What This Guide Covers and Who It Is For
Aluminum storefront doors are the most common commercial entrance type in retail, office, and mixed-use buildings -- and they account for a significant share of all access-controlled openings specified each year. Yet storefront hardware is frequently misunderstood at the point of selection: the frame profile is thinner than hollow metal, the hardware pockets are narrower, and the egress and access-control options work differently than on a standard wood or steel door. This guide walks contractors, facility managers, and specifiers through the key hardware categories, what each one does, and what to get right before ordering.
What Is Aluminum Storefront Hardware?
Aluminum storefront hardware refers to the complete set of door hardware components -- locks, exit devices, closers, pulls, strikes, and seals -- designed to work within or on the narrow aluminum stiles and rails of a commercial storefront door system. Because storefront aluminum is extruded to specific profile dimensions, hardware must be engineered to fit those profiles. Standard hollow-metal hardware rarely drops straight in without modification or a different product family entirely.
The Lock: Mortise Latch, Deadbolt, or Both
The locking function on an aluminum storefront door is almost always handled by a narrow-stile mortise lock mounted in the door's vertical stile. Unlike a standard commercial mortise lock body, storefront mortise locks are slimmer to fit the limited stile depth.
- Latch bolt (3/4 inch throw): The most common configuration. The latch retracts when a lever or paddle handle is operated. A deadlatch feature prevents the bolt from being shimmed back.
- Deadbolt: Added when after-hours security requires a bolt that cannot be retracted without a key or thumb turn. Common in retail tenant spaces.
- Combination units: Latch and deadbolt in a single mortise body -- useful when the stile is wide enough to accept both.
For keyed entry on storefront doors, cylinders must be sized and profiled for the specific lock body. Many storefront mortise locks use a specific cam or tailpiece that does not accept a standard commercial cylinder without an adapter. Verify compatibility before ordering replacements.
Exit Devices on Storefront: Pullman Latches and Panic Bars
When occupant load triggers an exit device requirement -- typically 50 or more occupants in an assembly or mercantile space -- the storefront door needs listed panic hardware. Two configurations are common:
- Pullman-style latch (star wheel): A slim cross-bar or paddle that retracts the latch bolt. Used in many retail and office applications where a full rim panic device is not required or where the designer wants a lower-profile look.
- Rim exit device (narrow stile): A full panic bar spanning the door width, listed for panic and sometimes for fire exit use. Brands such as Sargent, Corbin Russwin, and Hager offer narrow-stile rim exit devices engineered for aluminum storefront profiles.
Always confirm whether the opening requires panic hardware (ANSI/BHMA listed for panic) versus a simple exit device. The AHJ and applicable building code determine the threshold. NFPA 101 and the IBC both address egress hardware requirements based on occupancy and occupant load.
Electric Strikes: The Most Common Access-Control Solution for Storefront
Because aluminum storefront doors see heavy access-control use in retail, professional office, and mixed-occupancy buildings, electric strikes are the dominant electrified hardware solution at these openings. The electric strike replaces the fixed keeper in the frame, allowing the latch bolt to be released electrically while the mechanical lock remains intact.
What to Know Before Specifying an Electric Strike on Storefront
- The strike must be matched to the specific latch bolt profile -- storefront latch bolts vary in size and keeper depth.
- Fail-safe (power to lock) versus fail-secure (power to unlock) must align with the egress and security requirements of the occupancy.
- When the door is also serving as an egress door, the code path for electromagnetically locked or electrically controlled egress doors applies. IBC and NFPA 101 both require that operation of the door hardware directly interrupts power to the lock and that loss of power unlocks the door (fail-safe requirement for many egress applications).
- Frame depth in aluminum storefront is limited. Verify the strike body dimensions fit the frame section before ordering.
DoorwaysPlus carries electric strikes from multiple lines suited to storefront applications. Contact our team to confirm the right unit for your latch bolt and frame profile.
Door Closers on Storefront Aluminum
Surface-mounted door closers on storefront doors must be sized carefully. Storefront aluminum frames and door stiles have limited reinforcement compared to hollow metal, which means bracket mounting and screw pull-out strength are real concerns on high-cycle retail entrances.
- Parallel arm mounting keeps the closer body on the push side -- preferred for exterior storefront doors to protect the closer from weather and vandalism.
- ANSI closer sizes 1 through 4 cover most storefront door weights and widths. Oversizing creates excessive closing force that may violate ADA opening force requirements (5 lbs. on interior doors).
- For retail and restaurant storefronts with high daily traffic, specify a closer rated for heavy-duty cycles. Brands such as Norton, Hager, and PDQ offer commercial closers with consistent cycle ratings for high-use entrances.
Pull Handles, Push Bars, and Trim
On an all-glass or storefront aluminum door, pull handles do a lot of work aesthetically and functionally. Back-to-back pull sets are the standard configuration. Key considerations:
- Handle diameter, projection, and center-to-center spacing must match the door rail height and glass thickness.
- ADA requires hardware operable with one hand without tight grasping, pinching, or twisting. Lever-style and D-pull handles typically satisfy this requirement; round knobs do not.
- Where an electric strike with built-in switch is specified, the pull handle must be the listed hardware with the integrated switch that directly interrupts lock power -- not a generic pull added after the fact.
- Push bars (flat bar push plates) on the egress side are common on single-action storefront doors where a panic device is not required. Rockwood and Pemko offer push bar and pull handle trim lines suited to aluminum door profiles.
Weatherstripping and Thresholds: Sealing the Storefront Opening
Retail storefront doors take a beating at the perimeter seal. Pile weatherstrip in the door frame channels and door stop, combined with a low-profile threshold at the sill, handles the weather load while meeting ADA threshold height limits (1/2 inch maximum; 1/4 inch for abrupt vertical rise).
- Storefront pile weatherstrip is sized to the specific frame pocket -- universal roll-in pile is available for many common pocket profiles.
- Thresholds for storefront applications must clear the bottom rail and allow the door to swing freely. Pemko manufactures threshold and door bottom combinations engineered for aluminum storefront sill conditions.
- Door bottoms and sweeps on storefront doors must not create drag that exceeds ADA opening force limits or prevents the closer from latching the door reliably.
Putting the Full Opening Together
A complete aluminum storefront hardware package typically includes: mortise lock body, trim (lever or pull), cylinder, electric strike or fixed keeper, door closer with appropriate arm, pull handles or push bar, weatherstrip, threshold, and door bottom. Each component must be compatible with the others and with the specific frame extrusion profile on the job.
Getting one piece wrong -- an electric strike with the wrong keeper depth, a closer arm that does not clear the top rail, a threshold that binds the door -- means a callback. DoorwaysPlus stocks and sources the full range of storefront hardware categories and can help you build a coordinated opening package before the door goes in.
