The 1431-18 is an ASA 61 smooth grey steel bottom plate for the 13.5 in x 5 in chassis in the 1441 Series. That long, narrow footprint suits slim tube and classic-style electronics builds, and this plate closes the chassis underside to finish the enclosure.
The part page gives the size as 13.5 in x 5 in x 0.04 in (343 mm x 127 mm x 1 mm), and the drawing notes the plate is made of 0.036 in steel. The finish is ASA 61 smooth grey powder paint. Optional bottom plates in this series are punched with 4 holes of 3/16 in diameter, and the chassis includes 1/8 in holes so the plate can be fitted.
This plate is listed for the 1441-18 grey and 1441-18BK3 satin black chassis, which measure 13.50 in (343 mm) wide, 5.00 in (127 mm) deep and 2.00 in (51 mm) high in 20 gauge steel. The 1441-18 drawing shows the completed assembly with an inner box of 341.07 mm [13.43 in] long, 125.17 mm [4.93 in] wide and 48.97 mm [1.93 in] high. The ordering table lists no perforated chassis cover for this size.
