Lowell SDP Series solid steel side panels are purpose-built for integrators and AV installers working with Lowell 22-inch and 23-inch wide rack enclosures. Constructed from U.S. steel and finished with a black wrinkle powder epoxy coating, these panels deliver a professional, consistent appearance in permanent installed AV environments such as equipment rooms, control rooms, and distributed audio/video systems. Compatible with Lowell rack series LGR, LSGR, and LGNR, the SDP panels are sized and fitted to match specific rack configurations. Consult individual rack spec sheets to confirm the correct size for each application. The panels ship in pairs, and larger configurations include four pieces total, two per side, to allow practical handling and installation in tight spaces without sacrificing a finished look. For integrators who need a clean enclosure solution that matches existing Lowell rack infrastructure, the SDP Series offers purpose-matched steel construction that generic aftermarket panels cannot match. The integral handles on each panel further distinguish this line from flat-sheet alternatives, supporting both installation ease and long-term serviceability in high-density equipment rooms.
