Corbin Russwin 651F948 – Frequently Asked Questions

1) Will the Corbin Russwin 651F948 spring fit an ED4000 exit device?
Yes. The 651F948 extension spring is the OEM part specified for Corbin Russwin ED4000 series exit devices, and the same spring also serves the ED5000 series. It is sold as a single spring under model number 651F948.
2) My Corbin Russwin push bar is not returning all the way out. Is the extension spring the part to replace?
That is the symptom this part addresses. The 651F948 is the extension spring that provides push-bar return tension on ED4000 and ED5000 devices; when it weakens or breaks, the bar stays depressed or returns sluggishly. Replacing the spring restores the return function without pulling the whole device off the door.
3) Is the 651F948 a genuine Corbin Russwin part or an aftermarket copy?
It is the genuine Corbin Russwin OEM component, part number 651F948, made to the manufacturer's own specification for its ED4000 and ED5000 exit devices. That matters on life-safety exit hardware, where a substituted spring rate can change how the push bar behaves.
4) Do I need to replace the whole exit device, or can I just swap the spring?
For a failed return spring, just the spring. The 651F948 is a field-serviceable replacement part, so a technician can restore ED4000 or ED5000 operation in place instead of buying a complete device. If the latch, chassis, or rods are also damaged, that is a separate repair.
5) Is this Corbin Russwin exit device spring suitable for a high-traffic commercial opening?
Yes, it is a commercial-grade part. The 651F948 is classified for commercial rather than residential use and is the spring used in ED4000 and ED5000 devices on schools, hospitals, offices, retail, warehouses, government buildings, and multi-tenant residential entries.
