The 1441-24 is a 12 in x 8 in x 3 in (305 mm x 203 mm x 76 mm) steel chassis finished in ASA 61 smooth grey powder paint. It is the ASA 61 grey version of this size; the same chassis is offered in satin black as 1441-24BK3, and with real walnut sides as 1441-24BK3CWW. It suits electronics hobbyists, audio and tube-equipment builders, and OEM engineers who need an open-bottom metal base for mounting components.
Construction is spot welded, heavy-duty 20 gauge steel; the drawing specifies 0.036 in steel for both the chassis and the optional bottom plate. The inner box measures 302.97 mm [11.93 in] long, 201.37 mm [7.93 in] wide and 74.37 mm [2.93 in] high, which is the space available for transformers, boards and wiring. Shipping weight is 2.51 lbs (1.14 kg).
This 3 in tall version of the 12 in x 8 in footprint shares its bottom panel and perforated cover part numbers with the 2 in tall 1441-22. All components are sold separately. The matching ASA 61 grey bottom panel is 1431-22 (1431-22BK3 in the other finish); bottom plates are punched with 4 holes of 3/16 in diameter and the chassis includes 1/8 in holes to accept them. A ASA 61 grey perforated chassis cover, 1451-22, is listed for this size (1451-22BK3 in satin black).
