It’s a hardware-only fix for matching doors, so the key to a smooth install is confirming your spindle shape and mortised opening before ordering.

Pros:
- Designed as a replacement body for doors using a 4-sided spindle hub.
- Includes a 7-inch faceplate hole spacing with screws included.
- Non-handed design works for either door orientation.
- Requires a factory bored 5/8-inch by 5-3/4-inch mortised hole, which matches its intended use.
Cons:
- Not universal and not compatible with Larson QuickFit 5-sided or hex spindle hubs.
- Lock body only, so you’ll need compatible existing handle components.
- Fit depends on matching the spindle hub shape and key cylinder style.

Lock Body Replacement – Reversible Storm Door Lock Body
For shoppers focused on storm door mortise locks, this replacement body is the simpler option when the handles and cylinder are still usable. It is made for certain old storm door setups, uses a 2-1/2″ handle PZ, and includes a reversible latch bolt for outward-opening doors.

If you want storm door mortise locks with a more traditional look, this brass handle set is built as a keyed replacement for certain storm and screen doors. It supports 22mm and 26mm backset options, has a reversible latch, and includes the lock body, keyed cylinder, keys, handles, spindle, strike plates, and mounting hardware.

- Requires careful test-fitting of handle movement, key rotation, latch, and deadbolt before final tightening.
This is the most complete keyed option in the group and is well suited to a full replacement on a compatible door. Its main strength is adjustability, but that same flexibility still depends on matching your door’s measurements.
How We Picked These Storm Door Mortise Locks
We prioritized fit and replacement compatibility over cosmetic extras. That means checking handle center-to-center spacing, backset dimensions, spindle style, latch direction, and whether the lock is meant for older storm doors, Pella-style doors, Larson/Wright-style hardware, or keyed handle sets with deadbolts.
We also favored options that cover the most common real-world needs: full handle sets for a complete refresh, and lock bodies for homeowners who only need to replace the internal mortise mechanism.
Quick Comparison: What to Match Before You Buy
Most problems with Storm Door Mortise Locks come from mismatched measurements. Before ordering, confirm the handle PZ, backset, spindle hub shape, door thickness range, and whether your existing setup uses a flat slot, offset Euro, or 2-point bolt design. If your current hardware is branded, matching the brand pattern can save a lot of trial and error.
Key Buying Factors for Storm Door Mortise Locks
Fit and Measurements
Backset and handle spacing are the biggest compatibility checks. Even small differences can prevent the lock body from seating correctly or the handles from lining up.
Complete Set Vs. Lock Body Only
If the exterior and interior trim still work, a lock body replacement may be enough. If the handle, key cylinder, or deadbolt is worn or corroded, a complete set is usually the better value.
Latch Style and Reversibility
Many Storm Door Mortise Locks use reversible latch bolts, which makes installation easier on left- or right-hinged doors. This is especially helpful for older doors with less-standard configurations.
Security and Convenience
Keyed lever mounts and deadbolts add security, while simpler latch-only designs are often sufficient for basic screen-door use. Choose the level of security that matches the door’s location and daily use.
Finish and Durability
Finish matters if the door sees sun, moisture, or frequent touching. Brass, polished nickel, and matte black are common choices, but the best finish is one that resists wear and matches existing hardware.
Who Should Buy Which Storm Door Mortise Locks?
If you are replacing an aging mechanism on an older door, a lock body-only option is often the most practical pick. If you want a cleaner upgrade with better security, choose a complete keyed set with a deadbolt. For brand-specific replacements, match the hardware family first, especially with Pella, Larson, and Wright-style doors. Homeowners who want the simplest route should focus on Storm Door Mortise Locks with clearly listed backset, PZ, and door-fit specifications.
