Ergodyne - EGO19169 Squids 3136 Bar-code Scanner Adapter Straps are designed for use with the Squids 3135 Bar-code Scanner Belt with Hook to keep bar-code scanners secure and accessible. Two loop attachments on the strap connect to small captive holes built into bar-code scanners, enabling scanners to hang comfortably on the belt hook when not in use. Industrial-grade strap with modular buckles enables quick interchange for those who frequently use multiple cordless scanners while others are recharging, eliminating the need to switch out the loop attachments on every exchange. When used without the Scanner Belt with Hook, the adapter strap provides a convenient carrying handle. Handwash and dry with mild soap and water.
