The DELTANA 55211U19-UL is a fire rated door viewer designed for installation in rated door assemblies where code-compliant vision panels are required. Finished in black, this viewer provides a secure line of sight through fire-rated doors without compromising the door's rating integrity. Weighing 0.05 pounds, it is compact and suited for single-unit installation by carpenters, locksmiths, or finish hardware installers working on commercial or residential fire-door applications.
This door viewer is intended for use in fire-rated door assemblies in commercial and residential construction. It is appropriate for hotel corridors, apartment entry doors, office suites, and any application where a UL-listed vision device is required on a rated door. The black finish suits both modern and traditional door hardware schemes.
Designed as an OEM-style replacement or new-installation door viewer for fire-rated door assemblies requiring a UL-listed viewer unit.
Installation should be performed by a qualified carpenter, locksmith, or hardware installer familiar with fire-rated door assembly requirements. Verify the door's fire rating and local building code requirements before boring the viewer hole to ensure the correct door preparation diameter is used. Do not install in a door or frame that would compromise the door's fire rating. Follow the door manufacturer's instructions and applicable fire door standards for proper viewer placement and boring specifications.
