The 1441-6BK3 is a compact 4 in x 4 in x 2 in steel chassis finished in satin black. As the smallest size in the 1441 Series ordering table, it suits small circuits, accessory boxes and classic or tube-style projects where a builder wants a dark finish rather than the grey 1441-6.
Construction is spot welded 20 gauge steel, with the drawing giving the material as 0.036 in steel, and the whole chassis is finished in satin black powder paint. Nominal size is 4 in x 4 in x 2 in (102 mm x 102 mm x 51 mm).
The chassis includes 1/8 in holes to allow the optional bottom plate to be installed. Hardware is not provided; the drawing lists 1421J6BK black and 1421J6 natural finish cover screws, six 6-32 x 1/4 in self-tapping screws per pack. Rubber feet are sold separately. Enclosures can be factory modified (milling, drilling, printing) and solid models are available in STEP or IGES. The 1441-6BK3 is RoHS and REACH compliant, ships shrink wrapped and weighs 0.55 lbs (0.25 kg).
