Dormakaba DORC300-PA-LS-62 – Frequently Asked Questions

1) Will the Dormakaba C300 work on a 2 inch thick door?
No. The C300 tops out at 1-3/4 inches of door thickness. For a 2 inch door, the Cal-Royal CAL20 privacy and CAL30 passage Calypso locksets are rated 1-3/8 to 2 inches, and the Lockey 1600 and 2830 keyless knob locks cover 1-1/8 to 2 inches. Confirm the function you need is offered in whichever of those you choose.
2) I'm replacing an old cylindrical lockset in an apartment. Will the C300 cover the existing holes?
In most cases yes. The C300 is a bored cylindrical lockset that fits doors prepped with 4 inch or 5-1/2 inch hole centers, which covers the standard commercial cylindrical prep and the wider spacing used on some existing doors. Measure center to center from the main cross bore to the through-bolt or lower hole before you order. If the old lock was a mortise lock rather than a bored one, the C300 will not drop into that pocket.
3) Does the Dormakaba C300 latch into my existing strike, and which strike should I order?
The latch throws 1/2 inch, which is standard for a cylindrical lockset, so it will engage a normal cylindrical strike pocket as long as the door and frame gap is within spec. Five strikes are offered so you can match what is already cut into your frame: 5001 ANSI square corner, 5101 T strike square corner, 5102 T strike radius corner, 5201 full lip square corner, and 5202 full lip radius corner. Radius versus square matters if you are reusing an existing frame cutout, so check the corners of the current strike before choosing.
4) Is the Dormakaba C300 rated for a fire door?
A UL listed 3 hour fire rating is available on the C300 as an option, so it can be specified for a rated opening. It is also ANSI/BHMA A156.2 Grade 2 certified and meets A117.1 accessibility code and ADA requirements for barrier-free accessibility, which is what most institutional and multifamily specs ask for on a corridor or unit entry door.
5) Is a Grade 2 lock like the Dormakaba C300 enough for an apartment building, or should I be buying Grade 1?
Grade 2 is the right call for light duty, price sensitive commercial openings, which is exactly what the C300 is built for: apartment units, condominiums, hotels, assisted living, and similar multifamily housing. For a high traffic opening, a school corridor, or an entry that takes constant abuse, step up to a Grade 1 cylindrical lockset such as the Marks USA 195 Survivor Series entry lever or the Cal-Royal CAL20 and CAL30 Calypso Series, which are extra heavy duty Grade 1. Note the Cal-Royal units cover 1-3/8 to 2 inch doors, a slightly wider thickness range than the C300.
6) Which function of the Dormakaba C300 do I order for a bedroom versus a unit entry door?
Five functions are offered on the C300: Entrance, Passage/Hall/Closet, Patio, Privacy/Bed/Bath, and Single Dummy Trim. Privacy/Bed/Bath is the push button bed and bath lock, Passage is unlocked both sides for a hall or closet, Entrance is the keyed unit entry, Patio locks from inside only, and Single Dummy Trim is a fixed lever with no latch for an inactive leaf. Order one per opening by what the door does, not by what matches visually, since all five share the same lever styles and finishes.
7) Can I get all the Dormakaba C300 locks in my building keyed alike?
Keying is selected at no charge when ordering, either keyed different or keyed alike, on the SC keyway. Keyed alike gets one key operating every C300 you order on that request, which is what a property manager wants for a maintenance or common area set. Keyed different gives each unit its own key.
8) What do I have to specify when ordering a Dormakaba C300 lockset?
Four things are required on every C300 order: backset (2-3/8 or 2-3/4 inches), strike (5001 ANSI square corner, 5101 or 5102 T strike, 5201 or 5202 full lip), handing (RH or LH), and keying (keyed different or keyed alike, free). On top of that you choose function, lever style, and finish. Backset and strike are the two that get orders sent back, so measure the existing bore to the door edge and look at the frame cutout before you commit.
9) I need a keypad lock instead of a keyed lever on an apartment door - what replaces the Dormakaba C300?
The C300 is a mechanical key-operated cylindrical lockset on an SC keyway. For pushbutton entry on the same cylindrical prep, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a digital keypad, 100 user codes, and IC/SFIC compatibility, for doors 1-5/8 inch to 1-7/8 inch thick. The Alarm Lock Trilogy 4100 is the privacy-function equivalent over the same thickness range, and the DL5200 is double-sided with 100 user capacity. All three run on batteries rather than a keyed cylinder, so keying a building alike is replaced by code management.
10) What is a Grade 1 alternative to the Dormakaba C300 lever lock for a higher-traffic opening?
The C300 is an ANSI/BHMA A156.2 Grade 2 certified cylindrical lever lockset built for light-duty commercial use such as apartments, condominiums, hotels, and assisted living. When the opening calls for Grade 1, the Cal-Royal Calypso series covers the same core functions in a Grade 1 extra heavy duty cylindrical lockset: the CAL30 is the passage version and the CAL20 is the privacy version, both fitting doors 1-3/8 inch to 2 inch thick. The Marks USA Survivor series is another Grade 1 route, with the 195N passage lever listed as ADA compliant and the 195RAB clutched entry lever supplied less core.
11) Which Grade 2 cylindrical lockset lines up function for function with the Dormakaba C300?
The Orca Hardware OCL series is the closest function-for-function Grade 2 medium duty match. The C300 covers Entrance, Passage/Hall/Closet, Patio, Privacy/Bed/Bath, and Single Dummy Trim; Orca splits those across separate part numbers - OCL250 for entrance, OCL210 for passage, OCL240 for privacy, and OCL2170 for a half dummy lever. Marks USA also fields Grade 2 cylindrical trim, with the 175RF storeroom clutched lever prepped for a small format interchangeable core on a 2-3/4 inch backset with an ANSI strike. Note the C300 uses an SC keyway rather than an IC prep.
12) My doors are 1-3/8 inch thick - which cylindrical locksets besides the Dormakaba C300 will fit?
The C300 fits doors 1-3/8 inch through 1-3/4 inch, which covers older multifamily and interior doors. Among cylindrical peers, the Cal-Royal CAL20 privacy and CAL30 passage both cover 1-3/8 inch to 2 inch, and the Lockey E985 and E995 keypad lever locks cover 1-3/8 inch to 1-3/4 inch. Most of the electronic cylindrical options start at 1-3/4 inch, including the TownSteel XCE-2000 and XCE-9000 at 1-3/4 inch to 2 inch and the SDC Electra 7200 at 1-3/4 inch to 2 inch, so those will not land on a 1-3/8 inch door.
13) Is a knob lockset an acceptable substitute for the Dormakaba C300 lever?
Not where barrier-free access is required. The C300 lever meets A117.1 accessibility code and ADA requirements, and its lever comes in LCB, LGB, LRB, and LSB styles. The Marks USA 110AB is a Grade 2 entry lockset with a round knob on a 2-3/8 inch backset in satin stainless steel, and the Lockey 1600 and 2830 are keyless knob locks - knob trim, which does not satisfy the same barrier-free operation requirement. If a knob is acceptable on the opening, those work; if the door is on an accessible route, stay on a lever such as the C300 or the Marks USA 195N Grade 1 ADA compliant passage lever.
14) The C300 is for light duty multifamily - what should I use on a school classroom door instead?
The C300 is an economy Grade 2 lever lockset aimed at apartments, condominiums, assisted living, and other light duty commercial facilities, and it does not carry a classroom function. For classroom openings, the TownSteel FCE-2000 is a Grade 1 heavy duty standalone motorized cylindrical lockset with RFID on 1-3/4 inch doors, the FCE-4000 adds the RFID intruder classroom function on the same thickness, and the XCE-9000 is a keypad classroom intruder lockset for 1-3/4 inch to 2 inch doors. The Schlage XE360M is a Grade 1 wireless tubular lock with a classroom/storeroom function and a smart mobile reader for 1-3/4 inch doors.
15) Can I use a Kwikset SmartCode 912TNL in place of the Dormakaba C300 on an apartment entry?
They solve different problems. The C300 is an ANSI/BHMA A156.2 Grade 2 certified commercial lockset with an optional UL listed 3 hour fire rating and a 2-1/2 inch diameter rose, offered in 605 bright brass, 619 satin nickel, 626 satin chrome, and 690 dark bronze. The Kwikset 912TNL ZW500 is a SmartCode electronic Tustin lever with Z-Wave, keyed one side, for doors 1-3/8 inch to 2 inch - it brings remote control and code entry, and it is not carrying the commercial grade certification or fire rating the C300 does. For a unit door on a rated opening in a commercial building, the C300 is the one that meets the spec.
16) Do I need to specify handing on the Dormakaba C300, or is it non-handed?
The lockset itself is non-handed, so installation does not change for a left or right hand door. The exception is the LS lever style, which is handed. Handing is still selected when ordering, so give the door hand if you are speccing the LS lever.
17) What finishes and lever styles does the Dormakaba C300 come in, and will it match my existing hardware?
Four finishes are offered: 605 Bright Brass, 619 Satin Nickel, 626 Satin Chrome, and 690 Dark Bronze. Lever styles are LCB, LGB, LRB, and LSB. The rose is 2-1/2 inches in diameter with concealed fasteners, so no exposed screws show on the face. If you are matching existing openings, 626 Satin Chrome is the usual commercial standard and the rose diameter is what decides whether the new lock covers the wear ring left by the old one.
18) What is the closest alternative to the Dormakaba C300 if I want a similar keyed cylindrical lockset from another brand?
Two close ones. The Stanley Security QCL200 is a cylindrical lock also supplied keyed different on the SC keyway, with a 118F ANSI 1-1/8 x 2-3/4 inch strike, so the keyway matches if you are already standardized on SC. The Orca Hardware OCL250 is a Grade 2 medium duty entrance cylindrical lockset, and Orca also offers the OCL210 passage, OCL240 privacy, and OCL2170 half dummy so you can cover a whole unit from one series the way the C300 functions do.
19) How does the Dormakaba C300 compare to the Stanley QCL200 and QCL150?
The Dormakaba C300 and the Stanley Security QCL200 are both cylindrical locksets supplied keyed different on an SC keyway; the QCL200 ships with a 118F ANSI 1-1/8 inch by 2-3/4 inch strike, while the C300 lets you pick the strike at order time from ANSI square corner, T strike in square or radius corner, and full lip in square or radius corner. The Stanley QCL150 is a Grade 2 entry lever with a Sierra bent lever, supplied less cylinder on a square 2-3/4 inch backset latch with a 4-7/8 inch by 1-1/4 inch ASA strike - so it arrives without a core, where the C300 comes keyed with free keyed alike or keyed different keying.
20) What is the difference between the Dormakaba C300 and an access control lock like the Schlage NDEB or SDC Electra 7200?
The C300 is a standalone mechanical lockset - keyed cylinder, SC keyway, no power at the door. The Schlage NDEB is a Grade 1 ENGAGE series heavy duty cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader and mobile-enabled multi-function operation for doors 1-5/8 inch to 2 inch. The SDC Electra 7200 is a solenoid controlled cylindrical lock running dual voltage 12/24VDC for 1-3/4 inch to 2 inch doors, which means wiring to the opening and a power supply. Choosing either of those turns a hardware swap into an access control job; the C300 replaces like for like with a key.
21) I need an interchangeable core lock for a master keyed building - is the Dormakaba C300 the right choice?
The C300 is built around an SC keyway cylinder and ships keyed alike or keyed different. If the building standard is small format interchangeable core so cores can be rotated without pulling the lock, the Marks USA 175RF is a Grade 2 storeroom clutched lever with SFIC prep supplied less core on a 2-3/4 inch backset with an ANSI strike, and the Marks USA 195RAB is a Grade 1 Survivor entry clutched lever, also less core. On the electronic side, the Alarm Lock DL2700 is IC/SFIC compatible and the BEST 9KZ EZ series keypad cylindrical lock has a key override function.
22) What is a simpler non-keyed alternative to the Dormakaba C300 for a closet or corridor door?
The C300 covers Passage/Hall/Closet and Single Dummy Trim alongside its keyed functions, so a non-keyed opening can stay on the same series and match the levers on the rest of the doors. If you are buying the non-keyed openings separately, the Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset and the OCL2170 is a Grade 2 half dummy lever. For a Grade 1 passage lever, the Cal-Royal CAL30 covers 1-3/8 inch to 2 inch doors and the Marks USA 195N is an ADA compliant Survivor series passage lever.
23) Which privacy lock should I put on a bathroom door if I am not using the Dormakaba C300?
The C300 offers a Privacy/Bed/Bath function in the same series, so it keeps the bathroom door matching the unit's other levers. Alternatives at other grades: the Orca Hardware OCL240 is a Grade 2 medium duty privacy cylindrical lockset, and the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock for doors 1-3/8 inch to 2 inch. If the privacy door needs to be electronic, the Alarm Lock Trilogy 4100 is a Grade 1 electronic cylindrical lock with privacy function and keypad for 1-5/8 inch to 1-7/8 inch doors, and the Schlage CO-100 is a Grade 1 heavy duty standalone keypad lock with privacy function for 1-3/4 inch doors.
