Adapter Plate for One- and Two-Gang Boxes

This ivory adapter plate fits standard one- and two-gang device boxes and provides two gangs of mounting space. It is constructed from polycarbonate and carries CSA certification and US listing for dry indoor locations. The hospital-grade rating indicates durability suited to demanding commercial environments. Overall depth and width are both 4.78 in with a height of 0.58 in.

Suited for Commercial and Healthcare Installations

Electricians and facility managers adding or rearranging outlets in hospitals, clinics or offices will find the hospital-grade construction and dual-gang format convenient. It is not intended for outdoor or damp locations, nor for single-gang boxes that cannot accommodate the 4.78 in width. Builders needing weather-resistant plates or extra gangs should look elsewhere.

Behaviour Under Continuous Use

The polycarbonate body resists impact and heat generated by devices mounted in the plate during sustained operation. CSA and US listings confirm the materials meet safety requirements for continuous indoor service. No moving parts or active components are present, so long-term reliability depends on proper installation in a compatible box.
