The 1451-16BK3 is the satin black perforated steel chassis cover for the 10 x 6 in footprint of the 1441 Series. According to the ordering table it serves the 1441-15 (1 in tall) and 1441-16 (2 in tall) chassis and their BK3 versions, and it is also listed alongside the 1441-16BK3CWW satin black chassis with walnut sides, making it a natural match for a black, wood-trimmed build.

The listed size is 10 in x 6 in x 5.2 in (254 x 152 x 132 mm).

It is 20 gauge welded steel with a perforated steel cover, 0.91 mm [0.036 in] thick.

The cover comes with four #6-32 x 1/4 in self tap screws, which attach through four 4.76 mm [0.188 in] diameter holes. For the underside, the 1431-16BK3 satin black bottom panel is listed on the same rows, with the gray 1431-16 as an alternative.
