Yes. The entire ROOM Phone Booth and its components are ETL listed and conforms to UL STD 1286. ETL is the official approval mark of Intertek, which is part of a group called Nationally Recognized Testing Laboratory (NRTL) that tests to the UL standards.
UL 1286 is the standard for office furnishings. It’s often used for cubicles and panel systems, as well as certain table and storage products with electrical components. UL 1286 is most representative of ROOM’s Phone Booth because the Booth has an internal wiring and wall structure that most closely resembles a cubicle or panel system in an office space.
