Treasure Coast Locksmith provides Von Duprin service services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Von Duprin is the dominant commercial exit device brand in North America. Main product lines: 98/99 rim devices (most common), SVR/CVR vertical rod devices for pair doors, 33A/35A narrow stile for aluminum storefronts, 22 series lighter duty, and electrified versions for access control.
Von Duprin invented the panic exit device and still dominates the commercial market. The name "Von Duprin" is generic for exit devices in the same way "Kleenex" is generic for tissues. When code requires panic hardware on commercial exit doors, Von Duprin is usually the specified brand.
The product range covers most commercial exit device needs. 98/99 series rim devices are the workhorses - mounted to the door surface with a strike on the jamb, used on single doors and many pair door applications. SVR (surface vertical rod) and CVR (concealed vertical rod) devices use top and bottom latches for pair door applications.
33A/35A narrow stile devices fit the thin stiles of aluminum storefront doors.
Treasure Coast Locksmith services Von Duprin exit devices across all Treasure Coast commercial and institutional buildings. Rebuild with OEM parts, function changes, electric conversion, and full replacement when needed. NFPA 101 compliant and UL-listed fire door service available.

Von Duprin product lines and applications
Von Duprin's product line is extensive. Understanding the main categories helps specify correct service and replacements.
Von Duprin 98/99 Series Rim Devices: The most installed exit device in North America. Mounted on the surface of the door with a strike on the jamb. Used on single doors and many pair door applications.
The 98 and 99 are basically the same device with minor cosmetic differences. Available in multiple trim options, finishes, and electric configurations.
Surface Vertical Rod (SVR): Used on pair doors where latches engage at top and bottom (in the header and threshold) rather than on the active leaf strike. Rods run vertically along the surface of the door face. More complex than rim but necessary for some pair door configurations.
Von Duprin 9827, 9927, and similar model numbers.
Concealed Vertical Rod (CVR): Similar to SVR but rods are concealed inside the door instead of on the surface. Cleaner appearance but requires door construction with internal rod channels. Typically specified for new construction or when aesthetic matters.
Von Duprin 9827L, 9927L, and similar.
33A/35A Narrow Stile: Designed for aluminum storefront doors with narrow stiles (the vertical edges of the door). Standard 98/99 devices don't fit narrow stile doors - too wide. 33A/35A are engineered specifically for storefront applications.
Common in retail, office lobby, and commercial entry applications.
22 Series: Lighter-duty commercial exit device line. Not Grade 1 in all configurations - more like Grade 2. Used for lighter traffic applications where budget matters.
Most serious commercial applications use 98/99 instead.
Electrified Exit Devices: Exit devices with electric operation for access control integration. Electric latch retraction allows the device to be unlocked remotely (via card reader or button) while still providing free egress from inside. Von Duprin 9847EL, 9947EO, and similar electric models.
Common in access control installations.
Alarmed Exit Devices: Include alarm modules that sound if the device is operated during secured hours. Used for anti-theft in retail back doors, emergency exits that shouldn't be routine, and security-monitored emergency doors.
Fire-Rated Models: UL-listed versions of most Von Duprin devices for fire-rated door applications. Specific model suffixes indicate fire rating. Fire-rated devices have internal components preventing dogdown during fire events (unlike standard devices).
Required for labeled fire doors.
Dogdown Feature: Mechanism that holds the latch retracted during business hours, letting the door operate as push-pull without latching. Useful for main entries during open hours. Operated by key or allen wrench.
Fire-rated devices have dogdown disabled or restricted.
Trim Options: Exterior trim for keyed entry with exit device. Lever trim, pull handles, and pull plates with cylinders. Dummy trim has no function except aesthetic appearance.
Trim varies by Von Duprin model and application.
Service Scope: Von Duprin service includes rebuild with OEM parts (latch cartridges, dogdown mechanisms, push rail kits, end caps), function changes, electric conversion of mechanical devices, trim replacement, and full device replacement when repair isn't practical. See Von Duprin for product information.

Service procedures are essentially identical.
Can you rebuild vs replace?
Rebuild in most cases. Von Duprin rebuild kits restore wear items (latch cartridges, dogdown components, springs, end caps) at 30-60% of replacement cost. Replacement warranted for severe damage, very old devices, or multiple simultaneous failures.

Yes. 33A/35A narrow stile exit devices designed for aluminum storefront doors. Compatible with Adams Rite strike configurations.
Common for retail, office lobbies, and commercial entry doors.

Common in access control installations.
Can you handle fire-rated Von Duprin?
Yes. UL-listed fire-rated Von Duprin devices serviced with OEM parts to preserve fire rating. Documentation suitable for NFPA 80 annual inspection.
Dogdown feature restricted on fire-rated models.
What if my dogdown is stuck?
Common Von Duprin issue. Dogdown mechanism fails from wear or tampering. OEM rebuild kits include replacement dogdown components.
In-field repair possible for most models. Don't use non-OEM rebuild kits on fire-rated devices.
Can you do pair door SVR/CVR?
Yes. SVR (surface vertical rod) and CVR (concealed vertical rod) exit devices for pair doors. More complex than rim devices but serviced with OEM parts.
Less forgiving of misalignment - strike positioning matters.
Do you stock Von Duprin parts?

Most Von Duprin service completed in single visit with stock parts.
Can you convert mechanical to electric?

Evaluation during site visit.
How long do Von Duprin devices last?
Grade 1 Von Duprin devices: 15-30 years with proper maintenance. 98/99 particularly durable. Many Treasure Coast commercial devices operating 20+ years.
Rebuild during life extends service significantly. Replace when parts become scarce or multiple issues emerge.
