75/78 Series Exit Devices
The Von Duprin 75 and 78 Series are the two halves of the Von Duprin 70 Series: the 75 has a narrow stile pushpad and the 78 a wide stile pushpad. Shop the 78EO and 75EO rim devices, the 7527EO and 7827EO surface vertical rod devices and the 7547EO, 7847EO and 7847WDCEO concealed vertical rod devices.
Von Duprin 75 vs 78: narrow stile or wide stile
The difference between the 75 and 78 is the width of the pushpad and the door it suits. The 75 Series is listed as narrow stile, for aluminum storefront doors with narrow stiles, and the 78 Series as wide stile, for hollow metal and wood doors. Every device in this category is listed as Grade 1, certified to ANSI/BHMA A156.3 2014 and UL listed for panic exit hardware, with hex key dogging and a non-handed design.

Rim, surface rod or concealed rod?
Choose the device type by the door. Rim devices (75, 78) latch into a strike on the frame and suit single doors and pairs with a mullion. Surface vertical rod devices (7527, 7827) latch at the top and bottom of the door and suit pairs without a mullion; the listings note that rod and latch guards are available to protect the bottom rod. Concealed vertical rod devices (7547, 7847) hide the rods in metal doors, and the 7847WDC is the version for wood doors.
Device size and door width
Von Duprin lists the device lengths by door width: a 3' device for doors from 2'6" to 3' (762 to 914 mm) and a 4' device for doors from 3' to 4' (914 to 1219 mm). The concealed rod devices in this category are listed as 36" (3') devices. Measure the door before ordering.
EO means exit only: adding trim
All devices here are EO, exit only, so there is no outside trim and the door cannot be opened from outside. If the door needs entry, order the device with a trim function or add a compatible Von Duprin trim, and check the device catalog for the trims that fit the 75 and 78. The exit device trims category lists the options.
Covering old cutouts on hollow metal doors
When an old lock or device is replaced, the door may have a mortise cutout left over. The 78EO and 7827EO listings say they cover stock hollow metal doors with 86 or 161 cutouts, which helps when upgrading a door that had a mortise lock or a different exit device.
Dogging and electric options
Hex key dogging lets staff hold the latch retracted so the door works as push/pull during the day. The devices here are listed with hex key dogging and are non fire rated in that configuration. The 70 Series can also be configured with options such as Quiet Electric Latch Retraction, according to the current category description; check with us for availability on a specific model.

Frequently Asked Questions
Is the Von Duprin 78 a Grade 1 exit device?
Yes. The 78 Series devices in our catalog are listed as Grade 1, certified to ANSI/BHMA A156.3 2014, and UL listed for panic exit hardware. The same applies to the 75 Series narrow stile devices.
Are Von Duprin 75/78 devices handed?
No. The devices in this category are listed as non-handed, so they fit left or right hand doors. Trims and some accessories may be handed, so check the trim listing and the door hand when you add one to the device.
What is the difference between the Von Duprin 70 Series and the 98/99 Series?
Both are Grade 1 Von Duprin lines. The 98/99 Series is the long-established heavy duty line with the widest choice of functions, options and fire rated versions, while the 70 Series, made up of the 75 narrow stile and 78 wide stile devices, is a newer line with a narrower range of options.
