Kaba Ilco Mortise Tumbturn Cylinders for Commercial Thumb Turn Locks (10-Pack)

It's a mortise cylinder with a thumbturn knob instead of a key plug, so the door is unlocked by twisting rather than keying. The Ilco ADA Turn Knob replaces the inside cylinder on a commercial mortise lock where you want no key required to get out or to unlock from the secure side. Body threads and cam mount are the same as a keyed mortise cylinder, so it drops into the same mortise cylinder hole.

Yes, that's the usual reason to buy it. On an Adams Rite style double cylinder deadlock you swap the inside keyed cylinder for the turnknob so occupants can exit without hunting for a key, and keep the keyed cylinder outside. Order the Adams Rite cam for that lock. Check your local egress code before converting, since some jurisdictions restrict thumbturns on required exit doors.

No. This is a thumbturn, not a keyed plug, so there's nothing to key or master. If you need the opening keyed into a system, use a keyed mortise cylinder instead: the Corbin Russwin 1000 Series Grade 1 mortise cylinder in 1-1/2 inch with an A02 straight cam, or the 1070 Series 6-pin housing in 1-1/4 inch with an A01 cloverleaf cam, and for a Schlage L9000 mortise lock the Corbin Russwin 1080 LFIC in 1-1/2 inch.

Depends on what the lock is. A mortise cylinder threads into the lock body and turns a cam, which is what the Ilco turnknob is. A rim cylinder mounts through the door and drives a tailpiece into a surface mounted device such as a rim exit device: for that you'd want a Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal one. Look at the back of the existing part. Threaded barrel with a flat cam means mortise; two mounting screws and a flat bar tailpiece means rim.

The Ilco ADA turn knob mortise cylinder is a mortise-body part operated by a knob rather than a key, so if the opening needs key control on that side, look at the Corbin Russwin 1000 Grade 1 series mortise cylinder in 1-1/2 inch length with an A02 straight cam, or the Corbin Russwin 1070 Grade 1 series 6-pin mortise housing in 1-1/4 inch with an A01 cloverleaf cam. Both are keyed mortise cylinders in the same mortise-threaded format the Ilco turn knob uses, so the prep in the lock body does not change; only the way the cylinder is operated does.

The Ilco ADA turn knob mortise cylinder is available with an Adams Rite cam or a standard cam, which covers Adams Rite style mortise prep. But if the hardware is an Adams Rite MS1847 deadlock or deadlatch and you want a cylinder pull rather than a mortise turn knob, 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 built specifically for the MS1847 deadlock and deadlatch. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock and deadlatch instead.

No. The Ilco ADA turn knob is a mortise cylinder, threaded into a mortise lock body, while rim cylinders mount through the door and drive an exit device or rim lock with a tailpiece. Parts such as the Schlage 20-021 rim cylinder with a vertical tailpiece cam, the Schlage 20-022 with a horizontal tailpiece cam, and the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece all take rim prep, not mortise threads. If the door has a mortise lock, a rim cylinder will not thread in regardless of finish or length.

The Ilco ADA turn knob mortise cylinder is a fixed mortise part operated by a knob, so it does not accept a removable core. For an interchangeable core program, the Corbin Russwin 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder is a 6-pin large format interchangeable core mortise cylinder with an A01 Schlage L cam for Schlage L9000 mortise locks. On the small format side, the BEST 1CB Peaks 150 series interchangeable core cylinder, the BEST 1CDF drill resistant patented 7-pin brass 150 series core, and the BEST 1C standard 5-pin cylinder core all supply the core itself for a keyed-core system.

Three finishes: bright brass (03), oil rubbed bronze (10B), and satin chrome (26D). Satin chrome 26D is the usual match for aluminum storefront and commercial lever hardware; 10B suits dark bronze storefront framing. All three are available across the length and cam range, so a property manager standardizing a building can hold one finish and vary only the length.

It ships as a 10-pack, one cam and one length and one finish per pack. That suits a locksmith stocking a truck or a facility converting a run of doors to thumbturn at once. If you need a single mortise cylinder for one opening, a per-piece option like the Emtek CY4 cylinder is sold each.

The shortest option is 15/16 inch, which is what narrow aluminum stile locks generally need. Ilco's mortise cylinder line runs 15/16 up to 2 inches, so measure the depth from the cylinder collar seat to the lock case before ordering. If your opening uses an Adams Rite MS1847 deadlock and you want a pull rather than a cylinder in the stile, the Adams Rite 4024 cylinder pull with trim plate mounting or the 4025 with through-screws is built for that lock.

Replacement part only. The Ilco ADA turnknob is the cylinder that goes into a commercial mortise lock you already have. It does not include the lock body, trim, strike, or mounting screws. If the lock case itself is worn out, the cylinder won't fix it.

Yes, provided the lock takes a standard threaded mortise cylinder and you order the standard cam rather than the Adams Rite cam. Match the length to how deep the cylinder hole sits behind the trim. For a wood door running an Adams Rite 5017 deadlock instead, the Adams Rite 4026 five pin cylinder pull is the part made for that lock.

The Ilco ADA turn knob mortise cylinder is a commercial part sold for mortise locks. Where a submittal calls for a graded mortise cylinder, the Adams Rite 4036 mortise cylinder with five-pin security is Grade 1 in the 4036 series and fits doors from 1/2 inch minimum thickness. The Corbin Russwin 1000, 1070 and 1080 series mortise cylinders are also Grade 1 series parts. Those are keyed cylinders rather than turn knobs, so specify the operation you need on each side of the opening.

The Ilco ADA turn knob mortise cylinder is knob-operated, so there is no keyway to match. For a keyed mortise cylinder on a Schlage C keyway, the Detex MC65 mortise cylinder is a 1-1/8 inch 6-pin commercial grade cylinder in the Schlage C keyway. Pair it with the Ilco turn knob on the opposite side of the opening when the door needs key outside and thumb turn inside.

No. The Ilco ADA turn knob is a commercial mortise cylinder for mortise locks and does not fit handleset and deadbolt cylinder pockets. Those take rim-type retrofit cylinders instead: the Medeco 1012040 6-pin lazy motion rim cylinder is built for Kwikset single cylinder deadbolts, the Medeco 1075127 5-pin lazy motion single cylinder is for handlesets and deadbolts, the Medeco 1065244 5-pin lazy motion rim cylinder carries an Emtek tailpiece, and the Medeco 1065140 5-pin retrofit cylinder covers the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder.

The Ilco ADA turn knob mortise cylinder is a fixed mortise-format part and will not accept a full size interchangeable core. For an FSIC program on rim-prepped hardware, the Schlage 20-057 6-pin FSIC rim cylinder with a convertible tailpiece cam covers the housing, and the Schlage 20-057-C full size interchangeable core cylinder is supplied in the C keyway with a 643E aged bronze finish. Both are rim format, so the door prep differs from the mortise threads the Ilco turn knob uses.

The Ilco ADA turn knob mortise cylinder is a working part that operates the mortise lock. Where an inactive leaf or a blank position only needs matching hardware with no operation behind it, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills a rim prep as a dummy. It is a rim-format part, so it does not thread into mortise prep the way the Ilco turn knob does.

The Ilco ADA turn knob mortise cylinder comes in bright brass, oil rubbed bronze and satin chrome across ten lengths from 15/16 inch up to 2 inch, which is why it standardizes well across a building. If the function has to change to a keyed cylinder, the Corbin Russwin 1000 series in 1-1/2 inch and the 1070 series in 1-1/4 inch fall inside that same length band, and the Schlage 20-057-C is offered in 643E aged bronze. Confirm the finish call-out on the order, since a keyed cylinder and a turn knob will sit side by side on the same opening.
