Product Description

The DELTANA 55211CR003-UL is a fire rated door viewer designed for installation in fire-rated door assemblies where code-compliant vision panels are required. This viewer is finished in Lifetime Brass, a durable coating suited for high-use commercial and residential applications. At 0.05 pounds and compact in size, it installs cleanly into standard door bore preparations. Licensed door hardware specialists and commercial contractors typically specify this viewer on projects where UL listing is a code requirement for the door assembly.

This door viewer is appropriate for use in commercial buildings, multi-family residential projects, hotels, and institutional facilities where fire-rated hardware must meet specific listing requirements. It is sold individually and is suited for new construction as well as fire door upgrade and compliance work on existing openings.

Compatibility

Installation Notes

Installation of fire-rated door viewers must comply with the door assembly listing requirements and applicable local building codes, including NFPA 80 standards for fire doors. A licensed door hardware installer or qualified contractor should verify that the door assembly rating is maintained after installation. Ensure the door is properly supported and that the existing bore diameter matches the viewer specification before installation. Do not modify the door or viewer in any way that would void the UL listing.
