We use 3M™ Dual Lock™ as an alternative to traditional hook and loop fastener for securing batteries and other onboard equipment.
According to the 3M, the strongest connection is made by combining a piece of 250 stem density with a piece of 400. Note that only the 250 is rated to mate with itself, so if you only buy one material, buy the 250. If you're after the ultimate lock, we recommend 250 on the batteries and 400 on the machine.
Type 400 stem density polyolefin fastener with mushroom shaped stems backed with a white, general purpose acrylic pressure sensitive adhesive. Unlike hook and loop, you use the same material on both sides and squeeze together until it 'clicks'.
Expensive but effective.
Contains one 12" / 30cm strip (1" wide)
