Von Duprin 90036 – Frequently Asked Questions

1) What does the Von Duprin 090036 spring actually do on a 33 or 35 Series exit device?
The 090036 is the cover plate anti-rattle spring for Von Duprin 33 and 35 Series exit devices. It puts tension behind the cover plate so the plate stops shifting and rattling against the device body when the door swings or slams. If you have a bank of 33/35 devices where the cover plates buzz or shift under traffic, this is the part that fixes it, not the pushpad or the latch. It is a genuine Von Duprin replacement component.
2) Is the Von Duprin 090036 spring OK to use on a fire rated exit device opening?
The 090036 anti-rattle spring is not fire rated. On a labeled opening, every component in the exit device assembly has to be part of the listed configuration, so if the door carries a fire label, source the cover plate spring through the fire rated 33A/35A parts path rather than assuming this one carries over. For non-labeled commercial openings, which is most egress-only exterior and corridor doors, it is the correct 33/35 cover plate spring.
3) Is a rattling exit device cover plate a spring problem or does the whole device need replacing?
Start with the spring. On a 33 or 35 Series, a cover plate that shifts, buzzes or sits loose is usually a fatigued or missing anti-rattle spring, and the 090036 replaces it without touching the pushpad, the latch or the mounting. If the pushpad travel feels wrong or the latch is not throwing, that is a different failure and the spring will not correct it. Replacing one small spring beats replacing a Grade 1 device that is otherwise sound.
4) Will a Falcon exit device part work as a substitute for the Von Duprin 090036 anti-rattle spring?
No. The Von Duprin 090036 is a cover plate anti-rattle spring for 33 and 35 Series exit devices, and it is series-specific to that chassis. The Falcon parts that sit closest to it in an exit device teardown solve different problems: the Falcon 610061 is a concealed vertical top rod for F-25-C and F-25-CWDC devices, the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 is a set of aluminum mullion stabilizers. A rod, a mullion, and a stabilizer all address door or opening hardware rather than the fit of a cover plate on the push rail, so none of them substitutes for the 090036 spring.
5) My exit devices rattle on a pair of doors with a mullion. Is an anti-rattle spring the right fix, or do I need mullion hardware?
It depends on what is moving. The Von Duprin 090036 anti-rattle spring takes movement out of the cover plate on a 33 or 35 Series device, so it is the fix when the noise is coming from the device itself on the door face. If the movement is in the removable mullion between the two leaves, that is a different part: the Falcon 525 is an aluminum mullion stabilizer for exit devices, and the Falcon 4023 is a steel mullion for double door exit device applications. On a rattling pair, put a hand on the cover plate and then on the mullion before ordering, because the two symptoms take different parts.
6) The latch on my exit device is worn, not just noisy. What do I order instead of an anti-rattle spring?
A worn latch is a latching component, not a cover plate issue, so the 090036 anti-rattle spring will not correct it. Latch-side replacement components are brand and series specific: the Accentra 60-7010-0049-999 is a top latch replacement component for 7110 and 7120 exit devices, the Accentra 60-7010-0050-999 is the top latch replacement component for the 7110F, and the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for T Series. Identify the device brand and series on the chassis first, because a latch part from one line does not cross to another.
7) Von Duprin 090036 comes as a pack of 10 - can I buy just one spring?
The 090036 ships as a 10-pack. That is the order unit, so a single spring is not sold on its own. For a maintenance shop running 33/35 devices across a portfolio it works in your favor, since one order covers the door in front of you and stocks the cart for the next nine service calls.
8) Is the Arrow 16RCR-27 an alternative to the Von Duprin 090036 for a rim exit device?
No, the two parts serve unrelated functions on a rim device. The Arrow 16RCR-27 is a 6/7-pin SFIC rim housing, which is the cylinder housing that accepts a small format interchangeable core for keyed outside access, and it is an Arrow 24/25 Series part. The Von Duprin 090036 is a cover plate anti-rattle spring for Von Duprin 33 and 35 Series devices and has nothing to do with keying or cylinder prep. A locksmith rekeying an opening wants the SFIC housing; a locksmith quieting a loose cover plate wants the spring.
9) I am servicing a fire rated exit device. Does the 090036 or one of the comparable parts carry a fire rating?
Fire rating on an opening is carried by the device and door assembly, not by these service components. The Von Duprin 090036 anti-rattle spring is a Grade 1 commercial replacement part with no fire rating of its own, and the Accentra top latch replacement components 60-7010-0049-999 and 60-7010-0050-999 are likewise non fire rated components. If the opening is a labeled fire door, confirm the exit device model itself is the fire rated version and keep every component within that device's own parts list rather than mixing lines.
10) We standardize exit device spare parts across a portfolio. Can one anti-rattle spring cover all our devices?
Not across brands. The Von Duprin 090036 is a commercial Grade 1 cover plate anti-rattle spring matched to Von Duprin 33 and 35 Series devices and comes in a pack of 10 for stocking. Buildings running other lines need their own service parts: Accentra 7110, 7120, and 7110F devices take the Accentra top latch replacement components 60-7010-0049-999 and 60-7010-0050-999, Falcon T Series takes the Falcon 23981160 deadlatch part, and Falcon 24 Series Monarch concealed vertical devices take the Falcon 610061 top rod. Standardizing means stocking by device series, so a portfolio survey of chassis brands is the step before the parts order.
11) Is the Von Duprin 090036 spring rated for high traffic commercial doors?
Grade 1 and commercial rated, which is the level specified for high-use openings like school corridors, hospital egress and office building exteriors. It is not a residential-grade part.
12) What other exit device replacement parts should I stock alongside the Von Duprin 090036 spring?
The 090036 only covers the cover plate on 33/35 Series devices, so a service van usually carries parts for the other failure points too. For latch failures on other brands, ZenSupply carries the Accentra 7110/7120 top latch replacement component and the Falcon T Series 2-3/8 inch square corner deadlatch. For pairs of doors, the Falcon 4023 steel mullion and the Falcon 525 aluminum mullion stabilizers cover the mullion side. Concealed vertical rod work on Falcon 24 Series shows up as the 610061 top rod. None of those are interchangeable with the Von Duprin 090036, they are the adjacent parts on the same kind of job.
