Kaba Ilco 45-1-3-04-26D-5 – Frequently Asked Questions
1) Will the Kaba Ilco 4500 deadbolt fit my door, and what bore does it need?
The 4500 Series mortise cylinder deadbolt installs on wood or metal doors of any thickness. Prep is a 1-7/8 to 2-1/8 inch cross bore (47.3mm to 54mm) with a standard 1 inch (25.4mm) edge bore, which is the same cross bore range a standard tubular deadbolt prep already gives you. Backset is your choice of 2 inch, 2-3/8 inch, or 2-3/4 inch, so it drops onto an existing hole at either of the two common commercial backsets or at the 2 inch used on narrower stiles.
2) Can I use my own mortise cylinder in the Ilco 4500 deadbolt?
Yes. The 4500 accepts a standard US thread mortise cylinder and works with either a Lori fan shaped cam or an Adams Rite cam. It can be ordered less cylinder if you are keying it into an existing system with cylinders you already stock, or with a standard keyed cylinder supplied.
3) Should I order the single cylinder, double cylinder, or classroom function 4500 deadbolt?
Three functions are offered on the 4500. Single cylinder is key outside, ADA turn lever inside, and its handing is field reversible so one part covers both hands. Double cylinder is keyed both sides, which is what you use on a glass door or a door with a lite next to the lock where a turn lever could be reached from outside; check your local egress code before specifying it. Classroom function locks and unlocks by key only, so a room can be secured from the corridor side without keying the occupant.
4) What keyway can I get the Ilco 4500 deadbolt in so it works on my existing master key system?
Keyways cover most of the systems you would find in a commercial building: Arrow AA, Corbin CA/CB/CC/CD, Corbin Russwin CE, Russwin RA and RB, Sargent GA/GB/GC, Schlage C, E, F, SX and Everest EA/EB, Yale YA and YG, Kwikset KS, Weiser WA and WE, Lockwood LA, Segal FA, Dominion DA, Lori UB/UD/UE, Ilco UA, and composite NA/NB. Cylinders come 5 or 6 pin, and keying is available keyed different or keyed alike. Note the Lori 90 keyway (UD) is 6 pin only and Lori 80 (UE) is 5 pin.
5) What else do I have to specify to order a 4500 deadbolt complete?
Five decisions make the part. Function (single cylinder, double cylinder, or classroom), finish, bolt (2 inch backset with 1 inch front, 2-3/8 inch backset with 1 inch front, 2-3/4 inch backset with 1-1/8 inch front, or no bolt if you are reusing one), strike (regular duty or heavy duty), and cylinder (less cylinder, or a keyed cylinder with keyway, 5 or 6 pin, cylinder length, and keyed alike or keyed different). Bolts are available drive in or screw in.
6) I need a deadbolt for an aluminum storefront door with a narrow stile. Is the Ilco 4500 the right choice?
The 2 inch backset bolt is what makes the 4500 usable where a 2-3/8 or 2-3/4 inch backset will not fit the stile, and it takes a standard US thread mortise cylinder with an Adams Rite cam, which is the cam storefront hardware normally uses. Confirm your stile depth against the 2 inch backset plus the 1-7/8 to 2-1/8 inch cross bore before you drill. If the stile is too narrow for any bored prep, you are looking at a different type of lock entirely, not this one.
7) Which deadbolt should I use for a classroom function opening instead of the Kaba Ilco 4500?
The Falcon D111 is a Grade 1 heavy duty classroom deadbolt in the D100 Series with an adjustable backset and cylinder x thumbturn operation. The Falcon D211 is the Grade 2 medium duty classroom function version with single cylinder operation, and the Hager 3118 is a Grade 1 classroom deadbolt supplied with a Schlage C keyway and a 6-pin cylinder for 1-3/8 to 1-3/4 inch doors. The Kaba Ilco 4500 also offers a classroom function, and it takes a standard US thread mortise cylinder in keyways including Schlage C, Sargent LA, Corbin, Yale 8 and Russwin, so it is the one to pick when the classroom opening has to key into an existing system that is not Schlage C.
8) What is the closest heavy duty alternative to the Kaba Ilco 4500 deadbolt for a 1-3/4 inch commercial door?
The Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock in the DL3000 Series with a door thickness range of 1-3/4 to 2-1/4 inches, and the DL3211 is a Grade 1 cylindrical deadlock rated for 1-3/4 inch doors. Both are keyed cylinder x blank rather than cylinder x turn, so the inside face is plain. The 4500 is a mortise cylinder deadbolt that installs on wood or metal doors of any thickness and is offered in single cylinder, double cylinder and classroom functions, so if you need a thumbturn inside, stay with the 4500 single cylinder; if the inside face must be blank on a 1-3/4 inch door, the DL3011 or DL3211 covers it.
9) I need an SFIC or interchangeable core deadbolt - is the Kaba Ilco 4500 the right choice?
The Kaba Ilco 4500 takes a standard US thread mortise cylinder and operates with a Lori fan shaped or Adams Rite cam, so it is built around a threaded mortise cylinder rather than a small format core. For an SFIC opening, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core for 1-3/8 to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 single deadbolt with a 2-3/4 inch backset prepped for an interchangeable core. The Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D. Order the 4500 less cylinder only if you are supplying your own mortise cylinder, not a core.
10) Which deadbolt should I standardize on across a facility if I need a fire rated option?
The Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt with a Schlage C keyway and a fire rating, the Hager 3215 is a Grade 2 commercial single cylinder deadbolt with a 1 inch throw and a fire rating, and both cover 1-3/8 to 1-3/4 inch doors. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Kaba Ilco 4500 is the one to standardize on when the fleet runs mixed keyways, since it takes a mortise cylinder in Schlage C, Schlage Everest, Sargent LA, Corbin, Russwin, Yale 8, Weiser, Kwikset and Lori profiles, keyed alike or keyed different.
11) What Grade 1 single cylinder deadbolts compare to the Kaba Ilco 4500?
The Accentra D111 is a Grade 1 single cylinder deadbolt in the D Series with a 2-3/8 inch backset and cylinder x thumbturn function for 1-3/8 to 1-3/4 inch doors. The Dexter DB1000 single cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. The Kaba Ilco 4500 single cylinder differs in that its handing is field reversible and its backset is chosen at order time from 2 inch with a 1 inch front, 2-3/8 inch with a 1 inch front, or 2-3/4 inch with a 1-1/8 inch front, rather than fixed at 2-3/8 inch.
12) Do I need to worry about handing when ordering an Ilco 4500 deadbolt?
Not on the single cylinder version. Its handing is field reversible, so the same lock handles a left or right hand door and you can stock one part number across a building. Double cylinder is keyed both sides, so there is no turn to orient.
13) Which strike should I order with the Ilco 4500, regular duty or heavy duty?
Both are offered. Regular duty suits an interior or low traffic opening where the frame does the work. Heavy duty is the one to spec on an exterior entry, a hollow metal frame taking abuse, or any opening in a building where forced entry is a concern. If you are replacing a bolt only and the existing strike is sound, you can order the deadbolt with no bolt and keep the strike prep you have.
14) How is the Ilco 4500 different from a standard residential-style deadbolt like the Dexter DB1000 or Arrow DBX61?
The 4500 is a mortise cylinder deadbolt, meaning the cylinder is a separate threaded mortise cylinder you choose the keyway and pinning for, and it installs on wood or metal doors of any thickness. Conventional single cylinder deadbolts are built around a fixed cylinder and a stated door range: the Dexter DB1000 is listed at 1-3/8 to 1-3/4 inch, the Dexter DB2000 at 1-3/8 to 1-3/4 inch, and the Arrow DBX61 is a Grade 2 cylinder x thumbturn. Pick the 4500 when you need a specific keyway to match a master key system or a door outside the usual thickness range; pick a fixed-cylinder deadbolt when you just need a standard entry lock.
15) Can I get several Ilco 4500 deadbolts keyed alike across a building?
Keyed alike and keyed different are both offered on the 4500, so a set of units, a row of storage rooms, or a fleet of exterior doors can run on one key. Pick a single keyway across the order and the whole group operates together. If you already run a master key system, order the keyway that matches it (Schlage C, Sargent LA, Yale 8, Corbin, Russwin and others are available) rather than starting a second key system.
16) Does the Ilco 4500 deadbolt meet ADA for the inside turn?
The single cylinder 4500 is available with an ADA turn lever on the inside, which gives a lever shape that can be operated without tight grasping or twisting. Double cylinder and classroom versions are key operated on both sides, so if ADA egress operation matters on your opening, the single cylinder with the ADA turn lever is the one to order.
17) Can I use an electronic deadbolt in place of the Kaba Ilco 4500?
Only if you are changing how the door is credentialed. The Codelocks CL2210 is an electronic mortise deadbolt and the CL2200 is a medium duty electronic surface deadbolt in brushed steel. The Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override, and the Nova-D is an RFID multihousing smart electronic deadbolt. The DynaLock 1300 Series is a heavy duty mortise electric deadbolt driven by an access control system rather than a credential at the door. The Kaba Ilco 4500 stays fully mechanical on a standard mortise cylinder, which is what keeps it on the same key system as the rest of the building.
18) What is a simpler double cylinder deadbolt than the Kaba Ilco 4500 for a standard 1-3/4 inch door?
The Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors. The Dexter DB1000 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 to 1-3/4 inch doors, and the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for 1-3/8 to 1-3/4 inch doors. Each of those arrives as a fixed package. The Kaba Ilco 4500 double cylinder is specified piece by piece - backset of 2 inch, 2-3/8 inch or 2-3/4 inch, regular or heavy duty strike, and with or without cylinder - which is what you want when the opening is nonstandard rather than a common 1-3/4 inch door.
19) Is the Arrow 460 strike a substitute for the strike that comes with the Kaba Ilco 4500?
No. The Arrow 460 is a mortise lock strike for latchbolt x deadbolt functions with a straight lip, sized for a 1-3/4 inch door - it is a strike plate on its own, not a lock. The Kaba Ilco 4500 is the deadbolt itself and is ordered with either a regular duty or a heavy duty strike as part of the lock, along with the bolt and backset. Buy the Arrow 460 only when you are replacing a damaged strike in an existing mortise lock frame prep.
20) What deadbolt works for an exit only door where no key is needed on the inside?
The Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on one side and a thumbturn on the other, for 1-3/8 to 1-3/4 inch doors. The Callan Model 205S is a Grade 3 one sided half-bore deadbolt, which only bores one face of the door. The Kaba Ilco 4500 in single cylinder form has a key outside and a turn inside with field reversible handing, and is also offered with an ADA turn lever, so it is the choice when the door still has to be keyed from outside.
21) What is the difference between the Kaba Ilco 4500 and the Dormakaba M1960 or D900 deadbolts?
The Dormakaba M1960 is an M1000 Series single cylinder deadbolt, cylinder by turn, supplied with no trim. The Dormakaba D900 is a small case mortise deadbolt with a D cylinder, keyed different with SC keyways. The Kaba Ilco 4500 covers single cylinder, double cylinder and classroom functions on one platform, with 2 inch, 2-3/8 inch and 2-3/4 inch backsets and drive in or screw in bolts, so it spans a wider set of preps than a fixed small case or trimless unit.
22) What is a lighter duty single cylinder deadbolt than the Kaba Ilco 4500 for interior or low traffic doors?
The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn on the same door thickness range. The Callan Model 200S is a Grade 3 single cylinder square trim deadbolt. Stepping up, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard and the Arrow DBX61 is a Grade 2 single cylinder deadbolt. The Kaba Ilco 4500 is built for professional installation on wood or metal doors of any thickness with a heavy duty or regular duty strike, so it suits openings the Grade 3 units are not sized for.
23) I need a deadbolt combined with a latch or lever - what should I look at instead of the Kaba Ilco 4500?
The Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, which puts the deadbolt and the latch on one prep. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, in square and round trim. The Kaba Ilco 4500 is a deadbolt alone with its own bolt and strike, so the door needs a separate latch or a push-pull if it also has to stay closed against the stop.
24) What finishes does the Kaba Ilco 4500 deadbolt come in for matching other doors?
Eight finishes are orderable: antique brass, bright brass permanent, bright chrome, oil-rubbed bronze, satin brass, satin bronze, satin chrome, and satin stainless steel. Satin chrome and satin stainless are the usual matches for commercial openings already fitted with 626 or 630 hardware; oil-rubbed bronze and antique brass are the ones to pick when you are matching older decorative trim in a lobby or residential entry.
25) Is a Baldwin or Emtek decorative deadbolt an alternative to the Kaba Ilco 4500?
They solve a different problem. The Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in the Estate Series, and the Baldwin Reserve line includes contemporary round and square double cylinder deadbolts. Emtek offers the 8323 Modern Disc double cylinder deadbolt in brass and the #11 Tuscany lost wax cast bronze deadbolt with cylinder x thumbturn. Those are trim-driven residential and architectural products. The Kaba Ilco 4500 is a commercial deadbolt offered in eight finishes including satin stainless steel, satin chrome and oil-rubbed bronze, chosen to match commercial door hardware rather than residential trim suites.
