Product Description

The DELTANA 55211U26-UL is a fire rated door viewer designed for installation in fire-rated door assemblies where code-compliant vision panels are required. Finished in bright chrome, it provides a clean, professional appearance suited to commercial and residential applications alike.

At 0.05 pounds, the viewer is compact and lightweight, measuring 1.8 inches in length, 1 inch in width, and 1.3 inches in height.

Fire rated door viewers are used in applications where door assemblies must meet fire listing requirements, including corridor doors, stairwell entries, and unit entry doors in multi-family residential and commercial buildings. The UL designation in the part number indicates suitability for use in UL-listed fire door assemblies. This viewer is sold individually and is appropriate for new construction and replacement installations where the existing viewer must meet fire rating standards.

Installation Notes

Installation of fire-rated door viewers must comply with the door assembly manufacturer's listing requirements and applicable local building codes. The door viewer should be installed by a qualified contractor familiar with fire door hardware requirements to ensure the fire rating of the assembly is maintained. Do not modify the bore size beyond the viewer's specified requirements, as alterations may void the fire rating of the door assembly. Verify that the finished door assembly, including the installed viewer, complies with applicable fire door inspection standards before returning the opening to service.
