1598PLBBK is a pair of black plastic end panels for Hammond 1598B 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 1598B 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 1598B size that black plastic set is 1598PLBBK, while the aluminum alternative is 1598PLB-AL.

The series table lists the matching 1598B enclosures as 1598BBK (flame retardant, black), 1598BGY (flame retardant, gray), 1598BSGY (general purpose, gray) and 1598BSGYPBK (general purpose gray enclosure with black plastic panels). The enclosure measures 5.28 in (134 mm) long, 5.31 in (135 mm) wide and 2.01 in (51 mm) deep. The 1598B is the shortest case in the table at 134 mm long, with a 51 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.

1598PLBBK is RoHS and REACH compliant and ships in a bag with a shipping weight of 0.04 lbs (0.02 kg).
