The 1431-26 is the ASA 61 smooth grey bottom plate for the 16 in x 8 in footprint of the 1441 Series steel chassis. One part number serves two heights, the 2 in high 1441-26 and the 3 in high 1441-28, so builders working on larger classic or tube-style projects can close either chassis with the same plate.
The part page lists the size as 16 in x 8 in x 0.04 in (406 mm x 203 mm x 1 mm), while the drawing notes the bottom plate is made of 0.036 in steel. It carries an ASA 61 smooth grey powder paint finish and is punched with 4 holes of 3/16 in diameter; the chassis includes 1/8 in holes for mounting it.
The ordering table ties it to the 1441-26 and 1441-26BK3 (16.00 in W x 8.00 in D x 2.00 in H) and the 1441-28 and 1441-28BK3 (16.00 in W x 8.00 in D x 3.00 in H), all 20 gauge steel. The 1441-26 drawing shows an inner box of 404.57 mm [15.93 in] by 201.37 mm [7.93 in] by 48.97 mm [1.93 in] for the assembly. Perforated covers 1451-26 (grey) and 1451-26BK3 (satin black) are listed for this size.
All components are sold separately, including the 1421J6 package of six 6-32 x 1/4 in self-tapping screws. The 1431-26 is RoHS and REACH compliant, ships in a bag and has a shipping weight of 1.27 lbs (0.58 kg).
