Buying Guide: Key Purchase Considerations
- Locking mechanism: Decide between mortise locks, keyed exterior pulls, or non-keyed options. Mortise locks provide robust security and compatibility with many door builders, while keyed exterior pulls add external access control.
- Hole spacing and compatibility: Most replacements target 3-15/16” spacing; some models use 6-5/8” spacing. Confirm your door’s hole layout and whether the handle set is reversible for left- or right-handed doors.
- Door thickness and stile width: Check supported door thickness (often 1″ to 1-1/8″ or up to 1-3/4″ for some sets) and stile width to ensure a snug, secure fit.
- Finish and style: White, black, and other finishes affect curb appeal. Consider escutcheon size and whether the design blends with your patio door and home exterior.
- Installation complexity: Most sets are designed for DIY installation—verify included hardware, screw sizes, and whether professional help is needed for mortise work.
- Security considerations: Exterior keying and locking options impact daily use and home security. Choose a configuration that aligns with your door’s security goals.
- Maintenance and durability: Look for corrosion-resistant finishes and hardware rated for frequent use to maximize long-term performance.
Across the options above, homeowners can replace worn handles with locking functionality without a full door replacement. When selecting, match hole spacing, door thickness, and preferred locking style to ensure a secure, aesthetically pleasing result. The combination of durable materials, reversible designs, and easy installation makes these sets strong contenders for upgrading sliding glass doors.
