3133 Bar Code Scanner Lanyard Loop Attachments are designed to work with Squids Bar Code Scanner Harnesses and Sling Lanyards (none included). Each loop attachment connects to small, captive holes built into cordless scanners, allowing them to hang comfortably on your hip when not in use. Attachments also prevent the scanner from being dropped, causing damage to the scanner, other equipment/items or workers. Small, female buckle clips into a corresponding male buckle on the harness or sling. Loop attachments enable a quick interchange between scanners, eliminating the need to switch out the attachment on every exchange. Heavy-duty, industrial-grade material is built for harsh conditions. Handwash and dry the attachments with mild soap and water to enhance longevity.
