Von Duprin 9857-F-3-626 – Frequently Asked Questions

1) What does three-point latching actually do compared to a standard vertical rod exit device?
A three-point latch bolts the door at the head, the threshold, and the lock edge. The top and bottom bolts are deadlocking anti-friction with a 5/8 inch throw, and there is also a deadlocking rim bolt with a 3/4 inch throw at the strike edge. A two-point surface vertical rod device latches only top and bottom. The third point at the lock edge pulls the free edge of the leaf tight, which is why these get specified on wide institutional openings where a long leaf can flex.
2) Do I need to specify handing when ordering the Von Duprin 9857-F/9957-F-3?
The device itself is non-handed, so the chassis works either hand. Handing enters at two places. If you specify the SS signal switch or the WS windstorm option, the device becomes handed. And the outside trim is handed on several options: NL night latch, L lever, L-BE and L-NL are all ordered LHR or RHR. Know the door swing before you pick trim.
3) Is the Von Duprin 9857-F/9957-F-3 fire rated for a fire door assembly?
Yes, the F in the model number is the fire rated build, UL listed per ANSI/UL 10C for fire exit hardware and also compliant with ANSI/UL 305, CAN/ULC-S104 and CAN/ULC-S132 for Canadian work. It carries ANSI/BHMA A156.3 2014 Grade 1. Fire exit hardware has no mechanical dogging, so plan on the door latching every cycle.
4) How much does a Von Duprin 98/99 three-point latch stick out into the opening?
Projection is 3-13/16 inches off the door face, and the center case measures 8 x 2-3/4 x 2-3/8 inches. That projection is the number to check against a corridor width, a adjacent wall return, or a door that swings into a tight vestibule.
5) What is the difference between the Von Duprin 9857-F and the 9957-F?
Mechanism case only. The 9857-F is the 98 Series smooth case, the 9957-F is the 99 Series grooved case. Function, latching, ratings and dimensions are the same. Pick whichever matches the devices already on the other openings in the building. Both come in the same twelve finishes, from 605 bright brass and 626 satin chrome through 630 satin stainless, 710 dark bronze anodized and 711 flat black.
6) What outside trim options can I order with the Von Duprin 9857-F/9957-F-3?
Trim is a required selection. Exit only (EO) has none. Otherwise you can order 990DT dummy trim, 990NL-R/V night latch, NL-OP night latch cylinder with the 110MD/WD pull, 990TP thumbpiece or TP-BE with blank escutcheon, 996K knob or K-BE and K-NL versions, 996L lever with the same BE and NL variants, or the 990DT/374T turn lever in plain or blank escutcheon. Lever trim defaults to the 06 lever, with 03, 07, 17 and the Latitude LAT lever available.
7) Can I change the function of a Von Duprin 98/99 exit device in the field?
Yes. EO, DT and NL are field selectable on the device, so a locksmith can switch between exit only, dummy trim and night latch without a different chassis. For TP, K or L trim functions, you remove the NL drive screw from the device. That matters for a facility standardizing stock: one device covers several openings and the trim decides the function.
8) What electrified options are available on the Von Duprin 9857-F/9957-F-3 for access control?
For tying the device into access control you can specify LX latch bolt monitor, RX request to exit or RX2 double request to exit, WP-RX waterproof request to exit, E electric locking and unlocking trim, EL electric latch retraction or QEL quiet electric latch retraction, SS signal switch, and ALK alarm exit kit. Note that SS makes the device handed.
9) Will the Von Duprin 9857-F/9957-F-3 latch into my existing strikes?
The rim bolt at the lock edge throws 3/4 inch and the top and bottom bolts throw 5/8 inch, both deadlocking and anti-friction. Those throws are what your existing head strike, threshold strike and lock edge strike have to accept. On a fire door assembly the strikes are part of the listed assembly, so a three-point conversion normally means new strikes and a new threshold strike rather than reusing what is in the frame.
10) How do I protect the bottom rod on an exit device in a hospital corridor with carts and gurneys?
Bottom rod damage from cart and gurney strikes is a known problem on vertical rod devices, and vertical rod guards and latch guards are available for the 98/99 platform to shield the lower rod. For the door hardware itself, the mechanical options list includes SNB sex bolts and SEC security screws for abuse-prone openings, plus WH weep holes for exterior doors that take water.
11) Can an existing Von Duprin 98/99 device be upgraded with a dogging indicator or delayed egress?
The 98/99 platform accepts a range of retrofit options: CDSI and HDSI dogging indicators, QEL quiet electric latch retraction, RX and LX electronic switches, the AX accessible device upgrade, CX delayed egress (CHEXIT), and the XP patented two-piece latchbolt. That is useful when a facility is bringing older 98/99 openings up to a new access control or egress standard without replacing the whole device line.
