Von Duprin 050112 26D – Frequently Asked Questions

1) Will the Von Duprin 050112 lever arm kit work on a right hand door?
No. The 050112 is the left hand lever arm kit. Lever arms are handed, so a right hand opening needs the right hand version of the kit instead. Determine the hand at the opening before ordering: stand outside the door (the key side), and if the hinges are on your left and the door swings away from you, that is left hand. Fitting a left hand arm to a right hand device puts the lever in the wrong orientation and it will not operate the device correctly.
2) Which Von Duprin exit devices does the 050112 lever arm kit fit?
The 050112 lever arm kit is built for the Von Duprin 55 Series exit device platform, and it covers the rim, mortise, and concealed vertical rod configurations of that series. One kit, three device types, as long as the device is a 55 Series and the opening is left hand. It is not a part for 98/99, 33A/35A, or any other Von Duprin family.
3) Can I use the 050112 lever arm kit on a fire rated exit device?
No. The 050112 lever arm kit carries no fire rating, so it should not go into a labeled fire door assembly. Fire rated openings need parts that are part of the listed assembly, and swapping in an unrated component can void the label on the door. For a non-rated opening, on a 55 Series rim, mortise, or concealed vertical device, it is the correct service part.
4) Is the Von Duprin 050112 a whole lever trim, or just the arm?
It is the lever arm kit, not a complete lever trim assembly. You are buying the replacement arm component that goes into an existing 55 Series device, so the device body, chassis, and the rest of the trim stay on the door. If the lever itself is broken off or the escutcheon is damaged, the arm kit alone will not put the opening back in service.
5) Is the Von Duprin 050112 lever arm kit interchangeable with an Accentra 7110 exit device part?
No. The 050112 is a left hand lever arm kit built for the Von Duprin 55 Series exit device platform, and it fits 55 Series rim, mortise, and concealed vertical rod devices. The Accentra 60-7010-0049-999 is a top latch replacement component for the Accentra 7110/7120 devices, and 60-7010-0050-999 is the top latch component for the 7110F. Those are latch components for a different manufacturer's chassis, not lever arms, so neither one drops into a 55 Series device. Order the 050112 against a 55 Series device and match the hand of the door.
6) I need a concealed vertical rod part for a Falcon exit device, not a Von Duprin. What do I order?
For a Falcon concealed vertical rod device, the Falcon 610061 is the 24 Series Monarch concealed vertical top rod for the F-25-C and F-25-CWDC devices, catalogued in the 245 Series. The Von Duprin 050112 lever arm kit works on the 55 Series platform and covers rim, mortise, and concealed vertical rod 55 Series devices, so the two serve different device families even though both touch concealed vertical rod applications. Identify the device the door already carries before you pick a side.
7) I need to match the finish on the rest of my exit hardware. What finishes does the Von Duprin 050112 lever arm kit come in?
Six finishes on the 050112 kit: 626 satin chrome, 625 bright chrome, 612 satin bronze, 613 oil rubbed bronze, 605 bright brass, and 606 satin brass. For a fleet of openings where the rest of the trim is already 626, order 626 and the arm will read as part of the same set. If you are matching an older brass building standard, 605 and 606 are the two brass options, and 613 is the darkened bronze look.
8) My 55 Series lever is loose and droops. Is replacing the lever arm the fix?
Often, yes. A drooping or sloppy lever on a 55 Series device usually means wear in the arm, and the 050112 kit is the genuine Von Duprin service part for the left hand version. Before ordering, confirm the hand of the opening and confirm the device is a 55 Series, not another Von Duprin family. If the lever turns but the device does not retract the latch, the fault is inside the device chassis and the arm kit will not solve it.
9) I have a pair of doors with 55 Series rim devices and no mullion. Do I need the lever arm kit or something else?
Two separate problems. The 050112 lever arm kit services the outside lever trim on a single 55 Series device; it does nothing to secure a pair of doors. A pair with rim devices needs a mullion between them, and for that you would look at a mullion such as the Falcon 4023 steel mullion for double door exit device applications, with the Falcon 525 aluminum mullion stabilizers where stabilization is needed. Order the arm kit only if the lever trim itself is what has failed.
10) Do I need a different lever arm kit depending on whether my 55 Series is rim, mortise, or concealed vertical rod?
No. One kit covers all three. The 050112 works across 55 Series rim, mortise, and concealed vertical rod configurations, so a facility running a mix of those device types on left hand openings can stock the single part number rather than three. Handing is the variable that matters, not the device configuration.
11) My exit device latch is worn, not the lever. Is the 050112 the right replacement?
Not for a latch. The Von Duprin 050112 is a lever arm kit for 55 Series rim, mortise, and concealed vertical rod devices. If the wear is in the latch, the part class is different: the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the Falcon T Series, and the Accentra 60-7010-0049-999 is a top latch replacement component for the 7110/7120. Match the failed component and the device family, not just the brand on the pushbar.
12) Will a Von Duprin 050112 lever arm kit solve a double door that keeps binding at the meeting stile?
No. The 050112 is a replacement lever arm kit for the 55 Series exit device itself. A double door opening with no fixed center post is a mullion question: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are exit device accessories that address the mullion side of the opening. Use the 050112 to restore a 55 Series device to proper function, and look at mullion hardware for the opening geometry.
13) For a fire rated opening, can I use the Von Duprin 050112 or should I look at the Accentra 7110F part?
Check the device label, not the part alone. The Von Duprin 050112 lever arm kit carries a fire rating of No, and the Accentra 60-7010-0050-999 top latch component for the 7110F also carries a fire rating of No, as does the 60-7010-0049-999 for the 7110/7120. On a labeled opening, the fire listing follows the complete device assembly, so confirm the device and its listed components before you replace anything on that door.
14) Is the Arrow 16RCR-27 rim housing an alternative to the Von Duprin 050112?
They are different parts of the opening. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the Arrow 24/25 Series, which is the cylinder side of a rim device. The Von Duprin 050112 is a left hand lever arm kit for the 55 Series and drives the device from the trim side. A service call that needs keyed access restored takes the cylinder housing; one where the lever arm is the failed component takes the 050112 in the hand that matches the door.
15) I am standardizing exit device service parts across a portfolio. What does the Von Duprin 050112 cover that a single-device part does not?
The 050112 lever arm kit is a Grade 1 commercial part that serves 55 Series rim, mortise, and concealed vertical rod configurations, so one part number covers three device configurations across a 55 Series fleet, in six finishes from 626 satin chrome to 605 bright brass. By contrast, the peer service parts are tied to narrower device families: the Accentra 60-7010-0050-999 top latch is for the 7110F, and the Falcon 610061 top rod is for the F-25-C and F-25-CWDC devices. If the buildings are standardized on 55 Series, the 050112 in the correct hand is a single line item for lever arm service.
16) Is the Von Duprin 050112 lever arm kit rated for a high traffic commercial opening?
Grade 1 and specified for commercial use, so it suits high traffic openings such as school corridors, hospital wings, office towers, and municipal buildings. Grade 1 is the heaviest of the ANSI/BHMA duty grades, which is what you want on a door cycled hundreds of times a day. Note it carries no fire rating, so keep it off labeled openings.
