The RP1450 is a low profile polycarbonate enclosure with an opaque lid, measuring 220 x 165 x 60 mm (8.66 x 6.50 x 2.36 in). The wide, shallow footprint suits a single large circuit board or a row of DIN rail devices, making it a practical choice for electronics designers, control builders and installers.

Polycarbonate gives this model a UL94 V-2 flame rating, versus UL94 HB for the ABS equivalents. The lid seals with a two piece tongue & groove joint and a field-installed EPDM string gasket to an IP65 rating, and four self captivating M3.5 stainless steel screws secure it into corrosion resistant bushings. The part page lists the colour as Light Gray, while the series ordering table places it in the Off-White Polycarbonate column.

Inside the RP1450 the drawing shows 211.37 x 156.37 x 53.50 mm (8.32 x 6.16 x 2.11 in) of space. P.C. boards up to 205 x 150 mm mount on posts that accept M3 self-tapping screws, and the lid top has a recessed inlay 0.40 mm deep for a label, overlay or silkscreen.

Each unit ships in a bag with box, lid, string gasket, four PCB screws and four lid screws, at a shipping weight of 1.11 lbs (0.50 kg). It is RoHS and REACH compliant. For this size the ordering table lists inner panels STC146 and STA146, replacement gasket RP145GASKET, and open "U" slot mounting feet kits MF0050 and MF0055.
