Satco-nuvo 90480 Keyless Ceiling Lampholder 660W 250V

Product Description

The SATCO-NUVO 90480 is a keyless ceiling lampholder designed for medium-base lamp installations in residential and light commercial settings. Built from white phenolic, this receptacle connects via four screw terminals and accommodates loads up to 660 watts at 250 volts. The 4.5-inch diameter housing mounts flush to a ceiling outlet box, providing a clean, low-profile finish. Double set screws secure the lamp base firmly in place, reducing vibration-related loosening over time. Electricians and maintenance technicians install this type of fixture base in utility spaces, closets, storage areas, and anywhere a simple keyless lampholder is the right tool for the job.

The 90480 is suited for new construction and retrofit applications where a straightforward, no-switch ceiling receptacle is required. Its white phenolic construction handles moderate heat loads typical of incandescent and compatible medium-base lamps. The four-terminal screw connection supports standard branch-circuit wiring and allows reliable conductor termination without pigtailing. It is commonly installed in basements, attics, garages, and utility rooms where a decorative fixture is not needed.
