Trial Bag 2 Rolls Dual Lock Ind. 250/250 rubber

Mushroom shaped stems on one side of the fastener interlock with identical ones on the other side for 5x greater closure strength than hook and loop closures, yet peel apart for opening. Quickly and easily adjust or reattach until precisely aligned then "snap" into place. Choice of stem density per square inch (170, 250, 400) allows you to adjust the closure strength. Low profile option has half the thickness. Lose the screws to improve design appearance and maintain surface integrity.

TB3540, the most popular DualLock trial bag, features a rubber based adhesive on the back of a black, polypropylene reclosable fastener. 250 stems per square inch. .23 inch engaged thickness. Closure life 1,000.
