The 1591HC is a clear polycarbonate lid made to fit 1591H enclosures in the 1591 Series of ABS plastic multipurpose enclosures with card guides. It lets designers and technicians see displays, LEDs or the circuit board inside without opening the box.

The lid measures 6.52 x 2.79 x 0.24 in (166 x 71 x 6 mm) and is molded from clear polycarbonate with a UL94 V-0 flame rating. The part page lists an IP54 rating, and the lid is RoHS and REACH compliant. Some chemicals can damage polycarbonate, so avoid acetone, ketones, strong solvents and thread locking compounds.

In the series ordering tables the 1591HC is the clear lid accessory for every 1591H enclosure, which measures 6.54 x 2.80 x 1.14 in (166 x 71 x 29 mm):

• Without flanges: 1591HBK, 1591HGY, 1591HSBK, 1591HSGY
• Flanged lid: 1591HFLBK, 1591HFLGY, 1591HSFLBK
• Bottom flange: 1591HF2BK, 1591HF2GY, 1591HF2SBK, 1591HF2SGY

The 1591HC is supplied as a lid only, in shrink wrap, with a shipping weight of 0.08 lbs (0.04 kg). Its UNSPSC code is 39121301. Because the same lid is listed across flame retardant and general purpose, flanged and unflanged versions of the 1591H, one part number covers every enclosure of this size in the 1591 Series.
