The 1441-34BK3 is the satin black version of the 17 x 12 x 2 in steel chassis in the 1441 Series. Its broad 432 x 305 mm footprint and 51 mm height make it a practical low profile base for tube and vintage-style electronic projects when you want a dark powder painted finish instead of grey.

The chassis is spot welded from 18 gauge steel, specified on the drawing as 0.048 in (1.22 mm) material, which is heavier than the 20 gauge used on the smaller 1441 sizes. The drawing lists an inner box of 429.36 mm [16.90 in] length, 302.36 mm [11.90 in] width and 48.36 mm [1.90 in] height, and the assembled height with a bottom plate is 51.71 mm [2.04 in].

For a matching underside, the ordering table pairs this chassis with the 1431-34BK3 satin black bottom panel, with the gray 1431-34 as an alternative; the bottom plate is 0.036 in steel. Plates mount through the chassis's 1/8 in holes and are punched with four 3/16 in diameter holes. Black 1421J6BK or natural 1421J6 6-32 x 1/4 in self-tapping screws come in packages of 6. No perforated cover is listed for this size, and hardware and rubber feet are sold separately.

Factory modification (milling, drilling, printing) is available, along with STEP or IGES solid models. The 1441-34BK3 is RoHS and REACH compliant, ships shrink wrapped and has a shipping weight of 4.29 lbs (1.95 kg).
