Larson Storm Door M2 Mortise Brushed Nickel Handle Set - Keyed

In this review we look at the Larson Certified Storm Door M2 Mortise Brushed Nickel Handle Set and why it is a sensible replacement for owners of Larson storm doors. The bottom line: if you have a Larson storm door with the factory mortised edge hole, this handle set swaps in quickly, matches interior and exterior aesthetics, and restores keyed security without fuss. Installation is straightforward enough for a homeowner with basic tools, and the rotating lever offers a familiar, usable grip that looks more refined than many stock handles.

Key Features

• Intended fit: Designed specifically for Larson doors, it drops into place when your door has the factory mortised edge hole for a direct replacement.
• Mortise compatibility: Works with doors that have a factory bored 9/16-in by 1-3/8-in mortised hole, avoiding extra cutting or modification.
• Rotating lever: The classic rotating lever provides an ergonomic grip for easy operation, useful for frequent entry and exit.
• Keyed deadbolt: Matching interior and exterior levers include a built-in keyed lock to restore security to a storm door.
• Complete hardware: All mounting hardware and instructions are included so replacement can be completed without sourcing extra parts.

Who It's For

This handle set is best for homeowners or maintenance staff who already own a Larson storm door and need a like-for-like replacement that preserves the door's appearance and locking function. It is especially useful when the existing handle is worn or the keyed lock no longer operates reliably.

It is not intended for non-Larson doors or doors without the specific factory mortised edge hole; buyers with nonstandard hardware, custom doors, or those seeking a different finish or keyed system should look elsewhere.

Pros & Cons
