Plexiglass Door for WMA, 100 & 200-Series Racks (21 RU)

Ideal Use Cases

The AtlasIED PFD21 is intended for installations that require a plexiglass door on a 21 RU WMA series equipment cabinet. Its product naming also identifies it for 100- and 200-Series racks, making it a specifically designated rack accessory rather than a general-purpose panel. This model is relevant when the required cabinet capacity is 21 rack units and the installation calls for a door with a depth of 1 inch. Before ordering, match the WMA cabinet family, rack series, and 21 RU capacity to the planned installation, as compatibility with other rack sizes or cabinet families is not stated in the supplied product information.

Why Choose This Model

The PFD21 has a clearly documented physical format that makes compatibility checks straightforward. It measures 36 3/4 inches high, 20 inches wide, and 1 inch deep. Metric measurements are also provided: 93.345 cm high, 50.8 cm wide, and 2.54 cm deep. These dimensions give installers concrete values for comparing the door with the intended rack and available installation clearance. The product also carries a warranty period of 60 months from the date of purchase. Its defined 21 RU capacity and stated use with WMA series equipment cabinets help distinguish its intended application within an equipment-rack project.

Installation and Integration

This door is described for use with 21 RU WMA series equipment cabinets and is identified for 100/200 racks. During project planning, account for the stated 1-inch depth and verify that the cabinet is the correct 21 RU model before installation. The listed height and width should also be compared with the selected enclosure: 36 3/4 inches by 20 inches. The supplied data does not identify mounting hardware, hinge orientation, locking or latching features, required tools, or included accessories. No in-box contents are specified. Those details should therefore be confirmed separately when preparing the complete rack installation or determining whether additional components are required.

Performance Highlights

As a rack accessory, the PFD21 is defined by its physical configuration and stated cabinet application rather than electronic performance specifications. Its primary characteristics are its plexiglass construction description, 21 rack-unit format, 1-inch depth, 20-inch width, and 36 3/4-inch height. The listed shipping weight is 23.00 pounds, or 10.43 kilograms, which is useful for shipment planning and handling estimates without being presented as the installed product weight. The technical data also records “Safety Listed” with a value of 1680. Because no listing organization, certification name, or standard is supplied, that value is retained without further interpretation.

What Makes It Different

The defining combination for this model is specific: a plexiglass door, a 21 RU size, a 1-inch depth, and stated use with WMA series equipment cabinets and 100/200-Series racks. This focused configuration makes the PFD21 easy to identify when a project specification calls for that exact door format. It is listed as a door for compatible equipment cabinets, not as a complete rack or cabinet. The source information does not state a finish, color, lock type, ventilation design, hinge configuration, or environmental rating, so no assumptions about those characteristics are included. The product is presented according to its documented dimensions and rack compatibility.

Final Assessment

The AtlasIED PFD21 is a purpose-identified 21 RU plexiglass door for WMA series equipment cabinets and 100- and 200-Series racks. Its 36 3/4-inch height, 20-inch width, and 1-inch depth provide the essential measurements needed for specification review, while the listed 23.00-pound shipping weight supports delivery planning. A 60-month warranty from the date of purchase is documented. This model is an appropriate selection when the project requires the stated rack families, 21 RU format, and shallow 1-inch door depth. Confirm unspecified mounting and accessory requirements as part of final system planning.
