Lowell LPR Series Portable AV Rack Welded Steel Mobile Rack | 21U x 22"D | Plexiglass Door

The Lowell LPR Series is engineered for AV integrators and production teams who need a durable, mobile rack solution that can withstand the rigors of field deployment and permanent installation alike. Built from 16-gauge welded steel with a 14-gauge base reinforced at every load-bearing junction, these racks deliver a 900 lb. load capacity that handles the heaviest DSPs, amplifiers, and processing gear without compromise. The fully-welded construction eliminates the flex and rattle common in bolt-together alternatives, making the LPR Series a reliable choice for touring rigs, house-of-worship installs, corporate AV buildouts, and broadcast infrastructure.

The series spans multiple rack space and depth configurations to match the scale of any system, from compact 14U deployments to larger 21U and 24U builds, with depth options to accommodate shallow or deep equipment. Front door options include smoked plexiglass for visibility into the rack, solid steel for security-focused environments, and fully vented steel for thermally demanding gear. All configurations ship with four heavy-duty swivel casters for easy repositioning on the floor, recessed side handles for transport, and a keyed-lock door for access control. Rear vented steel doors, top and bottom vents on the welded sides, and removable combination knockout panels in the rear give integrators flexible cable management and airflow routing without field fabrication.

One pair of adjustable 10-32 tapped mounting rails comes standard, and the black-textured powder-coat finish provides a professional appearance that holds up in working environments. Certain configurations include an overhanging laminate top with rubber edge molding as a built-in feature, while other variants offer it as an optional upgrade. This range sits above lightweight ATA-style cases in structural integrity and closer to fixed-install rack furniture in construction quality, while retaining the mobility that installed racks cannot provide.
