Dormakaba CL780 D LRE 626 – Frequently Asked Questions

1) Will the Dorma CL780 storeroom lever fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The CL780 cylindrical lockset covers a door thickness range of 1-3/8 to 1-3/4 inches, so it goes on older 1-3/8 inch interior doors and on standard 1-3/4 inch commercial doors without any extra kit. Anything thicker than 1-3/4 inches is outside the range.
2) What backset does the Dorma CL780 lockset use, and will it drop into my existing door prep?
The CL780 is a 2-3/4 inch backset lock, which is the standard commercial prep. If the existing bore on the door is set at 2-3/8 inches, the latch hole will not line up and you would need a lock with the shorter backset instead. It ships with an ANSI T strike measuring 1-1/4 by 4-7/8 inches, 1-3/16 inch lip length, square corner, so a frame already cut for a standard ANSI strike takes it directly.
3) What does storeroom function mean on the Dorma CL780, and is that the right lock for a mechanical room?
Storeroom function means the outside lever is always locked. Key retracts the latch for entry but does not leave the lever unlocked, and the inside lever always turns for free egress. That is what you want on mechanical rooms, electrical closets, janitor and stock rooms, where the door must never be left on latch. If staff need to unlock the door and leave it open through the day, an entrance/office function is the better pick, such as the Orca Hardware OCL250 or the Marks USA 195RAB.
4) Do I have to order the Dorma CL780 handed for a left or right hand door?
No handing to specify. The CL780 is non-handed, so one lock covers left and right hand openings, inswing or outswing. For a property manager buying a batch across mixed doors that means a single part number for the whole building.
5) Can I get the Dorma CL780 for a small format interchangeable core keying system?
Yes. Cylinder choice is one of three: D, a conventional cylinder supplied with an SC keyway and 2 keys; J, SFIC less core, for a facility running small format interchangeable cores; and L, a conventional cylinder less core so your locksmith can key it to the existing system. Order J if you are standardizing an SFIC master key system and want to load your own cores on site.
6) Is the Dorma CL780 fire rated for a labeled door?
The CL780 is UL listed to UL 10C, which is the positive pressure fire test standard for door assemblies. It is also ANSI/BHMA Grade 2 certified under A156.2 Series 4000, with an F86 function designation. Those are the numbers a facility or code official asks for on a labeled opening.
7) What is the closest equivalent to the Dorma CL780 storeroom lever lock from another manufacturer?
The Marks USA 175RF is the nearest match. Both are Grade 2 cylindrical storeroom lever locksets on a 2-3/4 inch backset with an ANSI strike, and both are offered less core for small format interchangeable cores - the CL780 in its J - SFIC, Less Core build. The CL780 carries a 1-3/8 inch to 1-3/4 inch door thickness range and is non-handed; the 175RF is described as a clutched lever, which the CL780 is not.
8) I need a Grade 1 storeroom lever instead of a Grade 2 - what should I look at?
The Dorma CL780 is a Grade 2 storeroom lever lockset. Where the specification calls for Grade 1, the Marks USA 195RAB is a Grade 1 Survivor Series clutched lever in the entrance/office function, and the Marks USA 195N is a Grade 1 Survivor Series passage lever with an ADA compliant American lever. Both are mechanical lever locksets like the CL780, but neither is a storeroom function, so confirm which side must stay locked before substituting.
9) Can I use an electronic keypad lock in place of the Dorma CL780 on a storeroom door?
Only if the door thickness works. The CL780 is a keyed mechanical storeroom lever covering 1-3/8 inch to 1-3/4 inch doors. The Schlage XE360M is a Grade 1 wireless tubular lock in a classroom/storeroom function but is listed at 1-3/4 inch door thickness, and the TownSteel XCE-2000 keypad lockset covers 1-3/4 inch to 2 inch. The Lockey E985 and E995 electronic keypad lever locks with key override cover 1-3/8 inch to 1-3/4 inch, the same range as the CL780.
10) We standardize on small format interchangeable cores - which alternatives to the Dorma CL780 accept them?
The CL780 is available in a J - SFIC, Less Core build so your own cores drop in, and also in an L - Conventional Cylinder, Less Core build. Among comparable cylindrical locks, the Marks USA 175RF is a Grade 2 storeroom clutched lever supplied small format IC less core, the Alarm Lock DL2700 electronic cylindrical lock is IC/SFIC compatible, and the BEST 9KZ EZ Series electronic keypad cylindrical lock has a key override function.
11) Grade 2 or Grade 1 storeroom lever, which do I need for a school or hospital corridor?
Grade 2 is the CL780's rating, which suits offices, multi-family, light commercial and back of house storage. On a high traffic institutional corridor or an abuse-prone opening, a Grade 1 lock is the specification you usually see. Among storeroom-capable alternatives, the Marks USA 175RF is another Grade 2 storeroom lever with a 2-3/4 inch backset and ANSI strike, offered SFIC less core. If the spec calls for Grade 1 with an electronic credential, the Schlage XE360M is a Grade 1 classroom/storeroom lock and the TownSteel XCE-2000 is a Grade 1 keypad cylindrical lockset.
12) Which lever design and finish do I have to pick when ordering the Dorma CL780?
Three decisions on the order form: lever style, finish, and cylinder. Lever is LC, LG or LR. Finish is 613 oil rubbed bronze or 626 satin chrome. Cylinder is D conventional with SC keyway and two keys, J SFIC less core, or L conventional less core. Every lever style is offered in both finishes and all three cylinder types, so no combination boxes you out. Satin chrome 626 is the usual choice when matching existing commercial hardware.
13) Can I key the Dorma CL780 into the Schlage keys we already use in the building?
Ordered as cylinder type D, the lock comes with a conventional cylinder cut to the SC keyway and two keys. If your existing system runs on that keyway, a locksmith can key it into the system. If you would rather have your locksmith supply the cylinder entirely, order the L option, which is the conventional cylinder less core.
14) I need keypad or card access on a storeroom door instead of keys. What should I look at instead of a keyed lever?
A keyed storeroom lever like the CL780 needs a physical key for every entry and gives you no record of who came in. If you want codes or credentials on that opening, the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a keypad, 100 user codes and IC/SFIC compatibility, fitting doors 1-5/8 to 1-7/8 inches. The Schlage NDEB is a Grade 1 wireless Bluetooth cylindrical lock for 1-5/8 to 2 inch doors. Note the door thickness ranges: neither covers a 1-3/8 inch door, where the CL780 does.
15) I ordered a storeroom lock but the room actually needs a restroom or a passage latch. What is the right part?
Storeroom is the wrong function for either of those. A restroom or bedroom door wants privacy function, with an inside push or turn button, such as the Orca Hardware OCL240 or the Cal-Royal CAL20, a Grade 1 privacy lock covering 1-3/8 to 2 inch doors. A corridor, closet or stair door that never locks wants passage function, such as the Orca Hardware OCL210 or the Marks USA 195N Grade 1 passage lever.
16) The door is thicker than 1-3/4 inch - what cylindrical lockset covers it?
The Dorma CL780 fits doors from 1-3/8 inch to 1-3/4 inch. For openings up to 2 inches, the Cal-Royal CAL20 privacy and CAL30 passage locks both cover 1-3/8 inch to 2 inch, and the Stanley QCL150 is a Grade 2 entry lever on a 2-3/4 inch backset with a 4-7/8 inch by 1-1/4 inch ASA strike, the same strike size the CL780 uses. Match the function you need: the CL780 is storeroom, the CAL20 is privacy and the CAL30 is passage.
17) Are the Orca OCL series locksets a substitute for the Dorma CL780?
They are the same Grade 2 cylindrical class but not the same function. The CL780 is a keyed single cylinder storeroom lever. The Orca OCL250 is a Grade 2 keyed entrance lockset, the OCL240 is Grade 2 privacy, the OCL210 is Grade 2 passage, and the OCL2170 is a Grade 2 half dummy lever - all medium duty. Of those, only the OCL250 is keyed, and entrance function differs from storeroom in how the outside lever is released.
18) Is the Marks USA 110AB the same thing as the Dorma CL780?
No. Both are Grade 2 bored locksets, but the 110AB is an entry knob lockset with a round knob on a 2-3/8 inch backset in satin stainless, while the CL780 is a storeroom lever on a 2-3/4 inch backset. The backset difference alone means they do not drop into the same bore prep, and lever versus knob trim changes the ADA picture for the opening.
19) We key our building on SC keyway - which other cylindrical locks match the Dorma CL780 on that?
The CL780 ships in a D - Conventional Cylinder build with SC keyway and two keys. The Stanley QCL200 cylindrical lock is also keyed different on the SC keyway, though it comes with a 118F ANSI 1-1/8 inch by 2-3/4 inch strike where the CL780 uses an ANSI T strike 1-1/4 inch by 4-7/8 inch with a 1-3/16 inch lip - so the frame prep is not the same.
20) Which lock should I use for a keyless storeroom door where I do not want to issue keys?
The Dorma CL780 is a keyed lock and needs a cylinder. For keyless mechanical operation, the Lockey 1600 heavy duty keyless knob lock has an adjustable backset and covers 1-1/8 inch to 2 inch doors, and the Lockey 2830 mechanical pushbutton keyless knob lock covers the same range in an auto-locking passage function. Both use knob trim rather than the lever trim the CL780 carries.
21) Does the Dorma CL780 work as an audit trail lock for a controlled stockroom?
No - the CL780 is a mechanical keyed storeroom lever with a conventional or small format interchangeable core cylinder, so access is controlled by key issue rather than by user code. For code-based access with a record of use, the Alarm Lock T3 DL3075 is a Grade 1 electronic cylindrical lock with audit trail and keypad access, and the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with 100 user codes that is IC/SFIC compatible, on doors 1-5/8 inch to 1-7/8 inch.
22) What do I use on a restroom or office door if the Dorma CL780 is the storeroom function?
The CL780 is storeroom only - the outside lever stays locked and the key retracts the latch. For a restroom, the Cal-Royal CAL20 is a Grade 1 privacy lock covering 1-3/8 inch to 2 inch doors and the Orca OCL240 is a Grade 2 privacy lockset. For an office door that latches locked but can be left unlocked, the Orca OCL250 is a Grade 2 keyed entrance lockset and the Marks USA 195RAB is a Grade 1 entrance clutched lever supplied less core.
23) Is the Dorma CL780 lever strong enough for a door that gets slammed and pulled all day?
The key-in-lever trim is through-bolted rather than screwed to the rose alone, which is what resists the loosening you get from vibration and heavy pulls. The chassis is a cylindrical type carrying the ANSI/BHMA Grade 2 certification. For a commercial door with steady daily traffic that is the normal build; for an entry taking genuine abuse, step up to a Grade 1 lock.
24) Is the Stanley QTL230E a passage substitute for the Dorma CL780 trim?
It is a different function. The QTL230E is a Grade 2 Sierra bent lever with a small rose, an adjustable square latch and a 4-7/8 inch by 1-1/4 inch ANSI strike - the same strike size the CL780 uses - but its function is deadbolt, not storeroom. The CL780 is a keyed single cylinder storeroom lever with a 1/2 inch throw latch bolt, so the two are not interchangeable on a door that must latch and lock from the lever.
