The 1590Z164PL is the inner mounting panel for the 1590Z164 diecast aluminum enclosures, the long, narrow box that measures 14.17 in (360 mm) long, 4.80 in (122 mm) wide and 3.15 in (80 mm) deep. It fits the natural 1590Z164, the textured black 1590Z164BK and the gray 1590Z164GY, and is meant for engineers who need a long strip of mounting area for boards or terminals inside a sealed housing.

Made from 16 gauge galvanized steel, the panel measures 13.6 in x 4.08 in x 0.06 in (345 mm x 104 mm x 2 mm) on the part page. The drawing dimensions the outline at 345.31 mm [13.60 in] by 103.68 mm [4.08 in], the same figures listed as the maximum P.C. board size for the 1590Z164.

The panel sits on the enclosure's internal mounting shelf. The ordering table lists SCGM6-20 as the extra panel screws for the 1590Z164 size. The panel is sold separately, ships in shrink wrap, and has a shipping weight of 1.15 lbs (0.52 kg).

The 1590Z164PL is RoHS and REACH compliant, with UNSPSC code 39121301. Mounting components on the panel outside the box keeps drilling and wiring off the enclosure itself.
