The 1456KE3WHBU is a wide, shallow 30-degree sloped console: 10.00 in (254 mm) across but only 5.50 in (140 mm) deep, with a 3.00 in (76 mm) rear height. It suits panel layouts that run side to side, such as rows of switches, meters or indicators, where desk depth is limited. This version pairs a contempra grey (beige) top panel with the series' textured blue case.

The front edge stands 1.10 in (28 mm) high. Hammond's nominal size is 5.5 in x 10 in x 3 in (140 mm x 254 mm x 76 mm), and the drawing shows overall extents of 257.18 mm [10.13 in] wide, 146.05 mm [5.75 in] deep and 81.43 mm [3.21 in] high. It has the shallowest depth of the 10 in wide models in the 1456 table.

The case is 12 gauge aluminum, 0.081 in (2 mm) thick, and the top panel is 14 gauge aluminum, 0.064 in thick. It is sold pre-assembled; the purchased assembly includes the case, cover, 4 cover screws and 4 self-adhesive rubber feet, and the case is vented on the rear and bottom. Hammond recommends a cover screw torque of 150-175 cN-m (13.3-15.5 lbf-in).

The part is RoHS and REACH compliant, ships shrink wrapped at 1.5 lbs (0.68 kg), and can be factory modified (milling, drilling, printing) on request. Solid models are available in STEP or IGES, and replacement cover screws are sold as 1421J6 (natural finish) or 1421J6BK (black), with spare rubber feet as 1421T3.
