How We Picked These Double Storefront Door Locks
We focused on compatibility with common commercial aluminum storefront doors, especially models using a 1-1/8" backset and Adams Rite-style components. We also prioritized straightforward replacement options, durable construction, and lock configurations that fit real-world commercial use.
Quick Comparison
Most options in this roundup fall into two main groups: complete mortise lock assemblies and replacement cylinder or thumbturn sets. Complete assemblies make sense when you want a more comprehensive swap, while cylinder-focused options are useful when the lock body is still in good shape.
Key Buying Factors for Double Storefront Door Locks
Backset and Door Prep
Backset is one of the most important details. A 1-1/8" backset is common on storefront hardware, but you should always verify measurements before ordering. A mismatch can cause alignment issues or prevent installation altogether.
Cylinder Type and Keying
Look for whether you need a double cylinder, thumbturn, or keyed-alike setup. Double cylinders provide key access on both sides, while thumbturn configurations can offer easier day-to-day operation in some commercial spaces.
Hook Bolt Vs. Deadbolt Style
Many Double Storefront Door Locks use either a hook bolt or a deadbolt design. Hook bolts can offer strong engagement in aluminum storefront frames, while deadbolt styles may be better for certain existing lock bodies. Match the new hardware to the door’s current strike and mortise cutout whenever possible.
Replacement Compatibility
Some products are direct replacements for specific storefront systems, while others are broader-fit commercial mortise lock parts. If you are replacing worn hardware, compare cylinder length, cam style, and trim dimensions before buying.
Who Should Buy Which Double Storefront Door Locks?
If you need the closest match to existing commercial hardware, choose a direct-replacement mortise lock assembly. If the locking mechanism still works but the keying is worn out, a cylinder or thumbturn set may be the better value. Property managers and business owners handling multiple entries should also consider standardized keying for easier maintenance.
In short, the best Double Storefront Door Locks are the ones that fit your door correctly, match your existing prep, and deliver the level of access control your space actually needs.
