The 1451-10BK3 is a satin black perforated steel chassis cover sized for the 8 x 4 in chassis of the 1441 Series. The ordering table lists it for the 1441-9 (1 in tall) and 1441-10 (2 in tall) chassis in both grey and BK3 satin black, so it can close off the top of a small chassis build with a vented, dark-finished cover.

The part record gives its size as 8 in x 4 in x 5.2 in (203 x 102 x 132 mm). On the drawing, the top measures 205.41 mm [8.087 in] long, the bottom 203.58 mm [8.015 in], the width 101.60 mm [4.000 in] and the height 132.59 mm [5.220 in]. Construction is 20 gauge welded steel with a perforated steel cover, and the typical material thickness is 0.91 mm [0.036 in].

Attachment is straightforward: four #6-32 x 1/4 in self tap screws are supplied, and the drawing shows four 4.76 mm [0.188 in] diameter holes. For a matching black underside, the same chassis rows list the 1431-10BK3 satin black bottom panel.

The cover can be factory modified (milling, drilling, printing), and solid models are available in STEP or IGES format. The 1451-10BK3 is RoHS and REACH compliant, ships in a box and has a shipping weight of 1.43 lbs (0.65 kg). A grey version is available as 1451-10.
