The Hammond 1444-45351 is a compact 4.5 x 3.5 in chassis only 1 in high, one of the smallest sizes in the 1444 Series table. It is an open-bottom, natural-finish aluminum chassis from the 1444 Series, aimed at electronics hobbyists, audio and instrument builders and OEM engineers who need a rigid, easy-to-machine platform for mounting transformers, sockets, controls and circuit boards.
The chassis is spot welded for heavy-duty construction and is formed from 0.040" aluminum (0.04 in (1 mm) in the series table) in a natural aluminum finish. Material is listed as aluminum and the part is RoHS and REACH compliant.
Per the series table the 1444-45351 measures 4.50 in (114 mm) wide, 3.50 in (89 mm) deep and 1.00 in (25 mm) high. The drawing gives an inner box width of 86.86 mm [3.42 in], inner box length of 112.26 mm [4.42 in] and inner box height of 23.37 mm [0.92 in]. Its matching bottom plate is the 1434-4535.
The bottom plate (1434-4535) is optional and sold separately; optional bottom plates are punched with 4 holes of 3/16 in diameter. Bottom plate hardware is not provided: order part 1421J6, a package of 6 plated 6-32 x 1/4 in self-tapping cover screws. Note that the 1451 Series steel chassis covers are not compatible with this series.
The enclosure can be factory modified (milling, drilling, printing), and solid models are available in STEP or IGES format for layout work before you cut metal.
