The MaxxGeek flat slot storm door handle set provides a complete upgrade for screen and storm doors. It features a mortise lock body with a keyed deadbolt and includes two keys for reliable access control. The design supports both left- and right-handed installations and suits door thicknesses from 1.125 to 2 inches, making it a versatile choice for many homes. The included installation kit simplifies the upgrade, ensuring you have the necessary hardware and instructions to complete the job without extra parts.
MaxxGeek 2 Point Bolt Mortise Lock Body For Pella
This replacement mortise lock body is designed for Pella storm doors, delivering a 2-point locking mechanism for enhanced security. The bolts are spaced 2-1/2 inches apart, with an overall faceplate length of 8-1/2 inches. The product coordinates with compatible screws and typical Pella assemblies, and it uses a hand-actuated control to operate the lock. Consider this option when refreshing a worn or damaged lock body without replacing the entire door hardware.
MaxxGeek Flat Slot Storm Door Handle (Matte Black)
The matte black variant of the MaxxGeek flat slot line matches the brushed nickel option in form, while offering the same wide compatibility and keyed deadbolt for security. The complete kit includes lever handles, a mortise lock body, and the two supplied keys, along with clear instructions for installation. This version suits homes seeking a darker finish to coordinate with exterior hardware and paint schemes, without sacrificing reliability or ease of use.
Storm Door 2 Piont Mortise Lock Body Replacement (White)
Designed for Pella storm doors, this replacement mortise lock body provides a 2-point locking mechanism with a centered deadlock and a 2-1/2″ bolt spacing. It is not universal, so verify compatibility with your existing hardware before purchasing. The assembly is compatible with replacement cylinders made by Pella, and the lock knob rotates 270 degrees before the cam engages, ensuring secure operation when locking or unlocking.
Turstand Flat Slot Storm Door Mortise Lock Body
Turstand offers a flat slot mortise lock body that fits older storm doors with 4-sided spindle hubs. It comes with a 2-1/2″ handle PZ and a 7/8″ backset. A key consideration is spindle hub compatibility; Turstand warns that it may not fit doors with different spindle shapes, such as Larson QuickFit variants. When compatible, the unit provides a precise, straightforward replacement without needing a full handle upgrade.
Offset Euro Profile Lock Cylinder With Thumb Turn
This cylinder with thumb turn is designed as an OEM replacement for Pella’s 2-Bolt mortise locks on storm doors. It includes three solid brass keys and provides a straightforward upgrade path for existing cylinders. The 270-degree key turn before the cam engages adds a reliable security step, making it a practical choice for homeowners seeking to refresh a single component rather than the entire lock system.
2 Point Bolt Mortise Lock Body For Pella (White)
This 2-point bolt mortise lock body is a suitable replacement for Pella storm doors, offering a solid improvement over worn hardware. It is designed to be used with compatible Pella lock cylinders and handlesets. The product notes emphasize the need to match spacing and handle-to-cylinder dimensions, ensuring the installation aligns with predrilled holes and the door’s edge mortise.
Ideal Security GLK Deadbolt For Storm Doors
The Ideal Security GLK deadbolt kit provides an elegant keyed deadbolt option for storm and screen doors. This 2-piece set adds an extra layer of exterior security, suitable for doors where a deadbolt entry is desired. It’s lightweight and straightforward to install, with emphasis on reliable key-operated locking performance in exterior environments.
Buying Guide: Key Considerations When Choosing a Storm Door Lock Mechanism
- Door compatibility: Measure hinge side, thickness, spindle type, and PZ spacing to ensure the lock aligns with your door’s existing mortise and handle geometry.
- Locking mechanism type: Decide between deadbolt, 2-point bolts, or a combination. 2-point locks often offer greater resistance to twisting and forced entry compared to single-point systems.
- Material and finish: Match hardware finishes with exterior fixtures (brushed nickel, matte black, white) for aesthetic consistency and corrosion resistance in harsher climates.
- Installation scope: Some options are full handle-set replacements with mortise bodies; others are replacement lock bodies only. Consider whether you need a full kit or a partial upgrade.
- Security vs. convenience: Keyed deadbolts add security but require carrying keys. Some systems include emergency release options or simple thumb-turn cylinders for quick access.
- Compatibility notes: Many products are designed for Pella doors or specific spindle hubs. Always verify that the model matches your door’s spindle, faceplate, and hole spacing before purchase.
- Maintenance and warranty: Look for corrosion-resistant finishes and manufacturer warranties. Regular inspection can prevent wear from exposure to sun, rain, and humidity.
- Product support: Consider whether the seller provides clear installation instructions, included hardware, and replacement parts availability for future repairs.
