Quick Summary
The best panic bar for glass storefront doors is a rim exit device matched to your stile width and door preparation. For most single-door storefronts, the A9800 and AF9800 series is the strongest all-around choice, while the 5000 series fits tighter stiles with its 3-3/4" minimum.
- Rim devices suit glass storefronts because no rod runs down the visible glass face.
- The A9800 and A7700 series require a 4-1/2" minimum stile with standard strike and trim.
- Fire-rated models use a steel chassis and include thru-bolts as standard.
- Dogging is standard on non-fire-labeled devices only, never on fire exit devices.
- Confirm stile width, door thickness, and 2-3/4" backset against the template before drilling.

What Makes a Rim Exit Device for Storefront Door Openings Work
A rim exit device for a storefront door is a touch-bar assembly that mounts to the face of the door and latches into a strike fixed to the frame. The bar travels in the direction of the door swing, releasing a stainless steel latch bolt with a 3/4" throw.
Most guides get the compatibility question backwards. They start with the device and work outward. We start with the door, because the stile width and preparation decide everything else.
Stile Width, Backset, and Door Preparation
Stile width is the flat vertical edge of the door where the device mounts. On an aluminum-framed storefront door, that stile is often narrow, and a device that needs more room simply will not fit.
Backset on these series is 2-3/4", and standard door thickness is 1-3/4", with 2-1/4" listed as optional. Confirm all three figures against the manufacturer's template for your exact model before anyone drills. A common mistake is ordering by door width alone and assuming the preparation will line up.
Fire-Rated vs. Non-Fire-Rated Devices
Fire-rated and non-fire-rated devices are not interchangeable, and the difference is not cosmetic. On our lines, the panic configuration carries a non-ferrous alloy chassis while the fire exit configuration uses a steel chassis, and thru-bolts come standard on fire-rated models. Allen-key dogging is standard on non-fire-labeled devices only, so you cannot dog a fire exit device shut.
If the opening carries a fire label, specify the fire exit model and follow its listing. Installing a panic device on a labeled door does not preserve the rating of the opening.
1. A9820EO 48" ADA Exit Device: Best for Wide, Accessible Openings
Start here if accessibility is the deciding factor.
What most specifiers miss is that ADA compliance is a property of the complete installed opening, not the box. The device supports accessibility; the door, closer, and threshold have to cooperate.
View the A9820EO 48" ADA exit device for the full specification and current availability.
Best for: wide storefront entrances and any opening where accessible egress is a stated requirement. Skip if: your stile is narrow or your door width will not carry a 48" bar.
2. A9800 & AF9800 Series: Best All-Around Rim Exit Device for Storefront Doors
The A9800 and AF9800 series is the pick we recommend most often for glass storefront doors, and it earns that spot on flexibility rather than flash.
The details that matter in practice: ANSI A156.3 Grade 1 construction, a stainless steel latch bolt with 3/4" throw, a 239 strike packed standard, and a cover described as fitting stock hollow metal doors with a 161 cutout. The series also identifies retrofit applications for Sargent 8800 Series when using 9800 escutcheon trim. Treat that as a starting point for comparison, not a fit guarantee.
The one drawback is that outside trim is not included with every selection, so confirm package contents before you order.
See the A9800 and AF9800 rim exit device for lengths, finishes, and ordering details.
Best for: most single-door storefront openings and properly configured pairs. Skip if: you need the tightest stile clearance, in which case look at the 5000 series.
3. A7700 & AF7700 Series: Best for Heavy Traffic and Finish Matching
When the entrance takes a beating and the hardware is visible from the sales floor, the A7700 and AF7700 series is the upgrade.
In practice, the anti-pick latch matters less than strike alignment.
The 7700 series identifies retrofit applications for Von Duprin 99 and 98 Series when using 7700 escutcheon trim. Compare the existing preparation, strike, and mounting locations first.
Review the A7700 and AF7700 rim exit device for finish options and specifications.
Best for: high-traffic entrances where finish coordination is part of the design brief. Skip if: budget is the primary constraint.
4. A6600, A2200, and 5000 Series: Budget and Mid-Range Picks
Three series cover the value end of the range, and they are not simply cheaper versions of the same thing.
The A6600 Series at $177.00 gives you a steel chassis, heavy-gauge rail assembly, and an anti-pick stainless steel latch bolt in US32D or Alum.
The A2200 and AF2200 Series at $133.00 offers 24", 36", and 48" EO sizes, five finishes, and a 239 strike. It identifies retrofit applications for Sargent 12-2828 and 12-2838 Series.
The 5000 and F5000 Series at $118.00 is the one to reach for when the stile is the problem.
Watch out: a lower price often reflects a narrower range of included accessories, not lower build quality. Confirm what ships in the box, especially outside trim.
5. 9800 Alarm Panic: Best When You Need Exit Alarming
The 9800 Alarm Panic at $649.80 is the choice when the door needs to announce its own use.
Here is the part most listings gloss over. The alarm is described as available, and the exact supplied alarm kit, activation and reset method, and power requirements should be confirmed before ordering.
Test the mechanical device and the alarm separately after installation. If the door stops relatching, the fix is usually in the opening alignment, not the alarm.
Check the 9800 Alarm Panic for lengths, finishes, and configuration details.
Choosing a Narrow Stile Exit Device for Frameless and All-Glass Doors
A narrow stile exit device is a rim device sized to mount on the slim vertical edge of an aluminum or all-glass door, where a standard-width device will not fit. On frameless glass, the mounting surface is minimal, so the stile width figure is the first number you check, not the last.
Work through this checklist before you order:
- Measure the actual stile width on the hinge and latch edges
- Confirm door thickness, typically 1-3/4" with 2-1/4" optional
- Verify the 2-3/4" backset against the existing preparation
- Confirm the strike position and whether the frame can carry it
- Check whether the opening carries a fire label
- Confirm outside trim is included if you need access control
- Pull the model-specific preparation template before drilling
For a glass storefront door, a rim panic device is almost always the right family. The vertical rod alternative adds hardware down the face of the door, which fights the clean architectural appearance that glass entrances exist to deliver.
Storefront Door Exit Device Installation: Steps and Common Mistakes
Storefront door exit device installation follows a fixed sequence: verify the opening, mark from the template, drill, mount the device and strike, then test through repeated cycles. Skipping the verification step is where most jobs go wrong.
- Confirm the model against the door. Match stile width, thickness, backset, and handing before unpacking hardware.
- Pull the correct template. Use the template for your exact model. A shared instruction document does not make panic and fire models interchangeable.
- Mark and drill. Check mounting clearance and door condition before the bit touches metal.
- Mount the device and strike. Thru-bolts are standard on fire-rated models and available on request for others.
- Test the cycle. Operate the touch bar, check latch engagement, then close and latch the door repeatedly.
The most common mistake we see is diagnosing a stiff bar when the real problem is a misaligned strike or a door that no longer sits square in the frame. Check the complete opening before replacing hardware.
For reference on the standards behind these devices, the ANSI/BHMA A156.3 standard for exit devices defines the Grade 1 performance levels these series are built to, and UL 305 covers panic hardware fire listings. Your local authority having jurisdiction has the final say on egress requirements for a given occupancy, so confirm the assembly against the applicable code before installation.
Frequently Asked Questions
Can you install a panic bar on a glass storefront door?
Yes, provided the door has a wide enough metal stile to mount the device. A rim panic bar for glass storefront doors fastens through the vertical stile and the frame-mounted strike, not through the glass itself. Cal-Royal rim devices list a 4-1/2 inch minimum stile width with standard strike and trim, and the 5000 Series lists 3-3/4 inches. Measure your stile, confirm door thickness at 1-3/4 inches, and check the 2-3/4 inch backset before ordering.
What type of panic bar works best on an aluminum storefront door?
A rim exit device is the usual choice for a single aluminum-framed storefront door. It mounts on the face of the door with a strike on the frame, so it suits narrow-profile stiles better than a surface vertical rod device, which needs rods running to the floor and header. Match the device to the opening: a non-fire-rated panic device for standard exits, or a fire-rated model such as the AF9800 when the door carries a fire label.
What is the difference between a rim exit device and a vertical-rod exit device?
A rim exit device latches at a single point, using a latch bolt that engages a strike mounted on the frame. A vertical-rod device adds rods that extend to the header and floor for latching at two or three points, which suits wider or taller openings and pairs of doors. For a typical single glass storefront door, a rim device keeps the hardware off the glass and the frame cleaner. Vertical rods make more sense on double doors where both leaves need secure latching.
Can you retrofit a panic bar onto an existing storefront door?
Often yes, but preparation decides it. A panic bar retrofit for aluminum door frames depends on whether the existing holes, strike position, and stile width match the new device's template. Cal-Royal lists some retrofit applications, such as the A9800 for Sargent 8800 Series with 9800 escutcheon trim, but the listing is a starting point, not a fit guarantee. Compare the existing strike, mounting locations, and trim before drilling, and expect to fill and redrill holes if the patterns differ.
Who should install an exit device on a glass storefront door?
A locksmith or commercial door contractor is the safer choice when the door is fire-rated, when the stile is narrow, or when the existing preparation does not match the new device. The work involves drilling aluminum stiles, aligning the strike, and confirming the door latches through repeated cycles. A DIY installation is realistic on a standard hollow metal or aluminum door if you use the manufacturer's template and follow the model-specific instructions, but a fire-labeled opening should be signed off against its listing.
Matching a panic bar to a glass storefront door is a measurement problem before it is a product problem, and getting the stile width, backset, and fire rating right the first time saves a return and a re-drill. At Cal Royal Hardware, we stock Grade 1 exit devices across six series with fast distribution, heavy-duty construction, and finish options that hold up on a visible storefront. Search our store to compare rim exit devices and find the model that fits your opening.
