The 1431-20BK3 is a satin black steel bottom plate for the 17 in x 4 in size of the 1441 Series chassis. Paired with the 1441-20BK3 satin black chassis, it gives builders a fully black, long and shallow enclosure base for full-width electronics.
The plate is 17 in x 4 in x 0.04 in (432 mm x 102 mm x 1 mm), and the drawing specifies the bottom plate as 0.036 in steel. It is finished in satin black powder paint and punched with 4 holes of 3/16 in diameter; the chassis provides 1/8 in holes to allow installation.
