Atlas Sound PFD21 – 1" Plexiglass Door for 21RU 100/200 Series Racks

Product Overview

The Atlas Sound PFD21 is a 1-inch deep scratch-resistant acrylic plexiglass front door for 21RU Atlas Sound 100 Series and 200 Series rack cabinets. Like all PFD Series doors, the PFD21 uses the gripsert mounting hardware integrated into these cabinet lines, allowing tool-free installation on fully populated racks without disrupting installed equipment. This 21RU rack door is the correct-fit option for installers who need a clear protective front panel on a 21-unit rack enclosure.

Product Description

The PFD21 plexiglass door provides a clear view of installed equipment while protecting the rack face from dust, accidental contact, and tampering. The 1-inch depth profile adds minimal projection to the front of the cabinet and is suitable for installations with limited clearance requirements. The scratch-resistant acrylic material maintains optical clarity over time without the yellowing or brittleness associated with lower-grade plastics. At 36 3/4 inches tall and 20 inches wide, the PFD21 covers the full front face of a 21-rack-unit cabinet. The gripsert mounting system eliminates conventional fastener hardware from the installation process—the door engages directly with receiver hardware built into the cabinet frame, making it removable and reinstallable repeatedly without tools. This feature is particularly useful in environments where the rack requires regular access but a closed, professional appearance is needed when not in service. The PFD21 ships ready to install as a complete door assembly. It is sold separately from the rack cabinet and is available for purchase when adding a door to an existing installation or when specifying a new rack with a clear front panel from the outset.
