Having a flashlight or a first aid kit ready to pull off the wall just when you need it is a huge advantage, but most hook and loop fasteners (like Velcro) wear out too quickly, letting your stuff fall off at random moments. But 3M now offers an updated solution: Dual Lock tape. It’s stronger, more heat resistant, and makes a satisfying clunk that lets you know that things will stay where you put them.
You’ve probably seen Dual Lock if you live in a state that operats an automatic toll collection system — it’s what holds the transponder to windshields.
Dual Lock is self mating. It relies on twin sides containing hundreds of interlocking mushroom shaped nodes. This is what gives it five times the strength of hook-and-loop fasteners as well as a “no wiggle” hold. It ships in several different lengths as well as different densities of nodes per square inch, but a basic 10′ roll of adhesive-backed 5/8″ goes for about $15.
