1598PLJBK is a pair of black plastic end panels for Hammond 1598J ABS instrument enclosures. It is a replacement or spare front-and-rear panel set for engineers, technicians and product builders who need to swap, customize or re-machine the end panels of a 1598J case.

The panels are molded from ABS plastic in black with a UL94 V-0 flame rating. The 1598 Series notes that replacement natural finish aluminum and black plastic end panels are available, with the compatible panel set shown in the part number table; for the 1598J size that black plastic set is 1598PLJBK, while the aluminum alternative is 1598PLJ-AL.

The series table lists the matching 1598J enclosures as 1598JBK (flame retardant, black), 1598JGY (flame retardant, gray), 1598JSGY (general purpose, gray) and 1598JSGYPBK (general purpose gray enclosure with black plastic panels). The enclosure measures 11.02 in (280 mm) long, 7.87 in (200 mm) wide and 2.99 in (76 mm) deep. The 1598J is 280 mm x 200 mm with a 76 mm depth.

When cutting openings for switches, displays and connectors, note that Hammond's chemical resistance statement for the series advises against acetone, ketones, thread locking compounds, cutting or tapping fluid and strong solvents on its plastic parts; an air blast is recommended to clear chips after modification.

1598PLJBK is RoHS and REACH compliant and ships in a bag with a shipping weight of 0.1 lbs (0.05 kg). Tilt bail kit 1598TH2 is listed for the same enclosure size.
