The 1411FBDU is a unfinished aluminum utility case with wall-mounting flanges from the 1411-1412 Series, measuring 3.20 in (81 mm) long, 2.20 in (56 mm) wide and 1.60 in (41 mm) high. It gives electricians, OEM engineers and hobbyists a compact metal housing that can be fixed directly to a wall or panel through its flanged bottom.

The D size takes the 3.20 x 2.20 in (81 x 56 mm) footprint of the C size and adds height, to 1.60 in (41 mm), for taller components on the same board area.

Both the flanged bottom and the cover are formed from 0.04 in thick aluminum. This version is left as unfinished aluminum. It is protected through manufacturing and shipping by a plastic film cover that keeps the surface in good condition and also doubles as a removable drilling template.

The purchased assembly includes the flanged bottom, cover and 4 cover screws; the cover fastens with self-tapping screws. Replacement screws are available as 1421J6, a package of six 6-32 Philips head screws. The 1411FBDU can also be factory modified (milling, drilling, printing), and solid models are available in STEP or IGES format for enclosure layout work.

The same 3.20 x 2.20 x 1.60 in size is also offered as 1411D, 1411DU and 1411FBDBK in the other finish and flange combinations. The 1411FBDU is RoHS and REACH compliant, ships in shrink wrap and has a listed shipping weight of 0.13 lbs (0.06 kg).
