Middle Atlantic U3MP – U3 3RU Rack Shelf 36-Piece Master Pack

Product Overview

The Middle Atlantic U3MP is a 36-piece master pack of U3 utility rack shelves, supplied individually packaged on a single skid for AV integration firms that stock shelves as a standard truck and shop item. Each U3 shelf occupies 3RU in a standard 19-inch rack and provides a 14.6-inch deep platform for mounting non-rackmount equipment such as media players, small switchers, modems, and power supplies. For integrators running multiple commercial deployments at once, buying utility rack shelves in bulk eliminates per-unit ordering and keeps every project bin stocked.

Product Description

Utility shelves are among the most consumed accessories in commercial AV installation — nearly every equipment rack includes devices that lack rackmount ears. The U3 utility rackshelf solves that on every job: a 3RU, 14.6-inch deep shelf of welded steel construction with a black powder coat finish that matches Middle Atlantic enclosures and standard rack hardware.

The U3MP master pack format is built for volume buyers. Thirty-six shelves arrive individually packaged on a skid, so warehouse staff can receive one shipment, shelve the cartons, and pull single units per work order without repacking. Individual packaging also means each shelf stays protected until it reaches the job site, whether that is a corporate conference room rollout, a campus standardization program, or an ongoing service contract.

Welded steel construction gives each shelf the rigidity to carry typical AV components without flex, and the powder coat finish resists scratching during transport and installation. Because the U3 is a standard 19-inch rackmount accessory, it installs in Middle Atlantic ERK, SR, BGR, and wall-mount racks as well as other EIA-standard enclosures. Stock the master pack alongside other Middle Atlantic rack accessories from Creation Networks to keep project kitting simple.
