Von Duprin 51860 – Frequently Asked Questions

1) What is the Von Duprin 051860 auxiliary fire pin and which exit devices does it go in?
The 051860 is a genuine Von Duprin auxiliary fire pin, a small installation component used inside fire-rated exit devices set up as LBR (less bottom rod) or LBL (less bottom latch). It fits the 33/35 Series 47-F, 47WDC-F and 49-F, the 98/99 Series 47-F, 47WDC-F and 49-F, and the 94/95 Series 47-F and 48-F. It is not the latch, the rod, or the chassis, it is the auxiliary pin that goes with those fire-rated device configurations.
2) Do I need an auxiliary fire pin if my exit device is ordered less bottom rod?
That is exactly the case this part exists for. When a fire-rated vertical rod device is furnished LBR or LBL, the bottom rod and bottom latch are deleted, and the auxiliary fire pin takes over the securing function at the bottom of the door that the deleted bottom hardware would have handled. If your device is a standard fire-rated vertical rod device with the bottom rod still in place, this pin is not part of that assembly.
3) Will the Von Duprin 051860 fire pin work on a 98/99 rim device or a 33/35 rim device?
No. The 051860 pin is specified for the vertical rod fire-rated models, the 47-F, 47WDC-F and 49-F on 33/35 and 98/99, and the 47-F and 48-F on 94/95, in LBR or LBL form. A rim device latches into a strike on the frame and has no bottom rod to delete, so there is nothing for this pin to do on one. Match the device model stamped on your existing chassis before ordering.
4) Can a Falcon 610061 concealed vertical top rod be used in place of the Von Duprin 051860 auxiliary fire pin?
No - they are different parts of a concealed vertical rod assembly. The Von Duprin 051860 is an auxiliary fire pin used with 33/35, 98/99, and 94/95 Series LBR and LBL exit devices, a small installation accessory internal to the device. The Falcon 610061 is a concealed vertical top rod for Falcon F-25-C and F-25-CWDC exit devices in the 245 Series. A rod transmits latch motion the length of the door; the fire pin does not, and neither one substitutes for the other. If you are servicing a Von Duprin LBR or LBL device, order the Von Duprin part; the Falcon rod fits Falcon 24 Series Monarch devices.
5) What is the difference between the Von Duprin 051860 auxiliary fire pin and the Accentra 7110F top latch replacement component?
Both are exit device service parts, but they are not interchangeable and they sit in different places in the device. The Von Duprin 051860 is an auxiliary fire pin for Von Duprin 33/35 Series (47-F, 47WDC-F, 49-F), 98/99 Series (47-F, 47WDC-F, 49-F), and 94/95 Series (47-F, 48-F) LBR and LBL devices. The Accentra 60-7010-0050-999 is a top latch replacement component for the Accentra 7110F exit device, and Accentra also offers 60-7010-0049-999 as the top latch component for the 7110/7120. Match the part to the brand and series stamped on the device you are repairing - a Von Duprin device takes the Von Duprin component, and an Accentra 7110F takes the Accentra one.
6) Is the Von Duprin 051860 an OEM part or an aftermarket copy?
Genuine Von Duprin factory component, sourced from Von Duprin. For a fire-rated opening that matters more than usual, since the pin is part of the assembly the device was listed with, and a facility inspecting fire door assemblies wants OEM hardware on record rather than a look-alike.
7) I need a replacement part for a non-Von Duprin exit device, what are my options?
The 051860 pin is Von Duprin only, keyed to their 33/35, 98/99 and 94/95 device models, so it will not cross over. For other brands ZenSupply carries device-specific service parts too: Accentra top latch replacement components for the 7110/7120 and for the 7110F, and the Falcon 610061 concealed vertical top rod for the 24 Series Monarch F-25-C and F-25-CWDC devices. Each of those is tied to its own device family the same way this pin is, so start from the model stamped on your chassis.
8) Can I use the 051860 fire pin instead of a mullion on a pair of doors?
Different jobs entirely. The auxiliary fire pin is an internal component of an LBR or LBL vertical rod device on a single leaf. If what you actually need is to secure a pair of doors, that is a mullion, and ZenSupply stocks the Falcon 4023 steel mullion for double door exit device applications, plus Falcon 525 aluminum mullion stabilizers. Buying the pin will not solve a pair-of-doors problem.
9) Does the 051860 fire pin cover both the 98/99 and the older 33/35 devices, or do I need a different pin for each?
One part number covers all three families in the listed fire-rated models: 33/35 Series 47-F, 47WDC-F and 49-F, 98/99 Series 47-F, 47WDC-F and 49-F, and 94/95 Series 47-F and 48-F. If you are standardizing service stock across a building that has a mix of 33/35 and 98/99 devices in LBR or LBL trim, this is a single pin to carry rather than three.
10) My double doors have no center post - do I need the 051860 auxiliary fire pin or a mullion?
Those solve different problems. The Von Duprin 051860 auxiliary fire pin is an internal service component for 33/35, 98/99, and 94/95 Series LBR and LBL exit devices already hung on the door. A pair of doors without a fixed center post needs a mullion instead: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are an exit device accessory for mullion installations. If the opening is missing its center post, start with the mullion; the fire pin only comes into it when you are rebuilding the exit device itself.
11) Will the Von Duprin 051860 fire pin change the keying or cylinder on my exit device?
No. The 051860 is a commercial installation accessory for Von Duprin 33/35, 98/99, and 94/95 Series LBR and LBL exit devices and has nothing to do with the cylinder. Keying work on a rim exit device is a separate part: the Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin for Arrow 24/25 Series, which is the kind of component you change when you are altering the cylinder or moving a device onto a small format interchangeable core system. Ordering the 051860 will not affect the keyway, the core, or the trim.
12) Is the Von Duprin 051860 fire pin rated for heavy commercial traffic?
Grade 1 and classified for commercial use, so it belongs on the same high-traffic openings the 98/99 and 33/35 devices themselves serve, schools, hospitals, offices, government buildings, and multi-tenant residential.
13) Is a Falcon T Series deadlatch replacement part an alternative to the Von Duprin 051860?
No. The Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for Falcon T Series locks - a latch that goes into the door edge prep on a cylindrical lockset. The Von Duprin 051860 auxiliary fire pin belongs to exit device hardware, serving 33/35, 98/99, and 94/95 Series LBR and LBL devices. If the door has a push bar, you are in exit device parts and the 051860 applies; if it has a lever or knob lockset with a 2-3/8 inch backset, the T Series deadlatch is the part in play.
