Von Duprin 7527EO 4 626 – Frequently Asked Questions

1) Will the Von Duprin 7527 surface vertical rod device work on an aluminum storefront door with a narrow stile?
That's exactly what the 7527 is built for. It's a narrow stile surface vertical rod device, which is the configuration that fits the slim vertical rail on aluminum storefront and glass front doors where a wide stile device simply has no metal to mount to. Door thickness is 1-3/4 inches. If you're working a wood door, stop here: the 7527 is not rated for wood door use.
2) Do I need a mullion between a pair of doors if I use the Von Duprin 7527?
No mullion needed. A surface vertical rod device latches into the head frame at the top and the floor or threshold at the bottom, so each leaf secures itself independently. That's the whole reason people pick SVR over a rim device on a pair: a rim device latches into a strike on the frame or a removable mullion, which means either a mullion in the middle of your opening or a second leaf that can't open freely. The tradeoff is the exposed rods and two strike locations to keep aligned.
3) My floor strike keeps getting damaged by carts. Can I order this Von Duprin without a bottom rod?
Yes, less bottom rod is an option on the 7527. LBR drops the bottom rod and floor strike entirely, so the device latches only at the head. That's the standard move in warehouses, loading areas, and anywhere pallet jacks or carts chew up a threshold strike, and it also avoids problems where the floor is uneven or carpeted. With the bottom rod in place, the device uses a 299 top strike and a 304L bottom strike.
4) Will the Von Duprin 7527 latch into my existing top strike?
The 7527 throws its latch 3/4 inch and is set up for a 299 top strike with a 304L bottom strike. If your frame is already prepped for those, you're a straight swap. If it's prepped for a different device's strike, plan on replacing the strike and possibly reworking the head prep. There's also a strike choice at order time: the 1439 roller strike is the default, and the 299 is the one to pick for hollow metal doors.
5) What outside trim options come with the Von Duprin 7527, and which one do I want for a storefront entrance?
Nine trim functions are available on the 7527. EO is exit only, no outside trim at all, for a pure egress door. NL is night latch, a key retracts the latch to get in, and NL-OP adds a pull. L is a lever that unlocks with a key, L-BE puts the lever on a blank escutcheon, L-DT is a lever plus dummy trim. TL is a thumbturn that unlocks, T-BE a thumbturn on a blank escutcheon, and DT is dummy trim, a pull that never operates the device. For a storefront front door where staff key in, NL or NL-OP is the usual call; where you want free passage when unlocked, spec the L lever. Lever function also needs a lever design picked from 01, 02, 03, 05, 06, 07, 12, 16, 17, or 18.
6) Can the Von Duprin 7527 tie into my access control system, and what do I specify?
Yes, two ways, and they solve different problems. For monitoring and signalling, order a switch: RX for request to exit, LX for latchbolt monitoring, LX-RX for both, RX2 for a double RX switch, or WP-RX where the device sees weather. ALK adds an alarm exit kit, available less switch, with RX, or with both LX and RX. For remote unlocking, QEL is quiet electric latch retraction, which holds the latches retracted electrically instead of mechanically dogging the device, and it's the option to pick when the noise of standard electric latch retraction is a problem, like a hotel lobby or a library. HD-QEL pairs QEL with hex dogging on panic devices, and QELX and HD-QELX are the versions for AX accessible devices.
7) Should I buy a narrow stile or wide stile surface vertical rod exit device?
It's decided by the door, not by preference. Narrow stile devices like the Von Duprin 7527 mount on the slim rails of aluminum storefront and glass entrance doors, where a wide stile chassis physically won't land. Wide stile devices need the broader rail you get on hollow metal and most wood doors. If your door is hollow metal or wood, wide stile options include the Corbin Russwin ED5400 Grade 1 for 1-3/4 inch doors, the Falcon 20 Series Grade 1, and the Sargent 3727 Grade 1. If it's storefront, stay narrow stile: the Corbin Russwin ED4400 and the Falcon 19-V-EO are Grade 1 narrow stile alternatives, both listed at 1-3/4 inch door thickness.
8) The 7527 is not fire rated. What surface vertical rod device should I use on a fire rated opening?
The Von Duprin 7527-4ft as configured carries no fire rating, so on a labeled opening the device has to come from a fire rated family. Fire rated surface vertical rod peers include the Adams Rite 3100 Series, fire rated Grade 1 wide stile for 1-3/4 inch doors, the Arrow S1150, fire rated exit only for 1-3/4 inch doors in narrow or wide stile, the Sargent 2727, a Grade 1 fire rated reversible wide stile exit only device, and the TownSteel 9700 Series EF9727, a fire rated Grade 1 heavy duty wide stile device that is wood door compatible. The Arrow S1150 is the one to look at first when the stile is narrow, since it covers both narrow and wide stile applications.
9) What is the closest narrow stile surface vertical rod equivalent to the Von Duprin 7527 from another manufacturer?
The Von Duprin 7527 is a Grade 1 narrow stile surface vertical rod device for 1-3/4 inch doors. The closest like-for-like narrow stile Grade 1 SVR peers are the Corbin Russwin ED4400, also Grade 1 narrow stile for 1-3/4 inch doors and built to accept trim, the Falcon 19-V-EO, Grade 1 narrow stile for 1-3/4 inch doors in an exit only function, and the Adams Rite 8200 Series, a Grade 1 narrow stile life-safety SVR device. If the opening has a narrow aluminum stile and needs trim on the outside, the ED4400 is the nearest match in stile type, grade and door thickness.
10) The Sargent 12-8710 came up as an alternative to the Von Duprin 7527. Is it an equivalent?
No. The Sargent 12-8710 in the 8700 Series is a dummy function fire rated wide stile surface vertical rod device, which means it provides the appearance and push of a device without latching or releasing. The Von Duprin 7527 is an active narrow stile Grade 1 device with a 3/4 inch latch throw working against a 299 top strike and 304L bottom strike. A dummy device belongs on the inactive leaf or a pull-side match, not on an egress door that has to latch. The 7527 itself can be ordered with DT dummy trim if what is needed is dummy trim on the outside of an active device.
11) Which vertical rod exit device should I choose if I need electric latch retraction and request to exit monitoring?
The Von Duprin 75 Series 7527 can be ordered with QEL quiet electric latch retraction, including HD-QEL with hex dogging and QELX for AX accessible devices, and with switch options covering RX request to exit, LX latchbolt monitor, LX-RX, RX2, WP-RX waterproof RX, and ALK alarm exit kit variants. Dogging is available as hex key, CD cylinder dogging, or LD less dogging. The comparable devices in this group are specified as mechanical exit devices, with the Corbin Russwin ED7400 accepting operator trim. If the opening is on an access control system and needs both latch retraction and egress monitoring from one device, the 7527 handles both in a single order.
12) What is hex key dogging on the Von Duprin 7527, and can I get cylinder dogging instead?
Hex dogging is the standard setup: an Allen wrench holds the push pad depressed so the latches stay retracted and the door pushes open freely, which is how you leave a storefront unlocked during business hours. Anyone with a hex key can do it. If you want that controlled by key instead, order CD for cylinder dogging, which takes a mortise cylinder so only keyholders can dog the device. LD, less dogging, deletes the function altogether, which is what you specify when building policy or the AHJ doesn't want the door held latch retracted.
13) How far does the Von Duprin 7527 stick out from the door face, and where does it mount?
Projection is 3-13/16 inches off the door face, which matters if the door swings into a tight vestibule, next to a wall return, or where a second leaf or handrail is close by. Device centerline sits at 39-13/16 inches from finished floor, so mark your template from the floor, not from the top of the door, and it will line up across a run of openings.
14) Is the Von Duprin 7527 Grade 1, and what does that mean for a high traffic entrance?
Grade 1 to ANSI/BHMA A156.3, 2014, which is the top tier in the exit device standard and the one specified for heavy use commercial openings. It's also certified to ANSI/UL 305 and CAN/ULC-S132 for panic hardware. If you're standardizing a school, a hospital, or a municipal building, Grade 1 is typically what the spec calls for on egress doors, and the 7527 is a commercial device, not a light duty one.
15) What is the AX accessible device option on the Von Duprin 7527?
AX is an ordering choice on the 7527, yes or no, and it changes the internal mechanism to one requiring less force to operate the push pad. Facilities standardizing to accessibility requirements across their entrances specify it. If you choose AX and also want electric latch retraction, the matching options are QELX or HD-QELX rather than the standard QEL.
16) Is a crossbar vertical rod exit device like the Corbin Russwin ED7400 a substitute for the Von Duprin 7527?
They latch the same way but they are not the same device to the hand or to the eye. The Von Duprin 7527 is a push pad style device in narrow stile, Grade 1, for 1-3/4 inch doors. The Corbin Russwin ED7400 is a Grade 1 narrow stile surface vertical rod device with a crossbar actuator, also for 1-3/4 inch doors, and it accepts operator trim. If the other doors in the building are push pad, the ED7400 changes the look and the touch point even though the grade, stile type and door thickness match. For a push pad match in narrow stile, the Corbin Russwin ED4400 is the closer pick.
17) I need a lighter duty vertical rod exit device than the Grade 1 Von Duprin 7527 for a low traffic door. What are the options?
The Von Duprin 7527 is certified to ANSI/BHMA Grade 1. Where the opening does not need Grade 1, the Dexter ED2000 Series is a Grade 2 surface vertical rod panic device, and the TownSteel TS5100 Series is a Grade 2 heavy duty wide stile surface vertical rod device. The Design Hardware 2000V is a standard duty surface vertical rod device, with the 1000V as the heavy duty build in the same line. None of these four carry a fire rating, so keep them off labeled openings.
18) I need a non-handed or reversible vertical rod exit device. Which comparable devices are reversible?
Reversibility matters when one device has to cover both hands of a pair or when the hand is not confirmed at order time. Among the comparable surface vertical rod devices, the BEST Precision 5201 Series is a reversible surface vertical rod device, the Sargent 2727 is a Grade 1 fire rated reversible wide stile exit only device, and the Orca Hardware OED56 is a non-handed exit only device supplied less bottom rod in aluminum finish for 1-3/4 inch doors. The Von Duprin 7527 can also be ordered less bottom rod if the bottom rod is the issue rather than the handing.
19) I need trim with a lever on the outside of the door. Which vertical rod devices accept trim and which are exit only?
The Von Duprin 7527 covers trim functions including L lever, L-BE lever with blank escutcheon, NL night latch, TL thumbturn and unlocks, and DT dummy trim, with lever designs from 01 through 18. Among the comparables, the Corbin Russwin ED4400 and ED5400 are exit only devices that accept trim, and the ED7400 accepts operator trim. Devices listed as exit only without trim provision include the Falcon 19-V-EO, the Falcon 24-V-EO, the Arrow 3700 Series, and the Arrow S1150, which is supplied less trim. Confirm the trim function before substituting, because an exit only device leaves no outside operation on the door.
20) What finishes does the Von Duprin 7527 come in to match the other doors in my building?
Ten finishes on the 7527: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 643E aged bronze, 710 dark bronze anodized, and 711 flat black. For matching an existing run of aluminum storefront, 628 aluminum and 710 dark bronze anodized are the two that track the common anodized frame colors. 626 satin chrome is the usual default on institutional openings.
