The 1411FBSU is a flanged utility case in unpainted, natural-finish aluminum from the 1411 series. The flanged bottom provides wall-mounting tabs, making it a practical choice for OEM engineers, electricians and technicians who want a bare-metal enclosure they can drill, mount and finish to suit their project. Nominal size is 8 x 4 x 3 in (203 x 102 x 76 mm).

Construction is two pieces: a flanged bottom and a cover, both made from 0.04" (1.02 mm) aluminum panels. Each purchased assembly includes the flanged bottom, the cover and four self-tapping cover screws. Replacement cover screws are available as 1421J6, a package of six 6-32 x 1/4" plated self-tapping screws, and 1421J6BK supplies the same screws in black.

According to the drawing, the assembled box measures 202.84 mm [7.99 in] long, 101.24 mm [3.99 in] wide and 77.80 mm [3.06 in] high, with an overall length of 231.78 mm [9.13 in] across the flanges. Usable inside space is 200.81 mm [7.91 in] long by 96.39 mm [3.80 in] wide by 75.77 mm [2.98 in] high. Shipping weight is 0.5 lbs (0.23 kg).

Because the aluminum is left unpainted, it is protected through manufacturing and shipping by a plastic film cover that keeps the finish clean and doubles as a removable drilling template. Hammond also offers factory modification such as milling, drilling and printing, and solid models are available in STEP or IGES.

The part is RoHS and REACH compliant and ships shrink wrapped. Other versions of the same 8 x 4 x 3 in size in the ordering table are 1411S (aluminum gray), 1411SU (aluminum unfinished), 1411FBSBK (aluminum black w/ flanges).
