The 1441-28BK3 is a 16 in x 8 in x 3 in (406 mm x 203 mm x 76 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 1441-28. 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 404.57 mm [15.93 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 3.09 lbs (1.40 kg).
This 3 in tall version of the 16 in x 8 in footprint shares its bottom panel and perforated cover part numbers with the 2 in tall 1441-26. All components are sold separately. The matching satin black bottom panel is 1431-26BK3 (1431-26 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, 1451-26BK3, is listed for this size (1451-26 in grey).
