Arrow 16CR-123-1 26D – Frequently Asked Questions

1) What thicknesses do Arrow cylinder spacer rings come in, and how do I pick one?
Three thicknesses: 1/8 inch, 1/4 inch and 3/8 inch. Pick by how far the cylinder is sitting proud of, or sunk into, the trim or lock face. Measure the gap you need to close and choose the ring that brings the cylinder flush with the correct cam engagement; where the gap falls between sizes, rings can be combined (1/8 plus 1/4 gives 3/8). Buying one of each size is common practice for a service truck.
2) Will this spacer ring fit a Schlage or Corbin Russwin mortise cylinder, or is it Arrow only?
The 16CR-123-1 is an Arrow part made for Arrow cylinder assemblies. Treat it as Arrow-specific. If you are shimming a different brand's cylinder, order the spacer or collar from that brand's parts line instead, since thread diameter and collar profile differ between makers. For reference, cylinders like the Schlage Commercial 20-021 rim cylinder or the Corbin Russwin 1000 Series Grade 1 mortise cylinder are separate systems with their own trim rings.
3) Is the Arrow 16CR-123-1 spacer ring a replacement cylinder, or do I still need a cylinder?
The Arrow 16CR-123-1 is a cylinder spacer ring - a shim that sets the cylinder's depth and alignment in the lock body, not a keyed cylinder. If the cylinder itself is what you are replacing, you need an actual cylinder such as the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, the Schlage Commercial 20-021 six-pin rim cylinder with a vertical tailpiece cam, or the Detex MC65 mortise cylinder with a Schlage C keyway. The 16CR-123-1 comes in 1/8 inch, 1/4 inch and 3/8 inch thicknesses to bring whichever cylinder you use flush to the trim.
4) Which finishes can I get the Arrow 16CR-123-1 spacer ring in to match my existing door hardware?
Six finishes, all standard BHMA numbers: 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed, 625 Bright Chrome and 626 Satin Chrome. Because the ring is visible at the cylinder face, match it to the cylinder collar and trim, not to the door. Every one of the six is offered in all three thicknesses, so finish does not limit your size choice.
5) My Arrow cylinder turns but the latch does not retract. Is a spacer ring the fix?
Often yes. If the cylinder sits too deep or too shallow, the cam or tailpiece never fully picks up the lock mechanism, and the key turns without throwing the bolt. Adding or changing the 16CR-123-1 spacer ring resets the cylinder depth so the cam engages. Rule out a broken tailpiece or a worn cam first, because a spacer only corrects depth, not damaged parts.
6) Can I use a stack of spacer rings to move an Arrow cylinder out on a thicker door?
That is the normal use. A thicker door or added trim, plate, or armor plate pushes the lock face out relative to the cylinder, and the ring takes up the resulting gap. With 1/8, 1/4 and 3/8 inch available you can build up in 1/8 inch steps. If you need more projection than the rings can give, the correct answer is a longer cylinder rather than a taller stack of spacers, since an over-shimmed cylinder loses thread engagement and can work loose.
7) Does the 16CR-123-1 come with a cylinder or keys?
No. It is the spacer ring on its own, a replacement component for an Arrow cylinder assembly. You supply the cylinder and keys. If you need the cylinder itself, that is a separate order, and for Arrow JL interconnected locks the Medeco 1065140 5-pin retrofit cylinder is one option ZenSupply carries.
8) We want to standardize on interchangeable core - is a spacer ring like the Arrow 16CR-123-1 still the right direction?
A spacer ring such as the Arrow 16CR-123-1 supports keeping existing Arrow mechanical lock cylinders in service in commercial openings. If the goal is a keying program built on interchangeable cores instead, the hardware to look at is core-based: the BEST 1CB Peaks 150 Series interchangeable core cylinder, the BEST 1CDF drill-resistant patented seven-pin brass interchangeable core, the BEST 1C five-pin standard core, or the Schlage 20-057 six-pin FSIC rim cylinder with a convertible tailpiece cam. Those change the keying platform; the 16CR-123-1 only addresses cylinder depth and alignment.
9) My cylinder sits too deep in an aluminum storefront deadlock - does the Arrow 16CR-123-1 fix that?
The Arrow 16CR-123-1 spacer ring is intended for Arrow mechanical lock cylinder assemblies, adjusting how the cylinder seats, and is offered in 1/8, 1/4 and 3/8 inch. Adams Rite deadlock openings are handled differently: the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, the 4025 five-pin cylinder pull uses through-screws for the same MS1847, and the 4026 five-pin cylinder pull is for the 5017 wood door deadlock. For the cylinder itself on those doors, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness.
10) What if the lock I am servicing is a key-in-knob or key-in-lever rather than an Arrow cylinder needing a spacer?
Key-in-knob and key-in-lever bodies take their own replacement cylinders: the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T six-pin G keyway, keyed different with two cut keys. The Arrow 16CR-123-1 is a spacer ring for Arrow cylinder assemblies and does not substitute for any of those.
11) I need a non-keyed filler for an unused cylinder hole - is the Arrow 16CR-123-1 what I want?
No. The Arrow 16CR-123-1 is a spacer ring that sets cylinder depth behind the trim, in 1/8, 1/4 or 3/8 inch and finishes including 605 bright brass, 626 satin chrome and 613 satin bronze oil-rubbed. For a non-functioning fill at a rim prep, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the item built for that purpose.
12) Is the Arrow 16CR-123-1 spacer ring suitable for institutional facilities standardized on Arrow locks?
It is classed as commercial hardware and is the part schools, hospitals, municipal buildings and multi-tenant properties stock to service installed Arrow mechanical lock cylinders. Because it is an Arrow OEM component, it keeps serviced openings on the same parts standard as the rest of the Arrow hardware in the building. Ordering it in one facility-standard finish across all three thicknesses keeps a maintenance shop covered for most cylinder depth corrections.
13) Does a mortise housing like the Corbin Russwin 1070 include the spacer the Arrow 16CR-123-1 provides?
The Corbin Russwin 1070 is a Grade 1 series 1-1/4 inch six-pin mortise housing with an A01 cloverleaf cam, and the 1080 is a 1-1/2 inch LFIC six-pin mortise cylinder for Schlage L9000 mortise locks with an A01 cam - those are cylinder bodies sold by their own length. The Arrow 16CR-123-1 is a separate ring used with Arrow cylinder assemblies to take up the remaining gap when cylinder length and door or trim thickness do not match exactly, and comes in 1/8, 1/4 and 3/8 inch.
