1598PLFBK is a pair of black plastic end panels for Hammond 1598F 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 1598F 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 1598F size that black plastic set is 1598PLFBK, while the aluminum alternative is 1598PLF-AL.

The series table lists the matching 1598F enclosures as 1598FBK (flame retardant, black), 1598FGY (flame retardant, gray), 1598FSGY (general purpose, gray) and 1598FSGYPBK (general purpose gray enclosure with black plastic panels). The enclosure measures 9.84 in (250 mm) long, 6.26 in (159 mm) wide and 1.61 in (41 mm) deep. The 1598F is a 250 mm x 159 mm case with a low 41 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.

1598PLFBK is RoHS and REACH compliant and ships in a bag with a shipping weight of 0.04 lbs (0.02 kg). Tilt bail kit 1598TH1 is listed for the same enclosure size.
