Easy-to-use, inexpensive key-lock system that secures most common Scan Hooks, and even retrofits existing hooks in-store. Install locks alone to retrofit your existing inventory of Scan Hooks, or full lock-and-hook combinations in your choice of hook and label holder styles. ScanLock secures scan hooks with wire diameters ranging from 0.212 to 0.250 and approximately 1 frontwire spacing. Minimal cost to implement into any plan-o-gram, unlike other solutions.
