The Squids 3133 Barcode Scanner Lanyard Loop Attachment Replacements (10-Pack) are designed to work with the Squids Barcode Scanner Harnesses and Sling Lanyards. Each loop attachment connects to small captive holes built into cordless barcode scanners, allowing them to hang comfortably on the hip when not in use. The attachments also prevent the scanner from being dropped, causing damage to the scanner, other items/equipment or workers on the job. Each loop attachment affixes to the lanyard via a small modular female buckle that clips into a corresponding male buckle on the Squids Harness or Sling. These replacement loop 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. Squids 3133 Replacement Loop Attachments are compatible with Squids Barcode Scanner Harnesses (3132 & 3138) and Squids Scanner Sling Lanyards (3134 & 3137).
