The 1431-22BK3 is a satin black steel bottom plate for the 12 in x 8 in chassis size in the 1441 Series. It is well matched to the satin black chassis with walnut sides (1441-22BK3CWW and 1441-24BK3CWW), and it also fits the plain grey and satin black versions, giving vintage-style tube builds a finished black base.
The plate is 12 in x 8 in x 0.04 in (305 mm x 203 mm x 1 mm). The drawing calls out 0.036 in steel for the bottom plate, and the finish is satin black powder paint. It is punched with 4 holes of 3/16 in diameter, and the chassis includes 1/8 in holes to allow installation.
