Buying Guide: Key Purchase Considerations
- Viewer angle and door thickness: For broad visibility, choose higher-height knocker models with wide-angle peepholes and compatibility with your door thickness (commonly 1-3/8″ to 2-1/4″ or 1.4″ to 2.1″).
- Material and finish: Zinc die-cast is common for durability; brass offers corrosion resistance and a classic look. Matte black finishes work well with modern door hardware.
- Hole integration: Most options require a 1/2″ to 9/16″ bore for peepholes. Confirm hole size and placement on your door before ordering.
- Size considerations: Larger knockers (like 6″ or 7-3/8″) provide a bold aesthetic but may require more mounting space and door strength.
- Security vs. decor: Some models emphasize privacy and security viewing; others accent traditional door design. Match your priority to the product.
- Installation ease: Look for kits that specify simple mounting guidelines and included hardware for common door materials.
