Unique-Bargains 200° Brass Door Viewer 16 mm 37–55 mm Polished Chrome

Brass Door Viewer with 200° Coverage

This solid brass door viewer installs in a 16 mm bore and fits doors from 37 mm to 55 mm thick. The polished chrome finish resists corrosion and matches contemporary hardware. A four-element optical lens delivers a 200-degree field of view so occupants can identify visitors before opening the door. The unit includes a privacy cover for times when the peephole is not in use.

Fits Standard Door Preparations

The viewer requires a single 16 mm hole and accommodates door thicknesses between 37 mm and 55 mm without additional spacers. Its 29.5 mm outer flange covers the cutout cleanly on both faces. Total installed length is 48 mm, leaving ample clearance for interior trim or storm doors. No wiring, batteries or network connection are needed for operation.

Optical Performance Over Time

The all-glass lens stack maintains clarity without fogging or yellowing under normal indoor and outdoor temperature cycles. Brass construction resists forced removal better than plastic-bodied alternatives. The wide 200-degree angle remains consistent across the full door-thickness range, eliminating blind spots at the edges. The sliding cover protects the exterior lens from weather and debris when closed.
