Dorma CL740 Grade 2 Privacy/Bed/Bath, Non-Keyed Cylinder Lever Lockset

Both. The CL740 covers a 1-3/8 inch to 1-3/4 inch door thickness range, so it works on older interior wood doors and on standard 1-3/4 inch commercial doors without a thickness kit. Backset is 2-3/8 inches, the shorter of the two standard bored-lock backsets, so check the cross-bore center on the door you are retrofitting.

The CL740 chassis is non-handed, so you can order before you have confirmed the swing. Handing only enters into the lever choice itself, so pick the lever design with the door's direction in mind and the lock body will take care of itself.

It ships with the 5001 strike, an ANSI strike with a cylindrical lock cutout, and the 17130 latch, which has a 1 x 2-1/4 inch front, 7/8 inch diameter case and square corners. If your frame is already prepped for an ANSI strike and the door has a 7/8 inch latch bore at a 2-3/8 inch backset, it goes straight in. A frame cut for a small 2-1/4 x 1-1/8 inch T-strike will need to be reworked or the strike swapped.

F76 is the privacy function. The lever locks from the inside with a pushbutton or turn, both levers still retract the latch from inside, and the outside lever is locked until it is released. There is no key and no cylinder. It is the right pick for bedrooms, bathrooms, and single-occupancy rooms where staff need to get in but nobody carries a key. If you need a room that stays latched and opens with a key from outside, this is the wrong function.

Grade 2 is the standard commercial spec for interior doors that see normal traffic, and the CL740 is ANSI/BHMA A156.2 Series 4000 Grade 2 certified, UL listed for UL 10C, and through-bolted for resistance to vibration and loosening. That covers multi-family bedrooms and bathrooms and most office and light-institutional restrooms. For a high-abuse restroom in a school or transit facility, a Grade 1 privacy lock such as the Cal-Royal CAL20 is the heavier option.

The CL700 Series is UL listed for UL 10C, which is the positive pressure fire door test standard, so the lockset is listed for use on fire rated door assemblies. Privacy function has no deadbolt and the latch is the auxiliary deadlocking type, so the door stays latched in the frame.

The Alarm Lock Trilogy 4100 is a Grade 1 electronic cylindrical lock with a privacy function and keypad, and the Schlage CO-100 is a Grade 1 standalone electronic cylindrical lock in the privacy function with keypad and cylinder options. Both hold the same privacy/bed/bath function as the mechanical Dorma CL740 while adding code entry. Door prep differs: the Trilogy 4100 covers 1-5/8 inch to 1-7/8 inch doors and the CO-100 is listed at 1-3/4 inch, where the CL740 spans 1-3/8 inch to 1-3/4 inch, so thin doors that accept the CL740 will not accept either electronic unit.

The Dorma CL740 is a Grade 2 cylindrical privacy/bed/bath lever lockset. For the same privacy function at Grade 1, the Cal-Royal CAL20 is an extra heavy duty privacy lock listed as Grade 1 with a 1-3/8 inch to 2 inch door thickness range, compared with the CL740's 1-3/8 inch to 1-3/4 inch range. Both are mechanical, non-keyed privacy functions, so the bathroom or bedroom door behavior is the same; the CAL20 covers thicker doors and carries the higher ANSI/BHMA grade.

The CL740 is the privacy/bed/bath function, so it has a thumbturn and an emergency release. For a door that latches but never locks, use a passage function instead: the Orca Hardware OCL210 is a Grade 2 medium duty passage/hall/closet cylindrical lockset, and the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lock covering 1-3/8 inch to 2 inch doors. The Marks USA 195N is a Grade 1 passage lever in the Survivor Series with an ADA compliant American lever. All three latch the door with no locking function on either side.

The Orca Hardware OCL240 is the direct peer: a Grade 2 medium duty privacy cylindrical lockset, the same grade and same privacy/bed/bath function as the Dorma CL740. If the package also needs matching trim on non-privacy openings, Orca runs the same Grade 2 medium duty family across functions - the OCL210 passage, the OCL250 entrance, and the OCL2170 half dummy lever - so bedrooms, corridor doors, entries, and inactive leaves can all be specified from one series.

The CL740 is the non-keyed privacy/bed/bath function, so it takes no cylinder - a keyed opening needs a different function. For a keyed lever at the same Grade 2 level, the Stanley Security QCL150 is a Grade 2 entry lever with the Sierra bent lever and rose, supplied less cylinder with a 2-3/4 inch square backset latch and a 4-7/8 inch by 1-1/4 inch ASA strike, and the Orca Hardware OCL250 is a Grade 2 medium duty entrance cylindrical lockset. The Marks USA 175RF is a Grade 2 storeroom clutched lever with small format IC, less core, on a 2-3/4 inch backset - note that both Stanley and Marks options use a 2-3/4 inch backset where the CL740 uses 2-3/8 inch, so confirm the bore in the door.

Three lever designs, LR, LC, and LG, each in 613 Oil Rubbed Bronze or 626 Satin Chrome. All six combinations are orderable, so you can match an existing lever shape and still get the finish that matches the rest of the openings. If you are standardizing a floor, order the same lever code across passage and privacy doors so the trim reads the same down the corridor.

No. The CL740 is the privacy/bed/bath model, so it locks from the inside. For a closet, corridor, or storeroom door that just needs to latch and never lock, look at a passage function lockset such as the Orca Hardware OCL210 or the Marks USA 195N. Same cylindrical prep, no locking button.

Both are Grade 2 privacy/bed/bath cylindrical locksets, so they land on the same door prep and do the same job. The CL740 carries the ANSI/BHMA F76 designation and UL 10C listing, is through-bolted, and offers three lever designs in two finishes. The OCL240 is catalogued as medium duty Grade 2 privacy. If you are matching existing Dorma trim in the building, the CL740 keeps the lever family consistent.

The Dorma CL740 is built for 1-3/8 inch to 1-3/4 inch doors. For a 2 inch door in the same privacy/bed/bath function, the Cal-Royal CAL20 Grade 1 extra heavy duty privacy lock covers 1-3/8 inch to 2 inch. If the opening only needs a latch with no locking, the Cal-Royal CAL30 Grade 1 passage lock spans the same 1-3/8 inch to 2 inch range.

Several cylindrical locks sit in the same chassis family without giving privacy. The Orca Hardware OCL2170 is a Grade 2 half dummy lever - trim only, with no latch. The Marks USA 110AB is a Grade 2 entrance/office knob lockset and the Marks USA 195RAB is a Grade 1 entry clutched lever, both keyed entry functions rather than privacy. The TownSteel XCE-2000 and XCE-9000 are Grade 1 classroom function electronic locksets, and the Schlage XE360M is a Grade 1 classroom/storeroom wireless tubular lock. None of those provide the inside thumbturn and outside emergency release the Dorma CL740 supplies for a bed or bath door.

The Dorma CL740 is a mechanical non-keyed privacy lever with a lever handle on a 2-3/8 inch backset, controlled from inside the room. A keyless pushbutton alternative works differently: the Lockey 2830 is a mechanical pushbutton keyless knob lock with an auto-locking passage function for 1-1/8 inch to 2 inch doors, and the Lockey 1600 is a heavy duty mechanical keyless knob lock with an adjustable backset over the same 1-1/8 inch to 2 inch range. Both Lockey units are knob trim and gate entry by code rather than giving an occupant a privacy thumbturn, so they suit a staff or storage door rather than a bed or bath opening.

The Lockey E985 and E995 are electronic keypad lever locks built for 1-3/8 inch to 1-3/4 inch doors, the same door thickness range the Dorma CL740 covers, and both keep the lever trim. The E985 adds remote control with key override; the E995 is remote control and battery powered. Where the CL740 is a mechanical privacy function operated from inside the room, these control the outside lever by code.

The Dorma CL740 ships with a 17130 latch, 1 inch by 2-1/4 inch front, 7/8 inch diameter with square corner, and a 5001 ANSI strike with cylindrical lock cutout, on a 2-3/8 inch backset. Two peers arrive prepped differently: the Stanley Security QCL150 uses a square 2-3/4 inch backset latch with a 4-7/8 inch by 1-1/4 inch ASA strike, and the Stanley QCL200 comes with a 118F ANSI 1-1/8 inch by 2-3/4 inch strike. The Marks USA 175RF is also a 2-3/4 inch backset with an ANSI strike. Check the existing frame cutout before swapping, since the strike sizes are not interchangeable.

The Dorma CL740 is a Grade 2 mechanical privacy lever. For higher duty electronic options, the Schlage NDEB is a Grade 1 heavy duty ENGAGE Series wireless cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader for 1-5/8 inch to 2 inch doors, and the Alarm Lock T3 DL3075 is a Grade 1 electronic cylindrical lock with audit trail and keypad access. The TownSteel FCE-2000 is a Grade 1 heavy duty standalone motorized cylindrical lockset with RFID for 1-3/4 inch doors. These are access control units rather than occupant-operated privacy locks, so they change how the room is secured as well as the duty rating.

Often not, because of door thickness. The Dorma CL740 covers 1-3/8 inch to 1-3/4 inch doors. The SDC Electra 7200 solenoid controlled cylindrical lock is listed for 1-3/4 inch to 2 inch, the SDC E75 battery powered keypad lockset for 1-3/4 inch to 2-1/8 inch, and the Alarm Lock DL2700 and DL5200 for 1-5/8 inch to 1-7/8 inch. Only doors at the top of the CL740 range fall inside those windows, so measure the leaf before ordering an electrified replacement.
