Atlas Sound 124-18 – 24RU Stand-Alone Floor Rack Cabinet

Product Overview

The AtlasIED 124-18 is a commercial-grade 24RU stand-alone floor rack cabinet built for AV equipment installations in permanent commercial spaces. Constructed from welded 16-gauge cold-rolled steel with UL 1678 listing, this floor-standing rack cabinet provides a secure, ventilated enclosure for rack-mount audio, video, and networking gear. The 18.5-inch depth accommodates most full-depth rack-mount equipment, and the fixed 10-32 tapped EIA-standard rails ensure broad compatibility with industry-standard hardware.

Product Description

The Atlas Sound 124-18 floor rack is part of the 100 Series Cabinet line, engineered for permanent commercial AV installations where security, airflow, and cable management are priorities. The cabinet arrives welded and assembled for immediate deployment, reducing on-site labor. The locking rear door uses quick-release spring hinges that rotate 180 degrees, allowing right- or left-hand opening to suit any room layout. A flush door handle and cylinder lock secure rear access, while a separate front door (ordered separately) can be keyed differently for added security.

The 100 Series cabinet features a 6RU top panel opening that accommodates the optional EFP Series fan kits for active cooling, or can be partially covered with the ISOPANEL for non-conductive cable access. Conduit arrays on top and bottom surface panels include standard 1-inch and concentric 1/2-inch to 3/4-inch knockouts, streamlining conduit runs to below-floor raceways or overhead cable trays. Perforated vents on the front, sides, and rear door promote passive convection cooling for heat-generating rack-mount amplifiers, processors, and network switches. The cabinet exterior is phosphate pre-treated and finished in textured black epoxy (#962) for durability in commercial environments. Rails are recessed 5/8 inch and manufactured to E.I.A. standards, supporting standard 10-32 rack hardware throughout all 24RU positions.
