Corbin Russwin 412F03-7 – Frequently Asked Questions

1) What does the Corbin Russwin 412F03-7 retaining spring actually do, and which device does it belong to?
The 412F03-7 is a retaining spring for the Corbin Russwin ED6000 Crossbar Exit Device. It is a small internal replacement component, not a complete device or trim, so it is ordered when the crossbar mechanism on an installed ED6000 needs servicing rather than replacing the whole unit.
2) Can I use this part on a fire rated opening without affecting the rating?
The Corbin Russwin crossbar exit device family is UL and cUL listed for panic and 3-hour fire exit hardware and compliant with NFPA 101 and NFPA 80, and it is California State Fire Marshal approved. Using the factory 412F03-7 retaining spring keeps the assembly as listed; a non-OEM spring is where that gets risky on a rated door.
3) Is this a genuine Corbin Russwin part or an aftermarket copy?
It is a genuine OEM Corbin Russwin component, the factory-specified retaining spring for the ED6000 Crossbar Exit Device. On a fire exit device, keeping to factory parts matters because field substitutions can put the UL listing of the assembly in question.
4) Does replacing a spring on a crossbar exit device depend on the handing of the door?
Corbin Russwin crossbar exit devices are non-handed as standard, with only double cylinder and lever trim versions being handed. The retaining spring is an internal mechanism part, so you order the same 412F03-7 regardless of which way the door swings; handing only comes into play when you are also replacing lever trim or a double cylinder device.
5) Do I need to order anything else with the 412F03-7 retaining spring to finish the repair?
The 412F03-7 covers the retaining spring only. If the crossbar itself is the issue, note the bar comes in a 36 inch standard length that fits 30 to 36 inch doors and can be field cut, with 24 inch and 48 inch options. Strike problems are a separate part as well, the surface mounted 3/8 inch roller strike with locking plate and shims.
6) Is this part suitable for a commercial building or is it a residential item?
It is a commercial door hardware part. The ED6000 crossbar devices it serves are ANSI/BHMA A156.3 Grade 1, the highest grade for exit devices, and are used in offices, schools, healthcare, retail, industrial, multi-tenant residential and government buildings.
7) My crossbar device sits too far off the door face. Will a new retaining spring change the projection?
No. Projection on these crossbar devices is 3-1/4 inches (83mm) active and 2-3/4 inches (70mm) when dogged down, and that is fixed by the device geometry. The 412F03-7 restores correct spring action in the mechanism; it does not alter how far the bar stands off the door.
8) If the hex key dogging on my Corbin Russwin crossbar device stopped holding, is the retaining spring the fix?
These devices use single-point 1/4-turn hex key dogging as standard, with cylinder or electric dogging as options. Dogging faults are usually in the dogging assembly itself rather than the retaining spring, so pull the cover and confirm which component has failed before ordering the 412F03-7.
