Hubbell HBL4AP Adapter Plate

The Hubbell HBL4AP is a brown polycarbonate adapter plate designed for indoor, dry environments. It fits standard one- and two-gang device boxes and provides a two-gang mounting footprint. The plate carries CSA certification and is US Listed for hospital-grade applications.

Two-gang mounting and polycarbonate build

The plate measures 4.78 inches wide by 4.78 inches deep with an overall height of 0.58 inches. Its polycarbonate construction resists impact and meets hospital-grade durability requirements. The brown finish matches common institutional colour schemes and the flat profile sits close to the wall surface.

Replaces single-gang covers for expanded device

This adapter converts a single-gang opening into a two-gang configuration without cutting new box openings. The upgrade is worthwhile when adding a second switch, receptacle or low-voltage device in an existing location. It is not suited for outdoor or damp locations, nor for installations requiring a deeper device well.
