Von Duprin 051707 – Frequently Asked Questions

1) What does the Von Duprin 5547WDC extension rod kit actually do, and when do I need one?
It's the extension rod kit that lets a Von Duprin 55/88 Series vertical rod exit device work on a door taller than standard. Standard vertical rod devices ship with rods cut for a 7 foot door; on an 8 to 10 foot opening the rods can't reach the head and the threshold, so the top latch never engages. The 5547WDC (part 051707) supplies the added rod length for that range. It's an installation accessory only, not a device, so you order it alongside the exit device or to fix an existing one, not instead of it.
2) Will the Von Duprin 5547WDC extension rod kit fit a Precision, Falcon, or Yale exit device?
No. The 5547WDC is engineered as a direct-fit part for the Von Duprin 55/88 Series and nothing else. Vertical rod devices from other makers use their own rod diameters, top latch geometry, and rod-to-device connections, so a Von Duprin kit won't drop into them. If you're extending a Falcon 24 Series Monarch concealed vertical rod device, the part in that family is the Falcon 610061 top rod for F-25-C and F-25-CWDC devices.
3) Is the Von Duprin 051707 extension rod kit fire rated?
No. The 5547WDC extension rod kit carries no fire rating. If the tall opening you're working on is a fire door assembly, that's a decision to settle with the device and label before you order rods, because a non-rated component on a labeled opening is a code problem at inspection, not a fit problem.
4) What is the equivalent extension rod for a Falcon concealed vertical rod exit device instead of the Von Duprin 5547WDC?
The Von Duprin 051707 5547WDC extension rod kit is built for the Von Duprin 55/88 Series exit device line, so it belongs on a Von Duprin device. On the Falcon side, the comparable rod part is the Falcon 610061, a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices, catalogued under the 245 Series. Rods are matched to the device family that drives them, so the choice follows the device already in the door: Von Duprin 55/88 takes the 5547WDC kit, a Falcon F-25-C or F-25-CWDC takes the 610061 top rod.
5) How do I order the Von Duprin tall door extension rod kit, and are there options to pick?
One part number covers it: Von Duprin 051707, the 5547WDC kit. There's no finish, handing, or length choice to make, since the single kit spans the whole 8 to 10 foot range. Order one kit per vertical rod device you're extending, not one per opening, because a pair of doors with two devices needs two.
6) The top latch on my tall door exit device stopped catching. Is a rod kit the fix?
Only if the rods are the problem. On an 8 to 10 foot door running a Von Duprin 55/88 Series device, short or wrong-length rods are a common cause and the 5547WDC kit is what corrects that. If the rods reach fine and the latch itself is worn or broken, you need the top latch assembly, not rods. Accentra 7110/7120 and 7110F owners have their own top latch replacement components; the Von Duprin part is a separate item from this kit.
7) I'm standardizing exit hardware across a building with a mix of 7 foot and 10 foot doors. Can I use the same Von Duprin device everywhere?
Yes, and that's the point of the 051707 kit. You spec the same 55/88 Series vertical rod device on every opening and add the 5547WDC extension rod kit only on the leaves between 8 and 10 feet. Your standard openings take the device as supplied. One device family across the building means one set of parts to stock and one trim standard, with the tall openings handled by an accessory rather than a different product.
8) For a pair of doors, do I need extension rods or a mullion?
Those answer two different questions about the opening. The Von Duprin 051707 5547WDC extension rod kit addresses door height, supplying the added rod length a 55/88 Series vertical rod exit device needs on an 8 foot to 10 foot door. A mullion addresses the width of a double door opening and gives each leaf a strike to latch into: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are accessories for exit device mullions. A tall pair of doors can call for both -- the mullion for the opening and the rod kit for the height.
9) Can a top latch replacement part be used instead of an extension rod kit on a tall door?
No, those solve different problems. The Von Duprin 051707 5547WDC is an extension rod kit that adds the rod length a vertical rod exit device needs to reach across an 8 foot to 10 foot door height. A top latch component, such as the Accentra 7110/7120 exit device top latch replacement component or the Accentra 7110F top latch replacement component, replaces the latching mechanism at the head of the door and does not change how far the rod has to travel. If the door is taller than standard, the rod length is what has to change; if the latch itself is worn or damaged, the latch component is the part to order.
10) Will a deadlatch replacement part fix a vertical rod exit device that will not latch at the top of a tall door?
A deadlatch part such as the Falcon T Series 2-3/8 inch square corner deadlatch replacement part is a T Series latch component and works at the lock edge of the door, not at the head. On a vertical rod device, the top latch is driven by the rod running up the door, so on an 8 foot to 10 foot opening the rod length is what determines whether the top latch reaches and engages. That is the job of the Von Duprin 051707 5547WDC extension rod kit for 55/88 Series exit devices.
