Zippered storage pouches are mounted inside rackmount case lids. Pouches are typically used for storing cables, keyboards, removable casters, manuals and other loose items. They are durably sewn, using black nylon fabric. Pouches are available to fit a range of rack heights, including small (3-5U), medium (6-8U) and large (9-20U). Pouches are attached using snaps, which allow for easy removal and reinstallation, or they may be permanently installed by ECS using rivets.
