The 1441-40BK3 is the satin black edition of the 17 x 14 x 4 in (432 x 356 x 102 mm) steel chassis in the 1441 Series. Its large footprint and 4 in height, combined with a dark powder painted finish, suit tube, vintage-style and other electronic builds that need plenty of room above and below the deck.

The chassis is 101.60 mm [4.00 in] tall and 102.51 mm [4.04 in] with a bottom plate in place.
The 1431-38BK3 satin black bottom panel is listed as the matching closure, with the gray 1431-38 as an alternative. Bottom plates are 0.036 in steel, punched with four 3/16 in diameter holes, and install through the 1/8 in holes provided in the chassis. Use 1421J6BK black or 1421J6 natural finish 6-32 x 1/4 in self-tapping screws, sold in packages of 6.
