The NWM18U2536SFLG is an 18U outdoor-rated wall-mount cabinet with a solid, filter-ready door, built for telecom, industrial, utility and edge computing equipment that has to live outside. It is the "F" (filter and rain hood) version of the NWM Series: the door and body include cutouts sized for the NWMFH2 filter and rain hood kit, which is sold separately. Because of the size of the filter/rain hood, a window door is not offered in this configuration.

Construction is 14-gauge welded steel with a sealed and gasketed cabinet design and a locking door for physical security and controlled access. The enclosure is rated UL508A Type 1, 3R and 4 (UL file E65324) for protection against rain, sleet and hose-directed water, and the corrosion-resistant construction and light gray powder coat finish are intended for long-term outdoor durability. The powder coat is GREENGUARD, TSCA and RoHS compliant.

Overall dimensions are 38.95 in (989 mm) high x 25.00 in (635 mm) wide x 37.49 in (952 mm) deep, with 35.00 in (889 mm) of usable mounting height and 27.00 in (686 mm) of usable mounting depth thanks to the swing-out function. Two pairs of adjustable 10-32 threaded mounting rails on 19" EIA centers provide 18U of standard rack mounting, and a starter hardware pack with SCREW1032-50 screws is included. Load capacity is 350 lb, and the cabinet is seismic rated to a 200 lb (90.72 kg) dynamic load (Ip = 1.5).

Wall mounting hardware is not included, and all accessories are sold separately. Optional inner panels are available in aluminum (WRPS18UNF) or steel (WRPS18UWH). NWM18U2536SFLG is manufactured in Canada, is TAA- and USMCA-compliant, and meets PCI DSS requirements for regulated installations.
