Hammond 1441-18 13.5x5x2 in ASA 61 Grey Steel Chassis, 20 Gauge

The 1441-18 is a 13.5 in x 5 in x 2 in (343 mm x 127 mm x 51 mm) steel chassis finished in ASA 61 smooth grey powder paint. It is the ASA 61 grey version of this size; the same chassis is offered in satin black as 1441-18BK3. 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 341.07 mm [13.43 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 1.53 lbs (0.69 kg).

The long, narrow 13.5 in x 5 in footprint suits a row of components laid out end to end; the ordering table lists no perforated chassis cover for this size. All components are sold separately. The matching ASA 61 grey bottom panel is 1431-18 (1431-18BK3 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.

• Hardware is not provided: order 1421J6 (natural finish 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.
