3M Dual Lock, Black, 1" wide, 400 stems/inch, sold in 1 foot lengths
Great for securing items in the cockpit. Works well with 250 stems/inch Dual Lock. It does not work as well with itself
. It offers better high temperature performance than the low-profile option above and also offers higher holding strength. Bonds well to metals (aluminum, stainless steel), glass, plastics (acrylic, polycarbonate, ABS) and paints.

Sold by the foot - one side only (ordering 1 foot gets you 6 inches of both sides)

See option below for ordering a pair with one side having 250 stems/inch and the other side having 400 stems/inch. That is the option with the strongest holding strength.
