The 1441-29BK3 is a 12 in x 10 in x 2 in (305 mm x 254 mm x 51 mm) steel chassis finished in satin black powder paint. It is the satin black version of this size; the same chassis is offered in ASA 61 grey as 1441-29. 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, 252.17 mm [9.93 in] wide and 48.97 mm [1.93 in] high, which is the space available for transformers, boards and wiring. Shipping weight is 2.4 lbs (1.09 kg).
The 12 in x 10 in footprint is the deepest 12 in size in the table, with a dedicated bottom panel and perforated chassis cover. All components are sold separately. The matching satin black bottom panel is 1431-29BK3 (1431-29 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 satin black perforated chassis cover, 1451-29BK3, is listed for this size (1451-29 in grey).
