DORMA C150 Series Locks

The C100 Series Grade 1 heavy-duty cylindrical locksets provide exceptional security, enhanced aesthetics, and rugged dependability.

ANSI F109 Entry Function: Deadlocking latch bolt operated by trim from either side, except when outside trim locked by push button inside. Key outside releases push button, unlocking outside trim, except when inside button pushed and turned to keep outside trim locked. Operating inside trim releases push button, unlocking outside trim, except when inside button pushed and turned to keep outside trim locked. Inside button must be turned to unlock outside trim. Inside trim always operates latch bolt.

Exceptionally smooth operation: To ensure exceptionally smooth operation, the C100 Series locks with lever trim incorporate a cast stainless steel retractor combined with roller bearings. This design provides both extremely high strength and an extended service life for the lock mechanism.

Easy installation: C100 Series locksets are easy to install in both wood and hollow metal doors with ANSI/BHMA Standard A156.115 preparations for cylindrical locks.

Freewheeling function: All C100 Series operating lever trim features a specially designed freewheeling function to protect the lock from damage caused by excessive torque applied to the lever handles. When locked, the outside lever handle will move freely through a 60° arc without operating the latch bolt. This free movement minimizes the opportunity for damage to the lock mechanism.

Finish: 626 satin chrome

Lever: “R” Rectangular lever design – ADA compliant with 1/2″ return

Rose Design: C or E (stepped design)

Dormakaba C150 D LRC 626 – Frequently Asked Questions

1) Will the Dorma C150 drop into my existing lock prep and strike cutout?
It bores 2-3/4 inch backset and ships with the 10252 latch, 1-1/8 x 2-1/4 inch front, 1 inch diameter bolt, square corner. The strike is the 5001-1316 ANSI strike with dustbox, 1-1/4 x 4-7/8 inches, 1-3/16 inch lip, square corner. If your frame already has a 4-7/8 inch ANSI strike cutout and a 2-3/4 inch backset bore, it goes straight in. The C100 Series is prepped to ANSI/BHMA A156.115, which is the standard cylindrical lock prep for wood and hollow metal doors.
2) What does the entry/office function on the Dorma C150 actually do at the door?
Push button inside locks the outside lever. A key outside releases the button and unlocks the outside lever. Turning the inside button holds the outside lever locked even after someone uses the inside lever. The inside lever always retracts the deadlocking latch bolt, so you are never locked in. It is the ANSI F109 entry function, catalogued under ANSI/BHMA F82.
3) Can I order the Dorma C150 less core for my own small format interchangeable core system?
Yes. Three cylinder choices: D conventional cylinder with SC keyway and two keys, J for SFIC less core, and L conventional less core. If you key your own building on SFIC, order the J and drop your cores in. Note it is a single cylinder lock, so the key is on the outside only.
4) Is there a keyless or keypad version of the Dorma C150 entry function?
The C150 is a mechanical keyed lock with a conventional or SFIC cylinder. If you want code entry on the same cylindrical prep, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical entrance 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 Schlage NDEB is a Grade 1 heavy duty wireless cylindrical lock with Bluetooth Low Energy and storeroom, office, privacy and apartment functions for 1-5/8 inch to 2 inch doors. Note both cover a narrower door thickness band than the C150's 1-3/8 inch to 2-1/4 inch.
5) What is the closest Grade 1 keyed entry lever lock to the Dorma C150 from another manufacturer?
The Marks USA 195RAB is the nearest match: it is a Grade 1 entry/office clutched lever lockset from the Survivor Series, supplied less core with an American lever. The Dorma C150 is also a Grade 1 entry/office cylindrical lever lock, and it can be ordered less core as well through its L conventional cylinder or J SFIC options, or keyed with a D conventional SC keyway cylinder and two keys. Both give you a clutched or freewheeling lever that turns without retracting the latch when locked.
6) The opening is a restroom, not an office. What should I use instead of the Dorma C150?
The C150 is a keyed entry/office lock with a single cylinder, which is not a restroom function. For privacy, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock covering 1-3/8 inch to 2 inch doors, and the Orca OCL240 is a Grade 2 medium duty privacy cylindrical lockset. For a closet or corridor door that needs no locking at all, the Marks USA 195N is a Grade 1 ADA compliant passage lever and the Cal-Royal CAL30 is a Grade 1 passage lock.
7) Is the Marks USA 110AB a substitute for the Dorma C150?
It shares the entrance/office function but differs in three ways that matter. The 110AB is a Grade 2 round knob lockset on a 2-3/8 inch backset in satin stainless steel. The Dorma C150 is Grade 1 with an ADA compliant lever on a 2-3/4 inch backset, offered in LC, LG and LR lever styles and eight finishes from 605 bright brass through 626 satin chrome. If the door needs lever operation for ADA or the frame is prepped for a 2-3/4 inch backset, the 110AB is not a drop-in.
8) Do I have to specify handing when ordering the Dorma C150 lever lock?
Handing comes down to the lever you pick, not the chassis. Choose from LC, LG, or LR levers, and the hand follows that selection. Give the door hand when you order so the lever points the right way.
9) What finishes does the Dorma C150 come in if I need to match existing hardware across a building?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, and 626 satin chrome. 626 satin chrome is the usual commercial standard if you are standardizing corridors. Rose is either C at 3-1/2 inch diameter or the E stepped rose.
10) Is the Dorma C150 lever ADA compliant for a public building?
The R rectangular lever design is ADA compliant with a 1/2 inch return. Levers rather than knobs are what ADA-governed openings require, and the C150 is a lever lock throughout.
11) Will the Dorma C150 hold up on a high-traffic tenant or office door?
It is a Grade 1 heavy-duty commercial cylindrical lockset. The lever trim uses a cast stainless steel retractor with roller bearings, and the outside lever freewheels through a 60 degree arc when locked so somebody yanking on it does not break the chassis. That freewheeling feature is the main reason these survive apartment and office corridors.
12) Is the Dorma C150 a Grade 1 lock or a Grade 2 like the cheaper entry levers?
Grade 1, the heavy-duty commercial tier. Several common entry levers sit a grade below it: the Stanley QCL100 Series entry lever and the Orca OCL250 entrance lockset are both Grade 2, and the Marks USA 110AB entry knob is Grade 2 as well. If your spec sheet calls for Grade 1 on tenant or corridor doors, those are not substitutes.
13) Can the Dorma C150 go into a wood door as well as a hollow metal frame door?
Both. C100 Series locksets install in wood and hollow metal doors using the standard ANSI/BHMA A156.115 cylindrical prep, so a mill-prepped wood door or a factory-prepped hollow metal leaf takes it without extra machining.
14) If I do not need Grade 1 on an interior office door, what is a lighter-duty keyed entry lever instead of the Dorma C150?
The Stanley Security QCL150 is a Grade 2 entrance lever with a Sierra bent lever and rose, supplied less cylinder, with a square 2-3/4 inch backset latch and a 4-7/8 inch by 1-1/4 inch ASA strike. That matches the Dorma C150's 2-3/4 inch backset and its 5001-1316 ANSI strike at 1-1/4 inch by 4-7/8 inch, so the door and frame prep is the same. The Orca OCL250 is another keyed entrance cylindrical lockset at Grade 2 medium duty.
15) I need a storeroom function rather than entry/office. What replaces the Dorma C150?
The C150 is an entry/office lock where the inside push button controls the outside lever. If you need the outside lever locked at all times with key access only, the Marks USA 175RF is a Grade 2 storeroom clutched lever lockset with small format IC, less core, and a 2-3/4 inch backset with an ANSI strike, which matches the C150's 2-3/4 inch backset prep.
16) My door is 1-3/8 inch thick. Which locks besides the Dorma C150 will fit?
The Dorma C150 covers 1-3/8 inch to 2-1/4 inch, the widest band of the comparable group. Among peers, the Cal-Royal CAL20 privacy and CAL30 passage locks both cover 1-3/8 inch to 2 inch, and the Lockey 1600 and 2830 keyless knob locks cover 1-1/8 inch to 2 inch. Most of the electronic options, such as the TownSteel XCE-2000 at 1-3/4 inch to 2 inch and the Alarm Lock DL5200 at 1-5/8 inch to 1-7/8 inch, start above 1-3/8 inch.
17) For a classroom or school door, should I specify the Dorma C150 or something else?
The C150 is an entry/office function, so the outside lever is controlled by the inside push button rather than by a classroom-specific sequence. For classroom openings, the TownSteel XCE-9000 is a Grade 1 heavy duty electronic classroom intruder cylindrical lockset with keypad for 1-3/4 inch to 2 inch doors, the TownSteel FCE-4000 is an RFID electronic intruder classroom lockset, and the Schlage XE360M is a Grade 1 wireless tubular lock with classroom/storeroom function for 1-3/4 inch doors.
18) What is the difference between the Dorma C150 and the Stanley QCL200?
The Stanley QCL200 is a cylindrical lock supplied keyed different with an SC keyway and a 118F ANSI strike measuring 1-1/8 inch by 2-3/4 inch. The Dorma C150 also offers an SC keyway in its D conventional cylinder with two keys, but its standard strike is the 5001-1316 ANSI strike with dust box at 1-1/4 inch by 4-7/8 inch with a 1-3/16 inch lip. That is a different frame cutout, so confirm which strike the existing frame is prepped for before swapping either way.
19) Can I get access control on the same opening without moving away from a cylindrical lock like the Dorma C150?
Yes. The SDC Electra 7200 is a solenoid controlled cylindrical lock with dual voltage 12/24VDC for doors 1-3/4 inch to 2 inch, suited to openings wired to an access control panel. The SDC E75 is a battery powered electronic cylindrical lockset with keypad access control for 1-3/4 inch to 2-1/8 inch doors where no wiring is available. The Dorma C150 is mechanical, keyed with a single cylinder, so it carries no credential or audit capability.
20) I need passage and privacy locks to match my Dorma C150 entry doors. What should I look at?
The C150 is entry/office only, keyed one side. For the non-keyed openings on the same job, the Cal-Royal Calypso CAL30 is a Grade 1 passage lock and the CAL20 is the Grade 1 privacy version, both rated 1-3/8 to 2 inch doors. The Marks USA 195N is another Grade 1 passage lever, ADA compliant. Trim styling will not match the Dorma lever exactly, so if appearance matters across a corridor, keep the whole opening set in one line.
21) I need a dummy lever to match a Dorma C150 on an inactive leaf. What is available?
The Orca OCL2170 is a Grade 2 medium duty half dummy lever for inactive or pull-side leaves where no latching is required. The C150 itself is a keyed entry/office latching lock, so it is not the right part for an inactive leaf.
