The Squids 3140 Bar-code Scanner Lanyard Attachments are compatible with Squids 3138 and 3142 Scanner Harnesses. They easily attach to cordless bar-code scanners, allowing the scanner to hang on the hip when not in use and preventing drops that could cause damage. Each attachment is secured to the harness by looping a webbing strap through a D-ring. Adjustable, scanner lanyard attachments enable quick interchange for those who frequently use multiple cordless scanners while others are recharging, eliminating the need to switch out the loop attachment on every exchange. They are ideal for attaching to cordless bar-code scanners for work in warehouses, distribution centers, material inventory on construction and steel sites, airline baggage scanning and grocery/personal shopping.
