The light gray RAL 7035 ABS carries a UL94-HB flammability rating. ABS versions are not UL listed but have been tested to and meet IP66, with an IK07 impact rating per IEC 62262:2021 and a recommended operating range of -20°C to +60°C. The gray lid seals with a two-piece tongue and groove joint and a replaceable one-piece silicone gasket, which is supplied loose inside the enclosure.

The drawing lists interior dimensions of 131.32 mm long, 128.38 mm wide and 81.20 mm high, and the part lists a maximum P.C. board size of 127 mm x 127.5 mm. Inside are molded DIN rail tabs, threaded M3 brass inserts, standoffs for #6 self-tapping screws and vertical guides for 1.5 mm boards, while the lid has molded #6 standoffs. A 1554QPL galvanized steel inner panel can be ordered separately.
