This UL-listed model is part of our Builders Hardware door knockers and viewers range.Practical Uses Solid entry doors: Add a viewing point where door construction and preparation are suitable. Replacement projects: Replace a compatible door viewer after confirming the existing opening and door thickness against the 10ULDV202 drawing. Entry observation: Look outside from inside without first opening the door. Everyday example: When a visitor knocks, an occupant looks through the 10ULDV202 before deciding whether to open the door, keeping the door closed during the visual check.ApplicationDesigned for doors 19/32 to 1 inch thick, including compatible thin-panel doors. Suitable for residential, commercial, and multi-unit applications.Fit and Preparation Bore-hole diameter: 9/16 inch Door-thickness range: 19/32 to 1 inch Check the drawing: Compare the dimensions in the linked 10ULDV202 cut sheet with the actual viewer, door thickness, and existing preparation before ordering or drilling. Do not assume another viewer model uses the same opening.Installation GuidanceChoose a practical height: Position the viewer for the intended occupants and check both door faces for panels, glazing, nearby hardware, and internal components that could interfere.Confirm compatibility: Verify the required preparation against the actual part and manufacturer information before making an opening. For a labeled door assembly, confirm the permitted hardware and preparation with the door manufacturer before modifying the door.Install and check: Follow the manufacturer's installation guidance for orientation and assembly. Protect the door finish and optical surfaces, then confirm a clear view from inside. The viewer is an observation accessory, not a lock or substitute for securing the door.Problems It Helps Address Thin-panel door applications: Can be used for thin-panel doors. Confirm the actual panel thickness and preparation against the 10ULDV202 drawing before installation. No view through a solid door: Adds a viewing point when installed in a compatible door.
