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 C153 D LRC 626 – Frequently Asked Questions

1) Will the Dorma C153 entry lever fit a 1-3/8 inch wood door and a 1-3/4 inch hollow metal door?
Both work. The C153 cylindrical lockset covers doors from 1-3/8 inches up to 2-1/4 inches thick, and it installs in wood or hollow metal doors using the ANSI/BHMA A156.115 cylindrical prep. That upper end of 2-1/4 inches also covers heavier exterior and lead-lined leaves that many cylindrical locks top out below.
2) Does the Dorma C153 use a 2-3/8 or 2-3/4 inch backset?
2-3/4 inches. The C153 ships with the 10252 latch: 2-3/4 inch backset, 1-1/8 x 2-1/4 inch front, 1 inch diameter, square corner. If your existing bore is on a 2-3/8 inch backset (common on residential-prep doors), the cross-bore will not line up without re-prepping the edge.
3) What does the ANSI F109 entry function on the Dorma C153 actually do in daily use?
F109 is the standard office/entry lock. The deadlocking latch is retracted by the lever from either side unless the inside push button is pushed, which locks the outside lever. A key outside releases that button and unlocks the outside lever. Turning the inside lever also pops the button back out, so the door unlocks on exit, unless the button is pushed AND turned, which holds the outside locked until someone deliberately releases it. The inside lever always retracts the latch, so it is free egress at all times.
4) Can I get the Dorma C153 with a small format interchangeable core so it keys into my existing SFIC system?
Yes. Three cylinder choices are offered: J for SFIC less core, which takes your own 6 or 7 pin SFIC and keys into the system you already run; D, a conventional cylinder in SC keyway supplied with two keys; and L, a conventional cylinder less core so your locksmith pins it to your existing conventional system. All three are single cylinder, keyed outside only.
5) Will the Dorma C153 hold up on a high-traffic door where people hang on the lever?
That is what the freewheeling trim is for. When the lock is secured, the outside lever swings freely through a 60 degree arc without pulling on the retractor, so someone yanking a locked lever is not loading the mechanism. Inside, the lever trim runs a cast stainless steel retractor on roller bearings. It is a Grade 1 heavy-duty lockset, the top ANSI/BHMA durability tier, which is the grade normally specified for school, healthcare, and multi-family corridor doors.
6) Can I standardize a whole building on the Dorma C153 and keep one key?
That is the usual way it is specified. Order the J cylinder option (SFIC, less core) across every opening and drop in cores from your existing small format system, so one master key runs the building and rekeying a unit is a core swap rather than a lock change. Choose L instead if you run conventional cylinders. The D option comes as a conventional cylinder in the SC keyway with two keys, which suits one-off replacements more than a keyed system. Finish and lever stay consistent across the range, so the C153 matches other C100 Series openings on the same floor.
7) What is the closest Grade 1 entry lever lockset to the Dorma C153 if I need a different brand on the same opening?
The Marks USA 195RAB is the nearest match in a mechanical key lockset. Both are Grade 1 entry-function clutched lever locksets: the C153 is a Grade 1 entry-function cylindrical lock with lever trim, and the 195RAB is a Grade 1 entry/office clutched lever lockset in the Survivor Series, supplied less core. The C153 is offered with a conventional cylinder with SC keyway and two keys, SFIC less core, or conventional less core, so if your keying program is SFIC or you core the lock yourself, either part can be ordered without a core.
8) The door does not need to be keyed - it just needs to latch. What replaces a Dorma C153 in that case?
Move to a passage lockset, because the C153 is a keyed single-cylinder entry lock and every one of its functions assumes a key and a push button. For Grade 1 passage in a lever, the Marks USA 195N is a Grade 1 passage lever lockset in the Survivor Series with an ADA compliant American lever, and the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lockset in the Calypso Series fitting doors 1-3/8 inch to 2 inch thick. In Grade 2, the Orca OCL210 is a medium duty passage cylindrical lockset.
9) I want to get rid of keys on this door. What electronic lock goes in place of a Dorma C153?
Several standalone electronic cylindrical locks fit the same bored lock 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 Schlage NDEB is a Grade 1 heavy duty ENGAGE Series wireless cylindrical lock with a Bluetooth Low Energy reader, for doors 1-5/8 inch to 2 inch. The BEST 9KZ EZ Series is an electronic keypad cylindrical lock with key override. Check door thickness first: the C153 covers 1-3/8 inch to 2-1/4 inch, a wider band than any of these.
10) Will a Marks USA 110AB entry knob work where a Dorma C153 is specified?
Only if the spec allows Grade 2 and a knob. The 110AB is a Grade 2 entry/office knob lockset with a round knob on a 2-3/8 inch backset in satin stainless steel. The C153 is Grade 1 with lever trim on a 2-3/4 inch backset, and its R rectangular lever is ADA compliant with a 1/2 inch return. The backset difference alone means the door bore centerline is not the same, and a knob does not satisfy an ADA lever requirement.
11) Which cylindrical lock should I use on a 2-1/4 inch thick door instead of an electronic one?
The Dorma C153 covers doors 1-3/8 inch to 2-1/4 inch, the widest thickness range among the cylindrical locks in its class here. Among the alternatives, the Cal-Royal CAL20 and CAL30 stop at 2 inch, the Schlage NDEB runs 1-5/8 inch to 2 inch, the SDC E75 runs 1-3/4 inch to 2-1/8 inch, and the Schlage CO-100 and TownSteel FCE-2000 are 1-3/4 inch. For a thick door on an entry function, the C153 is the one that reaches.
12) What do I use instead of a Dorma C153 on a door that has to unlock from an access control panel?
An electrified lock, not a mechanical one. The C153 is a keyed mechanical cylindrical lock with no electrical function. The SDC Electra 7200 Series is a solenoid controlled cylindrical lock with dual voltage 12/24VDC for doors 1-3/4 inch to 2 inch, which is the type that takes a signal from a panel. The SDC E75 Series is battery powered with keypad access control and fits 1-3/4 inch to 2-1/8 inch, which suits an opening where running wire is not practical.
13) I need a storeroom function lock, not entry. What is close to the Dorma C153?
The C153 is an entry-function lock with an inside push button, so the outside lever can be left unlocked - a storeroom door needs the outside lever always locked. The Marks USA 175RF SFIC is a Grade 2 storeroom clutched lever lockset on a 2-3/4 inch backset with an ANSI strike, supplied small format IC less core, which matches the C153 backset and its SFIC less-core cylinder option. The Schlage XE360M is a Grade 1 wireless tubular lock in a classroom/storeroom function for 1-3/4 inch doors if the door is going electronic.
14) Do I have to order the Dorma C153 handed for left or right doors?
Handing on the C153 follows the lever you pick, not a separate hand code on the lock body itself. Confirm the swing of the opening against the lever style you order.
15) What lever, rose, and finish combinations does the Dorma C153 come in?
Three levers (LC, LG, LR), two roses (C rose at 3-1/2 inch diameter, or the E stepped rose, also 3-1/2 inch), and eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome. If you are matching existing openings in a building, the rose diameter is the same either way, so switching between C and E is a look decision rather than a prep change.
16) Is the Dorma C153 lever ADA compliant for a commercial building?
The R rectangular lever is ADA compliant with a 1/2 inch return. It is a lever rather than a knob, so it operates without grasping or twisting, and this is a commercial-duty lockset rather than a residential one.
17) I need a keyed entry lever, not a privacy or passage set. Is the Dorma C153 the right one?
Yes, the C153 is the keyed entrance function in the C100 family. If you need the non-keyed functions on the same doors, the Cal-Royal Calypso CAL30 is a Grade 1 passage lockset and the CAL20 is the Grade 1 privacy version, both rated for 1-3/8 to 2 inch doors. Marks USA 195N is another Grade 1 passage lever. Keep in mind those are different brands, so they will not share a keyway or a lever design with the Dorma.
18) What is the difference between the Dorma C153 and an electronic keypad cylindrical lock for a tenant entry door?
The C153 is mechanical and key-operated, so there is no battery, no programming, and no audit trail, and rekeying means pulling the cylinder. If you need codes instead of keys on the same kind of door, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone keypad cylindrical lock holding 100 user codes and taking IC/SFIC, and the Alarm Lock T3 DL3075 adds an audit trail. Watch the door thickness: those DL2700 and DL4100 units are listed for 1-5/8 to 1-7/8 inch doors, where the C153 spans 1-3/8 to 2-1/4 inches, so on a thin or unusually thick leaf the mechanical lock is the one that fits.
19) What is a comparable Grade 1 entry lever to the Dorma C153 from another brand?
Marks USA 195RAB, from the Grade 1 Survivor Series, is the closest straight equivalent: entry function, clutched American lever, supplied less core so you pin it to your own system, same as the C153 L and J cylinder options. If Grade 1 is not required, the Stanley QCL150 is an entry lever with a square 2-3/4 inch backset latch and a 4-7/8 x 1-1/4 inch ASA strike, matching the C153 prep, and the Orca OCL250 is a medium-duty Grade 2 entrance lockset. The Marks 175RF is storeroom function, not entry, so it locks differently.
20) If I order the Dorma C153 less core, what else do I need to buy to finish the job?
Just the cylinder. The latch (10252) and the ANSI strike with dustbox (5001-1316) come with the lockset, so the door and frame hardware is covered. With the J option you supply an SFIC core; with L you supply a conventional cylinder, pinned to your system. Order the D option instead and it arrives with a conventional SC keyway cylinder and two keys, ready to hang.
21) What is the difference between the Dorma C153 and the Stanley QCL200?
Keying and how you order it. The Stanley QCL200 is a cylindrical lock supplied keyed different with an SC keyway and a 118F ANSI 1-1/8 inch by 2-3/4 inch strike. The C153 is offered with a conventional cylinder in SC keyway with two keys, or as SFIC less core, or conventional less core, and its standard strike is the 5001-1316 ANSI strike with dustbox at 1-1/4 inch by 4-7/8 inch with a 1-3/16 inch lip. The strikes are different sizes, so confirm the existing frame prep before treating one as a drop-in for the other.
22) Is a Grade 1 classroom electronic lock like the TownSteel XCE-2000 a substitute for a Dorma C153?
Not on the same opening, no - the function is different. The C153 is ANSI F109 entry: the outside trim is locked by the inside push button and released by key or by operating the inside trim, and the inside trim always retracts the latch. The TownSteel XCE-2000 is a Grade 1 heavy duty electronic cylindrical lockset with keypad in a classroom function, and the XCE-9000 is the classroom intruder version, both for doors 1-3/4 inch to 2 inch. Classroom function is specified for lockdown, not for an office or tenant entry door.
23) Is the Orca OCL250 entrance lockset the same thing as a Dorma C153?
They share the entrance function but not the duty rating. The Orca OCL250 is a Grade 2 medium duty entrance cylindrical lockset. The C153 is Grade 1 and built for heavy traffic, with a cast stainless steel retractor on roller bearings and a freewheeling lever that moves through a 60 degree arc when locked without operating the latch bolt, which protects the mechanism from forced lever torque. On a high-traffic commercial opening the two are not interchangeable.
24) For a multi-family unit entry door, is the Kwikset 912TNL SmartCode a substitute for a Dorma C153?
They serve different door standards. 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. The C153 is a Grade 1 commercial cylindrical lock with a 2-3/4 inch backset and comes in eight finishes from bright brass through matte black and satin chrome, so it can be matched across a building's existing hardware. Where the spec calls for Grade 1 commercial hardware, the C153 is the one that meets it; where a resident wants code and app entry on a single unit, the SmartCode is the type of product that does that.
25) A Lockey keyless knob lock was suggested in place of a Dorma C153 - does that work?
Only if the opening does not need a lever or a key. The Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset for doors 1-1/8 inch to 2 inch, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with auto-locking passage function over the same thickness range. Both are knobs, so neither satisfies a lever requirement; the C153 uses lever trim, and its R rectangular lever is ADA compliant with a 1/2 inch return. The C153 is also keyed single cylinder, which the keyless Lockeys are not.
26) Which entry lock lets me standardize finishes across a whole building?
The Dorma C153 is offered in eight ANSI 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 - across three lever styles (LC, LG, LR) and two rose options, a 3-1/2 inch C rose and a 3-1/2 inch stepped E rose. Among the entry-function alternatives, the Marks USA 110AB is a Grade 2 knob lockset in satin stainless steel and the Stanley QCL150 is a Grade 2 entry lever with a Sierra bent lever. For matching trim across mixed openings in one facility, the C153 gives the widest finish and trim selection of the group.
