Arrow AR18 – Frequently Asked Questions
1) What exactly is the Arrow AR18, and is it a cylinder or just a part of one?
The AR18 is a cam only, not a cylinder. It is an Adams Rite style screw-on cam that mounts to the back of a compatible Arrow mortise cylinder to drive the lock. If you need a complete keyed cylinder rather than the cam, order the cylinder itself, for example the Adams Rite 4036 Grade 1 mortise cylinder.
2) Is the Arrow AR18 cam a substitute for a complete mortise cylinder?
No. The AR18 is an Adams Rite screw-on cam, a replacement part that attaches to the back of a cylinder to drive the lock. If the cylinder body itself is worn or you need a complete keyed unit, a full mortise cylinder is the item to order instead, such as the Adams Rite 4036 mortise cylinder with five-pin security, or the Corbin Russwin 1000 Grade 1 series mortise cylinder in 1-1/2 inch length with an A02 straight cam. Those arrive as complete cylinders; the AR18 is the cam alone.
3) I have a rim device, not a mortise lock. Does the Arrow AR18 work, or do I need a different part?
Rim exit devices are driven by a tailpiece rather than an Adams Rite screw-on cam, so the AR18 is not the part for that opening. Rim cylinders to look at include the Schlage 20-021 six-pin rim cylinder with a vertical tailpiece cam, the Schlage 20-022 six-pin rim cylinder with a horizontal tailpiece cam, and the Corbin Russwin 3070 six-pin rim cylinder housing with a 1-7/8 inch tailpiece. Confirm which tailpiece orientation your device requires before ordering.
4) What should I order if I need a different cam style than the Adams Rite pattern on the Arrow AR18?
The AR18 is cut to Adams Rite cam geometry, so it only suits cylinders and locks expecting that pattern. For a cloverleaf cam application, the Corbin Russwin 1070 Grade 1 series 1-1/4 inch six-pin mortise housing is supplied with an A01 cloverleaf cam, and the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC six-pin cylinder for Schlage L9000 mortise locks uses an A01 cloverleaf cam. For a straight cam, the Corbin Russwin 1000 series 1-1/2 inch mortise cylinder carries an A02 straight cam.
5) Why would I replace the cam instead of the whole cylinder?
A stripped, bent or wrong-geometry cam is a common reason a mortise cylinder turns but fails to throw the bolt. Swapping the AR18 cam restores that function without pulling and rekeying a full cylinder assembly, so the existing keying in the building stays intact.
6) Does the Arrow AR18 come with keys or a cylinder body?
No keys and no cylinder body. It ships as a replacement cam component only. If you want a keyed assembly out of the box, a cylinder such as the Falcon A23161-05 G, which comes keyed different with two cut keys, is the kind of item to order instead.
7) We key our building on interchangeable cores. Does an Arrow AR18 cam fit into that program, or is there a better route?
The AR18 is a screw-on cam for conventional cylinder assemblies and does not itself provide an interchangeable core. Facilities standardizing on removable cores generally specify a core-based product instead, such as the BEST 1CB 150 series interchangeable core cylinder, the BEST 1CDF drill resistant patented seven-pin brass interchangeable core in the 150 series, or the Schlage 20-057 six-pin FSIC rim cylinder with convertible tailpiece cam. Those let maintenance rekey by swapping the core rather than servicing cam hardware.
8) My Adams Rite MS1847 deadlock needs service. Is the Arrow AR18 the right part?
The AR18 is an Adams Rite style screw-on cam for cylinder assemblies, not trim for the deadlock. If what you need is the cylinder pull at the door, the Adams Rite 4024 cylinder pull with trim plate mounting and the Adams Rite 4025 five pin tumbler cylinder pull with through-screws are both designed for use with the Adams Rite MS1847 deadlock and deadlatch. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock and deadlatch.
9) Can the Arrow AR18 cam be used to fix a key-in-knob or key-in-lever lock?
No. Key-in-knob and key-in-lever locks take a purpose-built plug cylinder rather than a screw-on Adams Rite cam. For those openings, the Kaba Ilco 1539 series key-in-knob and lever universal cylinder or the Kaba Ilco 1599 key-in-knob replacement cylinder are the correct replacements, and the Kaba Ilco 1579 knob and lever cylinder is made for Sargent locks. The Falcon A23161-05 G key in lever cylinder covers the RU/T series with a six-pin G keyway, keyed different with two cut keys.
10) Is the Arrow AR18 cam an Arrow-specific part, or can I use it across other manufacturers' cylinders?
The AR18 is a genuine Arrow replacement component intended for Arrow cylinder product lines that call for an Adams Rite style cam. Other brands supply their own cam or tailpiece with the cylinder rather than as a loose Arrow part - for example the Medeco 1065244 five-pin rim lazy motion cylinder comes with an Emtek tailpiece, and the Medeco 1065140 five-pin retrofit cylinder is built for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. Match the cam to the cylinder family you are servicing.
11) Is the AR18 cam suitable for high traffic commercial doors?
Yes, it is a commercial rated part. The screw-on attachment is what matters in heavy use: it is fastened rather than pressed, so it resists working loose on doors cycled all day in offices, schools, healthcare and multi-tenant buildings.
12) Can maintenance staff install the AR18 cam, or does it need a locksmith?
It is written for trade use. The cylinder has to come out of the lock and the cam has to be oriented and screwed on correctly for the bolt to throw, so it is work for a locksmith, door hardware installer, or a maintenance tech who has done cylinder swaps before.
13) We need a non-keyed filler in an opening. Would the Arrow AR18 work for that?
No. The AR18 is a functional cam that drives a lock from a working cylinder, so it has no role in a blank opening. Where a cylinder body is needed for appearance or to fill a prep without keying, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the appropriate item.
