3M Dual Lock, Low Profile, Clear, 1" wide, sold in 1 foot lengths
Great for securing items in the cockpit. This is the thin version. It does not hold with as much force and is not as good in high-temperature applications as the other options below, but it is half as thick as the standard Dual Lock products. It works great in a glider cockpit, but not as well as the options below. Bonds well to metals, glass, many plastics (polypropylene, polyethylene, polycarbonate, ABS) powder coated paints an dmedium to low surface energy materials.
