Schlage C604-144 – Frequently Asked Questions
1) What does the Schlage C604-144 spring actually do inside a hotel function lock?
The C604-144 is the spring behind the indicator pin on a Schlage hotel function lock. It returns the indicator pin so the visual occupancy signal actuates properly. If the indicator on a guest room lock has stopped popping out or stopped returning, this spring is the part that restores that motion rather than the whole lock.
2) Which Schlage lock series does the C604-144 indicator pin spring fit?
It fits the Schlage A, AL, CL, D, F, H, ND, PL, S and S200 Series lock families. That covers the common commercial cylindrical and knob/lever lines, so one part number covers hotel function locks across most of a Schlage-standardized building.
3) Can I repair a Schlage hotel function lock instead of replacing the whole lockset?
Yes, when the fault is the indicator pin. The C604-144 is a genuine Schlage replacement spring built to OEM tolerances for a drop-in fit, so a locksmith or maintenance tech can rebuild the indicator mechanism and leave the existing lock body, cylinder and keying in place. Full lock replacement is only needed if the chassis or cylinder itself is damaged.
4) Is the C604-144 spring suitable for high-traffic commercial doors or is it a residential part?
Commercial. The C604-144 is classified as a commercial part and is intended for the high-cycle demands of hospitality, office and institutional openings, which is where hotel function locks are used in the first place. Typical uses include hotel guest rooms, healthcare, schools, multi-tenant residential and government buildings.
5) Should I stock the Schlage C604-144 for a Corbin Russwin lock?
No. The C604-144 is a Schlage part matched to Schlage A, AL, CL, D, F, H, ND, PL, S and S200 lock geometry, and springs and pins are not cross-brand items. For Corbin Russwin hardware the equivalent small-parts item we carry is the Corbin Russwin Swivel Spindle Pin X Set Screw, which is listed for 1-3/4 inch door thickness. Order by the lock's own brand.
6) How do I order the right Schlage indicator pin spring for a fleet of guest room locks?
Order by the part number C604-144. It is a single-SKU item with no finish or size options to specify, and because it covers the A, AL, CL, D, F, H, ND, PL, S and S200 families you can standardize one line item across mixed Schlage hotel function locks in the same property.
7) I need a spindle part rather than an indicator spring - what should I order?
If the failure is in the spindle rather than the indicator pin, the Corbin Russwin swivel spindle pin with set screw is the spindle-side part, listed for 1-3/4 inch doors. The Schlage C604-144 addresses only the hotel function indicator pin, and it is a genuine Schlage replacement part for the A, AL, CL, D, F, H, ND, PL, S and S200 Series. Match the part to the lock brand on the door: the C604-144 is a Schlage component, the swivel spindle pin is Corbin Russwin.
8) Is the C604-144 a genuine Schlage part or an aftermarket copy?
Genuine Schlage OEM, manufactured to original Schlage specifications so it seats without filing, bending or shimming. That matters on a spring: an out-of-tolerance aftermarket spring will either fail to return the indicator pin or bind it.
