Organized and Compact. The OC Cases are an ideal add on for our larger tool bags or as a stand alone storage solution. Designed for versatility, each case provides a semi rigid protective shell for specialized tools & electronics. With a number of available V-SWAP panels, each case can be outfitted with up to 3 different organizational components. The medium sized OC140 includes 2 V-SWAP panels (a panel with elastic tension straps (Tension Strap Panel) and a removable Zippered Parts Folio bag) and an exclusive double gated carabiner that can connect in multiple locations.
