The 1434-29 is a natural-finish aluminum bottom plate (Aluminum Chassis Cover 12 x 10) that closes the open underside of a Hammond 1444 Series aluminum chassis. It suits builders of tube, audio and classic or vintage-style equipment who want a finished base on a 12 x 10 in spot-welded aluminum chassis.

The description identifies this as a 12 x 10 in cover; the part page gives no separate size figure, but the ordering table matches it to the 12 x 10 in chassis. Shipping weight is 0.57 lbs (0.26 kg). The 1444 Series ordering table assigns this one plate to 2 chassis that share the same 12.00 in (305 mm) by 10.00 in (254 mm) footprint: 1444-29 and 1444-12103. They differ only in height (2 and 3 in), and all use 0.05 in (1 mm) aluminum, so one part number covers any of them.

Bottom plates in this series are punched with 4 holes, 3/16" diameter, ready to fasten to the chassis. Hardware is not supplied with the plate: order part number 1421J6 separately, a package of six 6-32 Philips head screws. Note that the steel 1451 Series chassis covers are not compatible with the 1444 Series, so this aluminum plate is the matching base for these chassis.

The 1434-29 is made of aluminum in a Natural Aluminum colour, is RoHS and REACH compliant, and ships in a bag. It carries UPC 623980495002 and UNSPSC 39121301, which makes it simple to reference on purchase orders and in inventory systems.
