Kaba Ilco 7120-DC-26D – Frequently Asked Questions

1) What is a dummy mortise cylinder actually for?
A dummy mortise cylinder is a non-keyed filler. The Kaba Ilco dummy is listed as non-keyed with a dummy lock function, so there are no pins and no key, and it will not operate a lock. It threads into a mortise cylinder hole to close it off and give a matching cylinder face where no locking is wanted, on the inactive leaf of a pair, on a push-pull storefront door, or where a cylinder was removed and the prep is still open. If you need the door to actually lock, you want a keyed mortise cylinder instead.
2) Will the Kaba Ilco dummy mortise cylinder fill my existing cylinder hole?
It is a mortise cylinder, so it threads into a standard mortise cylinder prep, the same threaded hole a keyed mortise cylinder screws into. Match the length to how deep the hole is and how far the cylinder needs to sit proud of the face. The Ilco dummy runs from 3/4 inch through 2 inch in 3/4, 1, 1-1/8, 1-1/4, 1-5/16, 1-3/8, 1-1/2, 1-5/8, 1-3/4, 1-7/8 and 2 inch, so measure the cylinder you pulled out and order the same length.
3) What length dummy mortise cylinder do I need for a 1-3/4 inch storefront door?
Length here is the cylinder body, not the door. Pull the cylinder that is in the door now, measure it, and buy the matching size out of the 3/4 to 2 inch range. On a 1-3/4 inch door, the common pulls are 1-1/8 and 1-1/4 inch, both of which the Ilco dummy offers, but the mortise housing depth and how much the cylinder must project through the trim decide it, not the door thickness alone.
4) Can I key a dummy mortise cylinder later if I change my mind?
No. The Ilco dummy is built non-keyed with a dummy function, so there is no pin stack, no plug to key and no keyway to pin up. A locksmith cannot convert it. If the opening might need to lock down the road, buy a keyed mortise cylinder now, for example the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch with an A02 straight cam, and keep the dummy for the openings that will stay non-locking.
5) What is the difference between an Ilco dummy mortise cylinder and a keyed mortise cylinder like the Corbin Russwin 1000?
The Ilco dummy mortise cylinder is non-keyed with a dummy lock function, so it fills the cylinder hole and presents a finished face without operating anything. The Corbin Russwin 1000 is a Grade 1 series mortise cylinder supplied in a 1-1/2 inch length with an A02 straight cam, so it turns a cam that drives the lock body. Choose the Ilco dummy where the opening needs the appearance of a cylinder on an inactive leaf or a pull-side face, and the Corbin Russwin 1000 where the cylinder actually has to retract or throw a bolt.
6) What should I use on an aluminum storefront door if I need the cylinder to actually operate the deadlock rather than just look like one?
The Ilco dummy mortise cylinder is non-keyed and will not operate a lock. For an Adams Rite MS1847 deadlock or deadlatch, the Adams Rite 4024 cylinder pull mounts with a trim plate, and the 4025 is a five pin tumbler cylinder pull that mounts with through-screws. On a wood door with an Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part. If the prep simply needs a working mortise cylinder, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security and a 1/2 inch minimum door thickness.
7) I need a working mortise cylinder in a Schlage C keyway, not a dummy. What is the comparable part?
The Ilco dummy mortise cylinders are non-keyed. Where the same mortise prep needs a keyed cylinder in a Schlage C keyway, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in Schlage C keyway. The Ilco dummy range covers lengths from 3/4 inch through 2 inch, so a 1-1/8 inch dummy is the direct dimensional counterpart if some openings in the same run only need the hole filled.
8) A rim cylinder and a dummy mortise cylinder look similar in a photo. How do I tell which one my exit device needs?
They are not interchangeable. The Ilco dummy cylinders are mortise type and non-keyed. Schlage rim cylinders for exit devices come with a specific tailpiece cam orientation: the 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and two keys. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. If the device is driven by a tailpiece through the door, it needs a rim cylinder, not a mortise dummy.
9) I need the dummy to match the keyed cylinders already on my building. What finishes are there?
Eleven finishes cover the usual commercial palette: Bright Brass, Satin Brass, Antique Brass, Satin Bronze, Oil Rubbed Bronze, Satin Nickel, Bright Chrome, Satin Chrome, Black Aluminum, Bright Stainless Steel and Satin Stainless Steel. For a property manager standardizing a floor of doors, satin chrome (626) and oil rubbed bronze are the two that most often match existing commercial trim. Pick the finish off the cylinder face beside it, not off the lever, since lever and cylinder finishes are not always the same on an older opening.
10) My storefront door has an Adams Rite deadlatch and an empty cylinder hole. Can I use a dummy cylinder there?
Only if you want that hole permanently non-functional. A dummy has no plug and no cam, so it cannot retract an Adams Rite latch. To make the opening work again you need a keyed mortise cylinder cut for that lock, like the Adams Rite 4036 five-pin mortise cylinder, or a cylinder pull such as the 4025 with through-screws or the 4024 with trim plate mounting, both for the MS1847 deadlock. Use the Ilco dummy on the leaf you are blanking off, not on the operating one.
11) We use interchangeable cores across the facility. Does a dummy mortise cylinder work with that system?
It sits outside the system. The Ilco dummy is a fixed non-keyed housing, so it takes no core and belongs to no keying system. For openings that do need to be on the IC system, a core-accepting product is the part to spec, such as the BEST 1CB 150 Series interchangeable core cylinder or the Schlage 20-057 six-pin FSIC rim cylinder with convertible tailpiece cam. Use the dummy only where the opening will never be keyed.
12) Can a BEST interchangeable core be used where an Ilco dummy mortise cylinder is specified?
They serve different purposes. The Ilco dummy mortise cylinder is a non-keyed replacement part with a dummy function. The BEST 1C Series standard 5-pin cylinder core and the BEST Peaks 1CB 150 Series interchangeable core cylinder are keyed core products, and the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass, 150 Series. Use an Ilco dummy where the hole needs filling and no key operation is wanted, and a BEST core where the opening is part of an interchangeable core keying system.
13) We are standardizing a building on interchangeable cores. Where do dummy mortise cylinders still fit, and what handles the keyed openings?
Dummy mortise cylinders cover the openings that need a finished cylinder face but no key: they are non-keyed replacement parts with a dummy function, offered in eleven finishes including Satin Chrome, Oil Rubbed Bronze and Satin Stainless Steel so the inactive leaves match the keyed ones. For the keyed side of the same program, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is a full size interchangeable core cylinder in C keyway with a 643E Aged Bronze finish. The Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam.
14) What cam options do the mortise cylinder alternatives use if a straight cam does not clear my lock body?
The Ilco dummy mortise cylinder is non-keyed and drives nothing, so cam choice does not apply to it. Among keyed mortise cylinders, the Corbin Russwin 1000 in 1-1/2 inch length uses an A02 straight cam, while the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Confirm which cam profile the lock body accepts before ordering the keyed cylinder.
15) Can I put a dummy mortise cylinder in a residential handleset or deadbolt?
The Ilco dummy mortise cylinders are commercial mortise parts and non-keyed. Handlesets and deadbolts generally take rim type cylinders instead: the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 is a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit cylinder for an Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and Emtek's own CY4 cylinder is sold each.
16) Is a key-in-lever cylinder the same thing as a mortise cylinder?
No. The Ilco dummy is a mortise type cylinder that threads into a mortise cylinder hole. The Falcon A23161-05 G is a key in lever cylinder from the RU/T Series with a 6-pin G keyway, keyed different, supplied with two cut keys, and it fits the lever chassis rather than a mortise prep. Identify whether the door carries a mortise lock body or a cylindrical lever lock before ordering either.
17) Which mortise cylinder alternative carries a Grade 1 rating?
Among the mortise cylinders, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, the Corbin Russwin 1000 is a Grade 1 series mortise cylinder, and the Corbin Russwin 1070 is a Grade 1 series 1-1/4 inch 6-pin mortise housing. The Ilco dummy mortise cylinder sits alongside these as the non-keyed part for openings in the same run that need a matching cylinder face without key operation.
18) Is this rated for commercial use or is it a residential part?
Commercial. The Ilco dummy mortise cylinder is classified as a commercial part and is a replacement part in the Ilco brass mortise cylinder line, the same brass housing family as their keyed mortise cylinders. That is what makes it a reasonable fit on storefront, office and multi-family openings where the face has to look like the rest of the hardware.
19) Does the Kaba Ilco dummy mortise cylinder come with a cam or trim ring?
It is sold as the cylinder itself, a non-keyed mortise body in your chosen length and finish. A dummy does not use a cam, since there is nothing turning. If the existing prep is oversized or chewed up and the cylinder face will not cover it, plan on a collar or ring separately.
