Buying Guide: Key Considerations When Choosing A Mortise Storm Door Handle
Do you need a mortise or a cylindrical/lever set?
Mortise sets integrate the latch within a mortised cavity in the door edge, often offering higher security. Cylindrical or lever-only options may be easier to install but can be less secure. Choose mortise if your door supports it and you want stronger hardware for exterior use.
Door thickness and bore compatibility
Most mortise sets specify a door thickness range and bore dimensions. Measure door edge bore size, thickness, and backset before ordering. Mismatched dimensions can lead to misalignment or a non-functional latch.
Left-handed vs right-handed doors
Some mortise sets are non-handed, while others are clearly left- or right-handed. Reversible designs can simplify installation on either door orientation. When in doubt, select a reversible model.
Backset and alignment
The backset is the distance from the door edge to the center of the bore hole. A standard backset is common, but some doors require 3/4″ or other backset measurements. Ensure the backset matches your door for smooth operation.
Material and finish
Look for zinc alloy or steel with corrosion-resistant finishes such as brushed nickel or polished nickel. Exterior doors encounter weather exposure; finishes should resist rust and wear over time.
Security considerations
A keyed deadbolt adds security beyond the lever latch. Ensure the set includes a deadbolt and that keys are provided for convenient access. Consider whether your door’s strike plate and frame can handle the added reinforcement.
Installation kit and compatibility
Some sets come with full installation kits, including warrants, screws, and alignment guides. A complete kit reduces the need for additional purchases and simplifies replacement on older doors.
Maintenance and care
Regularly lubricate moving parts with a light graphite or silicone lubricant. Wipe exterior hardware to remove dirt and moisture. Proper maintenance extends the life of the mortise mechanism.
Frequently Asked Questions
- What is a mortise storm door handle? A mortise storm door handle uses a lockset integrated into a mortised cavity in the door edge, offering enhanced security and a robust latch mechanism for exterior doors.
- Do I need to replace the entire door to change the handle? Not usually. Many mortise sets are designed to replace existing hardware on compatible doors without full door replacement, provided bore and backset match.
- How do I know which backset my door needs? Measure the distance from the edge of the door to the center of the bore hole. This measurement determines the backset, typically 3/4″ or 1-1/8″.
- Are reversible mortise handles easier to install? Yes, reversible designs let you use the same handle on both left- and right-handed doors, simplifying installation.
- Is a deadbolt essential for security? A keyed deadbolt adds an extra security layer beyond the latch, which is recommended for exterior storm doors in most cases.
- What finishes resist weather best? Finishes like brushed nickel and polished nickel resist corrosion better in outdoor environments while offering a clean aesthetic.
