It offers greater design flexibility, faster product assembly, smoother and cleaner exterior surfaces and improved product performance in many applications. The fastener consists of continuous polyolefin strips with polyolefin stems having a mushroom shaped top. The mushroom heads allow the fasteners to easily slide over each other allowing positioning of parts before they are snapped together creating a firm fastening attachment. Open and close instantly by simply pulling the interlocking strips apart. The adhesive attaches to metal, plastic, and most rigid or flexible surfaces. Resists solvents, moisture and plasticizers. Also resists heat up to 200 degrees. 1" wide x 4' long roll. Type 250 (approximately 250 stems per square inch). Serves as a great addition to any pedal board!

I am sure you can use it on clothing but I am afraid it may be too thick and too rigid for that purpose. **Q: Does the adhesive stick to wood very well?** A: I purchased it to apply to our outside canopy. Didn't work too good. However, I've used it on wood and plastic and it's still holding. **Q: Can i use this to attach a strobe light to my dji mini three pro drone?** A: Hard to say. Depends on the weight of the strobe. I can say that this stuff has a lot more holding power than Velcro. **Q: No se adhiere a plástico en interior carro** A: Dual Lock should adhere to the plastic interior of a car. Do keep in mind that it will likely leave a residue or discoloration when removed from the interior of a car so be cautious where you place it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Number Plates *by T***A on 25 September 2025* Yeah, it's doing the job so far! satisfied ### ⭐⭐⭐⭐⭐ Strong *by R***9 on 3 August 2025* Amazing stuff - clean the surface - stick it on - wait a bit to cure and it’s unbeatable.
