Buying Guide: Key Purchase Considerations And Comparisons
- Privacy vs. passage: Choose privacy knobs with a locking mechanism for bedrooms and bathrooms, or passage knobs for hallways and closets that don’t require a lock.
- Finish compatibility: Consider finishes such as brass, antique brass, brushed nickel, bronze, and matte black to align with existing hardware and hardware trends in your home.
- Compatibility with mortise vs. cylindrical locks: Some knobs fit mortise locks, others are designed for standard spindle or universal mortise configurations. Verify spindle size (commonly 6.7mm, sometimes 9/32″) and latch adjustments (2 3/8″ to 2 3/4″) before purchasing.
- Door compatibility: Check door thickness support (typical ranges around 1 3/8″ to 1 3/4″) and latch adjustments to ensure a smooth fit with your interior doors.
- Installation effort: Most sets are DIY-friendly, but mortise lock replacements may require more time and basic carpentry tools. Look for push-button or hex-key release options for emergencies on privacy knobs.
- Aesthetic appeal: Crystal glass knobs deliver a classic, elegant look; fluted glass and rosettes contribute to a vintage vibe, while solid colors like matte black or brushed nickel offer a modern touch.
- Durability and material: Glass knobs paired with zinc alloy or brass bases tend to offer a durable, long-lasting finish. Consider the weight and feel of the knob for daily use.
- Emergency access: Privacy knobs that include an outside release hole or alternative emergency access are essential for bedrooms and bathrooms where needed.
- Replacement fit: If upgrading existing hardware, ensure the new knobs can accommodate the current mortise size and spindle diameter, or plan for sleeve adapters where provided.
