Von Duprin 040074 313 – Frequently Asked Questions

1) Which size do I order, the 36 inch or the 48 inch cylinder dogging kit?
Match the size to the device length already on the door. The kit comes in a 36 inch version and a 48 inch version, corresponding to 36 inch and 48 inch door configurations for 35A devices. Measure the existing Von Duprin 35A pushbar assembly (or the door width it was supplied for) before ordering, since the two are not interchangeable.
2) Can I use this Von Duprin dogging kit on a fire rated exit device?
No. The 040074/040075 conversion kit carries no fire rating, and mechanical dogging is not permitted on fire rated exit devices in any case, since a fire door must latch. Use it only on non-rated openings such as main entrances, corridor doors, and storefront-type exits.
3) My exit device will not latch at the top of the door - is the Von Duprin 040074/040075 the part I need?
No. The Von Duprin 040074/040075 converts 33 and 35 Series 35A devices to cylinder dogging with an indicator; it does not affect latching. For a top latching problem on a vertical rod or top latch device, the corresponding part is the latch or rod assembly itself, such as the Accentra 60-7010-0049-999 top latch replacement component for 7110/7120 devices, the Accentra 60-7010-0050-999 top latch for the 7110F, or the Falcon 610061 concealed vertical top rod for 24 Series F-25-C and F-25-CWDC devices. Match the replacement to the device brand and model already on the door.
4) Can an Arrow 16RCR-27 SFIC rim housing be used instead of the Von Duprin 040074/040075 cylinder dogging kit?
No. The Von Duprin 040074/040075 is a cylinder dogging with indicator conversion kit for Von Duprin 33 and 35 Series exit devices, specifically 35A devices on 36 inch and 48 inch doors, and it changes how the device is held in the dogged position. The Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin configuration for the Arrow 24/25 Series, which holds a small format interchangeable core for rim cylinder use. One converts the dogging mechanism, the other carries a core, so they are not interchangeable even though both involve a cylinder.
5) We have fire-rated exit doors in our building - is the Von Duprin 040074/040075 the right dogging kit for them?
The 040074/040075 cylinder dogging with indicator conversion kit carries a fire rating of No, so it is intended for non-fire-rated openings, where mechanical dogging is permitted. Several comparable exit device components are in the same position, including the Accentra 60-7010-0049-999 and 60-7010-0050-999 top latch replacement parts, both listed with a fire rating of No. On fire-rated exit doors the device must latch on every cycle, which is why dogging conversions belong on non-rated openings such as main entries and interior traffic doors.
6) What finishes does the 040074/040075 dogging kit come in so it matches the rest of my exit devices?
Nine finishes, in both the 36 inch and 48 inch lengths: 605 bright brass, 606 satin brass, 612 satin bronze, 619 satin nickel, 625 bright chrome, 626 satin chrome, 628 aluminum, 710 dark bronze, and 711 flat black. For a fleet of doors, order the finish code that matches the existing Von Duprin devices rather than matching by eye.
7) Is this Von Duprin dogging conversion kit rated for heavy traffic commercial doors?
Grade 1 and designated for commercial use, which is the heavy duty tier for door hardware. That suits it to schools, hospitals, office towers, retail, warehouses, and government buildings where the exit is cycled constantly.
8) Does the cylinder dogging kit include the cylinder itself?
The 040074/040075 is the dogging and indicator conversion assembly for the 35A device. A dogging cylinder is a separate order item, so specify a mortise cylinder in your keyway and keying when you buy the kit if you do not already have one on hand.
9) Can I put the Von Duprin 040074/040075 dogging kit on a Falcon exit device?
No. The 040074/040075 kit is built for Von Duprin 33 and 35 Series exit devices, 35A models specifically, and it is a Grade 1 commercial replacement part matched to that chassis. Falcon exit device components are model-specific in the same way - for example the Falcon 610061 top rod is called out for 24 Series F-25-C and F-25-CWDC devices, and the Falcon 23981160 deadlatch is a T Series part with a 2-3/8 inch square corner. Dogging conversions do not cross brands; specify the kit that matches the device already installed.
10) I need to hold a pair of doors open during business hours - does the cylinder dogging kit work on both leaves, or do I need a mullion?
The Von Duprin 040074/040075 cylinder dogging with indicator conversion kit works on the exit device itself, so each 35A device on 36 inch or 48 inch doors needs its own kit to be dogged. A mullion serves a different purpose entirely: the Falcon 4023 is a steel mullion for double door exit device applications, providing the strike point between two leaves, and the Falcon 525 aluminum mullion stabilizers steady a mullion in service. If your pair currently has no center post, the mullion is the structural piece and the dogging kit is the hold-open control - they address separate needs.
11) My pair of doors uses a removable mullion. Does adding cylinder dogging change anything?
Cylinder dogging only affects the device pushbar, letting staff hold it retracted for free passage. It does not replace or alter the mullion. If you are outfitting a double door opening and still need the mullion itself, that is a separate item, for example the Falcon 4023 steel mullion with 525 aluminum mullion stabilizers for Falcon applications.
