The 1455RBBK is a 2-pack of black open bezels made for the Hammond 1455R extruded aluminum enclosure. Open bezels are the plastic frames that sit around the flat aluminum end panels on metal end plate versions of the 1455 series, and the ordering table lists this part under "Open Bezels (For Use w/ Metal End Plate Enclosures)". They suit OEM engineers, electronics builders and repair technicians who need replacement or colour-change trim for an existing 1455R build.

Each bezel is moulded from polycarbonate in black. Black is the colour the enclosures ship with, so this is the like-for-like replacement for a lost, cracked or modified factory bezel. The series literature notes that accessory panels and bezels allow for mixing and matching of colors, and extra plastic bezels are available in black, red, yellow, transparent red and transparent blue.

In the series table the 1455R enclosures measure 165.00 mm wide by 30.50 mm deep and come in 160.00 mm and 220.00 mm lengths. The metal end plate models in that family are 1455R1601, 1455R1601BK, 1455R1601BU, 1455R1601RD, 1455R2201, 1455R2201BK, 1455R2201BU and 1455R2201RD; each of these ships with two open plastic bezels in black as standard.

1455RBBK is the 2-pack: one pair of bezels, which is exactly what one enclosure uses (one at each end). It ships in a bag with a shipping weight of 0.06 lbs (0.03 kg). For production runs or spares stock, the same black bezel is also offered as the 10-pack 1455RBBK-10.

The part is REACH compliant and RoHS compliant.
