2.0 MAJOR COMPONENTS
A Knurr DCM may have any or all of the components addressed in this section, depending on its
configuration.
2.1 Frame
The base of all Knurr DCM products is the frame. The Knurr DCM features a fully assembled,
extruded aluminum frame with a patented T-slot that permits many of the cabinet’s tool-less
mounting features.
The racks can accommodate shelf- or rack-mounted equipment on 19-inch (483mm) adjustable rails.
See Knurr DCM model numbers on page 28 and illustrations for measurements of different
models.
Cutouts in the top covers permit customer cable entry. The top of the Knurr DCM also is drilled for
mounting a Liebert XDV top-mount cooling unit.
2.2 Enclosure
Exterior components of the Knurr DCM are painted black (RAL 7021)

All doors are framed from sheet metal and have hexagonal perforations leaving 83 percent of the door
open to airflow for efficient cooling. A two-point latch and push button lock come standard.
Doors are available in single- or dual-door designs for easier access. All doors are removable and
single doors are designed for reversible (left/right) hinging (see 3.7.1 - Remove the Door and 3.7.2 -
