Schlage C604-051 – Frequently Asked Questions

1) What exactly is the Schlage C604-051 and what does it do?
The C604-051 is a screw post, a small OEM Schlage replacement component used in Corbin Wood Products mailbox cylinder assemblies. It is a hardware part, not a cylinder or a lock, so it does not come keyed and it will not secure a mailbox door on its own. Order it when the existing post in the assembly is stripped, lost, or damaged and the rest of the cylinder is still good.
2) Will the Schlage C604-051 screw post fit any mailbox lock, or only certain ones?
Only Corbin Wood Products mailbox applications. Schlage builds the C604-051 specifically for those cylinder assemblies, so it is a like-for-like swap there and nothing else is claimed for it. If your mailbox bank is another make, this post is the wrong part, and a generic screw post from the bin is a gamble on thread and length.
3) Is the Schlage C604-051 screw post a substitute for a mailbox cylinder itself?
No. The C604-051 is a Schlage replacement screw post used within Corbin Wood Products mailbox cylinder assemblies, so it restores the mounting hardware rather than the keyed cylinder. If the cylinder itself needs replacing, a complete cylinder is the part to order - for example the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, or the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter where no keyed function is needed.
4) We need a keyed mortise cylinder for a commercial door, not a mailbox part - what should we look at instead of the Schlage C604-051?
The C604-051 is a commercial replacement screw post for Corbin Wood Products mailbox applications, so it will not serve a mortise lock opening. For mortise cylinders, the Corbin Russwin 1000 Grade 1 series comes in a 1-1/2 inch length with an A02 straight cam, the Corbin Russwin 1070 Grade 1 series offers a 1-1/4 inch 6-pin housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
5) Will the Schlage C604-051 work in an aluminum storefront or wood door deadlock?
No - the C604-051 is built specifically for Corbin Wood Products mailbox cylinder assemblies. For storefront and entry door deadlock hardware, the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both made for the Adams Rite MS1847 deadlock/deadlatch, while the Adams Rite 4026 five pin tumbler cylinder pull is made for the 5017 wood door deadlock/deadlatch. The Adams Rite 4036 mortise cylinder is a Grade 1 five-pin unit with a 1/2 inch minimum door thickness.
6) Is this a commercial-duty part for apartment and office mailbox banks?
Yes, it is classed as a commercial part and the intended uses are multi-tenant installations: apartment and condo common area mailboxes, office mail centers, hotel guest mailbox stations, schools, and municipal mail facilities. Property managers maintaining a bank of Corbin Wood Products boxes can stock it as a routine MRO spare.
7) Do I need to modify or re-drill the mailbox to install the C604-051?
No. It is built to the original component's specifications as a direct like-for-like replacement, so it restores function without modification to the existing hardware. Swap the old post out and the new one in with the cylinder assembly it belongs to.
8) My mailbox cylinder itself is worn out, not just the screw post. What should I be looking at instead?
A screw post will not fix a failing plug or worn pins. If the cylinder is the problem you need a replacement cylinder, not a mounting part. For general commercial cylinder swaps, options include the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1539 key-in-knob/lever universal cylinder, or a Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, depending on what housing you are feeding. Match the cylinder style and tailpiece to the assembly you are servicing.
9) If we want to bring mailbox or cabinet cylinders onto our master key system instead of replacing a screw post, what are the options?
The C604-051 is a mechanical replacement part with no keying of its own. To standardize keying you would change the cylinder: the BEST 1CB is a 150 series interchangeable core cylinder, the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass in the 150 series, and the BEST 1C is a standard 5-pin cylinder core. Interchangeable cores let a facility rekey by swapping the core rather than the housing.
10) Are the Kaba Ilco 1539 and 1599 cylinders interchangeable with the Schlage C604-051?
They are not. The C604-051 is a screw post for Corbin Wood Products mailbox cylinder assemblies, while the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1579 is a knob and lever cylinder for Sargent locks. Those are keyed cylinder replacements for lockset bodies, not mailbox mounting hardware.
11) For a residential handleset or deadbolt retrofit, is the Schlage C604-051 the right part?
No - the C604-051 is a commercial-rated Schlage replacement part for Corbin Wood Products mailbox applications. For handleset and deadbolt retrofits, Medeco offers the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1065244 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Emtek CY4 cylinder is also sold individually.
12) We use Schlage L9000 mortise locks - does the Schlage C604-051 relate to those, and what cylinder fits them?
The C604-051 is a mailbox screw post replacement part and has no role in an L9000 mortise lock. The cylinder made for that application in the comparable set is the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, listed for Schlage L9000 mortise locks with an A01 Schlage L cam.
13) Does the Schlage C604-051 come keyed or with keys?
No keys are involved. The C604-051 is a screw post, a mechanical mounting component within the cylinder assembly, so there is no keyway, no pinning, and nothing to key alike. Keying stays with whatever cylinder is already in the mailbox door.
14) Is the C604-051 a genuine Schlage part or an aftermarket copy?
It is OEM Schlage, manufactured to Schlage's own standards for the Corbin Wood Products mailbox assembly. For a locksmith or facilities crew standardizing on genuine parts across a mailbox bank, that means fit and thread match the component being pulled out.
15) Is there a Schlage keyway cylinder option if we are standardizing a mailbox bank on Schlage keys?
The C604-051 itself is a Schlage screw post and carries no keyway. Where a Schlage-keyed cylinder is needed, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series 6-pin G keyway supplied keyed different with two cut keys.
