Hammond 1441-14BK3 9x5x2 in Satin Black Steel Chassis, 20 Gauge

The 1441-14BK3 is a 9 in x 5 in x 2 in (229 mm x 127 mm x 51 mm) steel chassis finished in satin black powder paint. It is the satin black version of this size; the same chassis is offered in ASA 61 grey as 1441-14. It suits electronics hobbyists, audio and tube-equipment builders, and OEM engineers who need an open-bottom metal base for mounting components.

Construction is spot welded, heavy-duty 20 gauge steel; the drawing specifies 0.036 in steel for both the chassis and the optional bottom plate. The inner box measures 226.77 mm [8.93 in] long, 125.17 mm [4.93 in] wide and 48.97 mm [1.93 in] high, which is the space available for transformers, boards and wiring. Shipping weight is 1.12 lbs (0.51 kg).

The 9 in x 5 in footprint pairs with its own perforated chassis cover from the 1451 series, so the top can be closed off if the build calls for it. All components are sold separately. The matching satin black bottom panel is 1431-14BK3 (1431-14 in the other finish); bottom plates are punched with 4 holes of 3/16 in diameter and the chassis includes 1/8 in holes to accept them. A satin black perforated chassis cover, 1451-14BK3, is listed for this size (1451-14 in grey).

• Hardware is not provided: order 1421J6BK (black cover screws, pkg of 6, 6-32 x 1/4 in self-tapping) to attach the bottom plate.
• Rubber feet are sold separately.
• RoHS and REACH compliant; ships shrink wrapped.
• Can be factory modified (milling, drilling, printing); solid models available in STEP or IGES.
