile "hammertone" finish (not a super aggressive one). I surfaced prepped the area with rubbing alcohol before adhering. I can also say it stuck to wood that had been sanded smooth, then painted, then sanded smooth again. The painted/sanded wood was cleaned with rubbing alcohol before adhering. All points of adhesion were given a "cure time" before they were subjected to separation forces. While I nearly required a screwdriver to pry the joined surfaces apart, the adhesion did not give before the locking spikes.Client was worried about using "Velcro" like material, but has since declared Dual Lock the technology of the future.I will likely be using more of this or similar product in future projects.

It just works. The adhesive is great and doesn't leave any residue. The "velcro" part is superb. Parts just snap in and out of place. Great job, 3M. I'm glad I no longer have to use actual velcro like a barbarian. Expensive but worth the price for the jobs I use it for.

This stuff is cool. I use it on my mini pedalboard, which weighs around 15-20 lbs. With this stuff, I can grab a nano pedal and pick the entire board up by a single pedal, then shake and jiggle it around, and never worry about anything coming out of place.I do have issues with pedals coming off if I step on a cable near the board. If you roll the pedals to the side rather than pulling them upward, the dual lock comes apart much more easily. It is not so impossible to get off in this way as some say, but it does hold very well and it also isn't too bad about retaining pet hair/dust when sitting around. I consider it a great improvement over Velcro.I used a hair dryer to heat the dual lock and the metal surfaces I was sticking it to, then used a round lint roller to roll it firmly into place while hot, then let the glue set for 8-12 hours (24 is recommended) before putting the pedals on the board. I did have issues with adhesive failing on foam pads on pedals or when using standard Velcro on metal bits, but I have had no issues at all with the adhesive on the dual lock so far. This is partially because of the technique I used to apply it and partly because it has great adhesive.I highly recommend this over Velcro unless you need to secure something that needs to be removed repeatedly. If you plan to constantly be re-securing things or rearranging, industrial grade Velcro might be a better option. For anything semipermanent, dual lock is king.

I've been using Dual Lock strips for years. I've used it for everything from mounting battery supplies on equipment to attaching accessories such as external hard drives to the back of my laptop just to de-clutter my workspaces. Though, I must stress the importance of using narrow strips of this if you use it for this purpose. Otherwise, the Dual Locks will hold too tightly, causing you to put too much pressure on your laptop display and potentially breaking it. Fortunately, I already knew how strong these are. So, I took that into consideration before adhering any strips to the back of my screen.The biggest test I've given these strips is when I attached my camera tripod to my backpack to cheat the system regarding carry-on bags. I put (2) 1" x 5" Dual Lock strips on my backpack, placing them parallel from each other, far enough to match with 2 legs of my tripod. Then I placed a 1" x 18" Dual Lock strip on each leg of the tripod. Not only did the tripod hold fast to my backpack, this also allowed me to attach other things to my tripod – backup batteries, field recorder, accessory cases or bags, etc.I personally think they are overpriced. However, I still buy them.

Worst Velcro I've ever used. Doesn't grab. Falls off.

Title states that it is indoor/outdoor. It is not and the package states indoor use
