Buying Guide: Square Glass Door Knobs
- Privacy vs. passage: Choose privacy knobs with locking mechanisms for bedrooms and bathrooms, and passage knobs for closets, halls, or pantry doors.
- Finish and style: Matte black, satin brass, antique brass, and black crystal finishes coordinate with common interior themes. Match with existing hardware to maintain consistency.
- Door compatibility: Check door thickness (commonly 1-3/8″ to 1-3/4″) and backset (2-3/8″ or 2-3/4″). Ensure latch type and strike plate align with your door frame.
- Emergency features: Some privacy knobs include an external emergency release. Confirm the release method and tool included, especially for hard-to-reach doors.
- Installation complexity: Most sets are DIY-friendly, but verify the included template, screws length, and tool requirements before purchasing.
