Falcon A08790-000 626 – Frequently Asked Questions

1) What does a mortise cylinder collar actually do, and do I need one?
A collar is the spacer ring that sits between the face of the mortise cylinder and the escutcheon or trim. The Falcon A08790-000 is a straight protective collar: it fills the gap so the cylinder sits flush with the trim, covers the cylinder threads, and keeps the cylinder from being gripped or wrenched. You need one whenever the cylinder body sits deeper than the trim opening, which is common when a cylinder length and a door thickness do not line up exactly.
2) How do I pick the right thickness of Falcon A08790-000 collar?
It comes in five thicknesses: 9/32 inch, 13/32 inch, 17/32 inch, 21/32 inch and 55/64 inch. Measure how far the cylinder face stands proud of, or sinks below, the escutcheon face and choose the collar that brings the cylinder flush. Cylinders are sold in 1/8 inch length increments, so the collar is what takes up the remainder once you have the closest cylinder length.
3) Will a straight collar work with my knob or lever rose, or is it only for escutcheon trim?
The A08790-000 is specified for escutcheon trim on Falcon mortise lock assemblies. Escutcheon plates carry a cylinder hole in the plate itself, and the straight (non-tapered) profile is what seats correctly in that flat opening. If your trim is a round rose or a sectional design with a recessed or beveled cylinder opening, a straight collar will not sit flush and you want the tapered collar sized for that trim instead.
4) Does the Falcon A08790-000 include the mortise cylinder?
No. It is the collar only. You order the mortise cylinder separately in the keyway and length your system uses. For a Grade 1 mortise cylinder we also carry the Corbin Russwin 1000 Series in 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 Series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Match the cam to what your Falcon mortise lock body requires.
5) I need a mortise cylinder for an escutcheon trim job, not a spacer ring. Which part should I be ordering?
The Falcon A08790-000 is a straight protective mortise cylinder collar - the ring that sits between the cylinder face and the escutcheon trim, not the keyed cylinder itself. If the cylinder is what you need, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the Corbin Russwin 1000 is a Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam. Order the collar alongside whichever cylinder you choose when the trim leaves a gap at the cylinder face.
6) Will a mortise cylinder collar work on a rim cylinder opening?
No. The Falcon A08790-000 collar is built for mortise cylinder assemblies behind escutcheon trim, where the threaded cylinder body screws into the lock case. Rim cylinders mount through the door with a tailpiece and use a different backing arrangement - examples include the Schlage 20-021 six-pin rim cylinder with vertical tailpiece cam, the Schlage 20-022 with horizontal tailpiece cam, and the Corbin Russwin 3070 six-pin rim cylinder housing with a 1-7/8 inch tailpiece. For a rim device, specify the cylinder and its own trim ring rather than a mortise collar.
7) What finishes does the Falcon A08790-000 collar come in, and can I match my existing trim?
Five finishes: 605 bright brass, 606 satin brass, 613 oil-rubbed satin bronze, 625 bright chrome and 626 satin chrome. Every one of those is offered in all five collar thicknesses, so you are not forced to compromise on appearance to get the depth you need. 626 satin chrome is the usual match for standard commercial satin chrome lever trim.
8) I am converting a Falcon mortise lock to interchangeable core. Do I still need this collar?
Yes, if the new cylinder still sits below the escutcheon face. The collar is independent of the keying system, so it works the same whether you fit a conventional mortise cylinder or an LFIC housing. On an interchangeable core conversion the housing length often changes, so recheck the gap and pick the collar thickness from the five offered (9/32, 13/32, 17/32, 21/32, 55/64 inch). For the core side we carry BEST 1C Series 5-pin cores and the BEST 1CB 150 Series interchangeable core cylinder.
9) Can I use this collar on an aluminum storefront door with a deadlock?
Not the right part for that. The A08790-000 is for escutcheon trim on Falcon mortise lock assemblies in a swinging commercial door. Narrow stile aluminum storefront with an Adams Rite deadlock takes a cylinder pull or dedicated mortise cylinder instead: the Adams Rite 4024 and 4025 cylinder pulls are made for the MS1847 deadlock and deadlatch, the 4026 for the 5017 wood door deadlock, and the Adams Rite 4036 mortise cylinder is a Grade 1 unit for a 1/2 inch minimum door thickness.
10) We are standardizing on interchangeable core keying. Does a collar like the Falcon A08790-000 still apply, or do we need different parts?
The collar is a trim component and is independent of your keying program - the A08790-000 straight protective collar addresses the space between the cylinder and the escutcheon on Falcon mortise assemblies. The keying decision sits with the cylinder: the Corbin Russwin 1080 is a 1-1/2 inch six-pin LFIC mortise cylinder with an A01 cam, the Schlage 20-057 is a six-pin FSIC rim cylinder with convertible tailpiece cam, and the BEST 1CB is a 150 Series interchangeable core cylinder. Choose the core platform first, then add the collar if the trim requires it.
11) The door has a cylinder pull rather than escutcheon trim. Is the Falcon collar the right part?
No. The A08790-000 is sized and shaped to finish a mortise cylinder at escutcheon trim. Cylinder pull applications use a dedicated pull assembly instead: the Adams Rite 4024 cylinder pull includes trim plate mounting for MS1847 deadlock and deadlatch systems, the 4025 is a five-pin tumbler cylinder pull with through-screws for the same MS1847, and the 4026 five-pin tumbler pull is for wood door applications with the Adams Rite 5017 wood door deadlock or deadlatch.
12) Is this a residential part or rated for high-traffic commercial doors?
Commercial. The collar is intended for commercial door hardware installations, which is why it shows up on office buildings, schools, hospitals, retail, warehouses, multi-tenant residential and government facilities. It is a Falcon replacement part, so maintenance teams servicing an existing mortise lock get the original fit and finish rather than a generic ring.
13) I am standardizing collars across a building. Can I order one thickness in quantity for all doors?
Only if the doors are genuinely identical. Collar thickness is set by the difference between cylinder length and trim depth at each opening, so a building with mixed door thicknesses or mixed cylinder lengths will need more than one. The practical approach is to survey the openings, group them, then order the matching thickness from the five offered, all in one finish so the doors look consistent.
14) Is the Falcon A08790-000 a substitute for a dummy cylinder where no keying is needed?
They do different jobs. The A08790-000 is a protective collar that shields the cylinder installation and finishes the transition at the escutcheon. Where an opening needs the look of a cylinder with no operating function, a dummy is the part to specify - the BEST 12E Series dummy rim cylinder is offered with a 1-5/32 inch diameter. A collar can be used together with an operating or dummy cylinder, but it will not fill an empty cylinder hole on its own.
15) Can I use this Falcon collar when retrofitting a knob or lever cylinder?
The A08790-000 is a mortise cylinder collar for escutcheon trim on commercial mortise lock assemblies, so it is not the trim part for a key-in-knob or key-in-lever retrofit. For those, the cylinder is the item to order: Kaba Ilco offers the 1539 Series key-in-knob and lever universal cylinder, the 1579 Series knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder.
