Hammond 1441-6BK3 4x4x2-Inch Satin Black Steel Chassis

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).
