Corbin Russwin 312F25-8 – Frequently Asked Questions

1) Will a 312F25-8 spindle work in a CK4200 lock that is not dormitory function?
No. The 312F25-8 is the dormitory function dogging spindle. Dormitory function locks behave differently from storeroom, classroom or entry functions, and the spindle is part of what produces that behavior, so ordering it for a different CK4200 function will not give you the operation you want. Match the spindle to the function of the lock you are repairing.
2) Is the 312F25-8 an OEM Corbin Russwin part or an aftermarket spindle?
It is the Corbin Russwin factory part, model 312F25-8, sold as a replacement component for CK4200 cylindrical locksets. For a facility standardized on Corbin Russwin, using the OEM spindle keeps the chassis operating as it was built rather than mixing in a generic part.
3) Can I rebuild a dorm room lock with just this spindle, or do I need the whole lockset?
If the chassis and trim are sound and the fault is in the spindle, the 312F25-8 is a component-level repair for the CK4200 dormitory function lock. It is a spindle only, so knobs, levers, roses, cylinders and the chassis itself are separate orders. Facilities running large numbers of dorm openings usually stock these to avoid replacing complete locksets.
4) Is the Corbin Russwin 312F25-8 spindle suitable for commercial and institutional buildings?
Yes, it is a commercial-duty part. Corbin Russwin lists the 312F25-8 as commercial rather than residential hardware, and the dormitory function it supports is what you find in university housing, multi-tenant residential, hospitality and healthcare openings.
5) What does dormitory function mean on a CK4200 lock this spindle goes into?
Dormitory function is the lock behavior the 312F25-8 spindle supports on a CK4200 cylindrical lockset: the outside lever or knob is locked or unlocked by key, and the inside always allows free egress. It is specified for student housing and similar multi-occupancy rooms where the occupant controls locking from inside and staff key from the corridor.
