## Description

3M Dual Lock Reclosable Fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets They are ideal for both indoor and outdoor applications including, attaching signs, cushions, enclosure and access panels, banners, doors, adjustable shelving, vehicle ceiling panels, furniture seats and backs, and much more As a general rule, four square inches of fastener area per pound of static tensile or shear load to be supported (4in2 and lb) is suggested as a starting point for evaluation More or less area may be needed depending on specific conditions or end use applications Do not use too much of the reclosable fastener or it will be extremely challenging to separate the two parts Pry off with a screwdriver if necessary Customer is solely responsible for evaluating the product and determining whether it is appropriate and suitable for customer’s application

Review: Great Product.. - This is the best velcro on the market as far as I'm concerned. I've used this product for years and has been used for everything from holding toll way transponders to securing electronic equipment (including mounting a computer hard drive inside a server case that was out of available hard drive bays). A little of this stuff goes a very very long way. FYI - Another reviewer stated that their order did not come in the dispensing box as shown in the advertisement. That was not my case. I received it as pictured. BTW - as with anything adhesive and past experience. The best prep is a clean dry flat surface. I always use rubbing alcohol to wipe a surface and another clean paper towel to dry the surface. Sometimes the residual if not wiped with a separate dry towel can affect adhesion.
Review: Pricey, but it sticks to glass in extreme temperatures - This was $75 for the package when I ordered it, which is expensive compared to other "re-closeable fasteners". What sets this apart, though, is that it does live up to its claim to be high temperature. I used this product to fasten a set of emergency response lights to my windshield. Other fasteners I tried came loose within days in the summer. This fastener has been in place for over two years now with no issues. The price is also offset by you not having to use very much to accomplish the job. My Whelen SlimMiser light is held to my windshield with just 3 square inches of the product. Overall, pricey but worth it.
