Product Description

3M Scotch SJ4575 Dual Lock Low Profile Reclosable Fasteners can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. Amazingly thin and reclosable, yet strong, 3M Dual Lock Low Profile fasteners are thinner and more flexible than other reclosable fasteners. SJ4575 is backed with 3M 300 LSE Laminating adhesive, giving it an excellent bond to many substrates including polypropylene, polyethylene, metal, finished wood and many others. Used in POP (point of purchase), trade show exhibition and electronics, Dual Lock low profile reclosable fasteners attach ceiling tiles, carpet, seat cushions, trade show graphics, access panels, wall panels and small electronic devices. They are also great for attaching E-ZPass tags to car windshields. 3M typically recommends 4 square inches of fastener per pound of static load for their low profile dual lock products.

Dual lock only has one type of side; unlike Velcro where there is a separate hook and a loop side; so rolls are typically cut in half and then mated or connected so a 10 foot roll would be used as two 5-foot strips. Low profile dual lock has about 700 stems per square inch, but the stems are much shorter than standard dual lock which has either 170, 250 or 400 stems per square inch. They let you make a much thinner joint (an object being mounted would not stick out as far), but it doesn't have the holding power of standard dual lock. However for smaller, lightweight items it is ideal.

3M Apparently makes 2 different Dual Lock products.

This one is the "Low Profile" and it has less than 1/2 the hold of the regular version that has the white backing rather than this brown paper backing.

The adhesive on this compared to the regular version is about 1/10th the strength. I would never get this unless I had a very specific need for it to have a slightly lower profile. We're talking 1mm at best. This might be okay for some very light applications but trust me, these are NOT the droids you're looking for, err I mean you want the regular dual lock tape.

I got this as an alternative to velcro, and I'm using it to fix things to the desk, such as headphone stands, phone/tablet stands, keyboard and mouse wrist rests, etc. These lock much tighter than velcro, and when they come off, there isn't that horrible clinging rip you get with velcro, as if you're tearing something and breaking it. Instead, the response is very snappy--it comes off in a snap and it locks in a snap. And it won't get weak like velcro because it doesn't rely on tiny little threads that could break with each rip.

The holding power of this is unbelievable!!! I used it to attach a shell holder to my shotgun which is supposed to be screwed on, I have Stevens and so no one may accessories for it. And it will only come off if I pull REALLY hard, 50% of people I have shown it too can't get it off. I can believe how well the adhesive holds too!!!

Dual lock has 10x the strength of sticky-back velcro and lasts longer. Buy this instead. I have used Dual Lock for a few years and some of the original pieces I put down are still in use.

I purchased this to use on various items throughout my motorcycle and cars. It works great and holds everything in place without the bulky thicker stuff. Adhesive is very strong and holds to almost anything as long as it's clean. I may need more soon.

If you've never tried dual lock before and are still using old school fuzzy velcro...I feel sorry for you! This stuff is awesome. One material (never have too much of one and none of the other) that attaches to itself without wearing down over time. Seems to hold tighter than traditional velcro. Sticky backing is great and semi permanent. I've been able to pull it off with some effort. I'm still finding uses for this roll, 10 ft is a lot of velcro tape!

Just like the previous reviewer stated, this is not anywhere near as strong as the normal stuff. There's no point in buying expensive dual lock tape if you're not getting the super hold. You might as well buy velcro.
