The 1598PLG-AL is the extra aluminum end panel pair for the 1598RGBK, the deep 250 mm shielded instrument enclosure in the 1598R series. Engineers and builders use a spare pair like this to cut new panel layouts without disturbing an existing build, or to replace panels that have been drilled for a previous revision.

Hammond describes the part as an aluminum endplate set: hardware, aluminum end panels, 2-pack. The panels are aluminum in a natural aluminum color. They are packed in a bag, have a shipping weight of 0.08 lbs (0.04 kg), and are RoHS and REACH compliant.

In the ordering table, the 1598RGBK is listed at 250 mm long, 159 mm wide and 75 mm deep - the same footprint as the 1598RFBK but much taller, which is why its panels are a separate part from the 1598PLF-AL. The 1598R series specifies the enclosure's front and rear panels as 1.6 mm (0.064") brushed aluminum with protective paper on one side.

Choose the 1598PLG-AL when the target enclosure is the 1598RGBK. The same table row lists 1598TH1 as the tilt bail kit for that case.
