Stanley Security DORQCL240 – Frequently Asked Questions

1) Will the Stanley Security QCL240 privacy lever fit a 1-3/8 inch interior door?
Yes. The QCL240 covers door thicknesses from 1-3/8 inches (35mm) up to 2 inches (51mm), so a standard older interior door at 1-3/8 and a commercial 1-3/4 door both work with the same lock. Door prep is a 2-1/8 inch (54mm) diameter cross bore.
2) Do I have to pick a backset when ordering the QCL240, and which one is standard?
Backset is a required selection: 2-3/4 inch or 2-3/8 inch. The 2-3/4 inch (70mm) square corner latch is the standard for this series, and 2-3/8 inch (60mm) is the common choice on residential-style doors with an existing 2-3/8 bore centerline. Measure from the door edge to the center of the existing 2-1/8 inch cross bore and match it.
3) Will the QCL240 latch drop into my existing strike, or do I need a new one?
The QCL240 ships with a 1/2 inch (12.7mm) latch throw and a 1-1/8 x 2-1/4 inch latch faceplate, with an ANSI 1-1/4 x 4-7/8 inch strike as standard. If your frame already has an ANSI 4-7/8 inch strike prep, it lines up. On a frame prepped for a small T-strike, other strike options are offered in the series, so specify the strike that matches the frame rather than reworking the jamb.
4) Is a privacy lever like this allowed on a fire-rated door?
The QCL200 series is UL/cUL listed 3 hour for A label single door applications up to 4 by 8 feet, and is UL10C/UBC 7-2 (1997) positive pressure rated plus UL10B pressure rated. For fire-rated double door openings, the 3/4 inch latch throw option is the one to specify instead of the standard 1/2 inch throw.
5) Can I replace an existing cylindrical lever lock with the QCL240 without redrilling the door?
In most cases yes. The QCL200 series uses standard door prep, a 2-1/8 inch cross bore, and the same thru-bolt pattern found in other common cylindrical locks, which is what makes the retrofit quick. Confirm the existing backset is 2-3/4 or 2-3/8 inches and pick the matching option.
6) What is a direct Grade 2 privacy cylindrical lever equivalent to the Stanley Security QCL240?
The Orca Hardware OCL240 is the closest straight swap: it is a Grade 2 privacy/bed/bath cylindrical lockset in a medium duty rating, matching the QCL240's Grade 2 certification and privacy/bed/bath function. Both are lever-operated cylindrical locks for bored door prep, so an opening prepped for one accepts the other's function.
7) If a bathroom or patient-room door needs a higher grade than the QCL240, what privacy lever should I specify?
Step up to the Cal-Royal CAL20, a Grade 1 extra heavy duty privacy lock in the Calypso series with a 1-3/8 inch to 2 inch door thickness range. That thickness range matches the QCL240's standard 1-3/8 inch to 2 inch doors, so the same door stock works, while the CAL20 carries a Grade 1 rating against the QCL240's Grade 2.
8) What does the privacy function on the QCL240 actually do on a bathroom or bedroom door?
Privacy function means a push or turn button on the inside locks the outside lever, and there is no keyway on the outside. It is for bath, bedroom and dressing room doors where you want occupancy privacy, not security. If you need a keyed lock on that opening, move to the Entry/Office, Storeroom or Classroom function in the same QCL200 series.
9) Is a Grade 2 lock enough for an apartment building or hotel guest bath door?
Yes, that is exactly the target. The QCL200 series is ANSI/BHMA A156.2 Grade 2 and built for non-institutional light commercial work: hospitality, multi-family housing and commercial office space. For a school corridor or other high-abuse institutional opening, step up to a Grade 1 cylindrical such as the Cal-Royal CAL20 privacy lock.
10) Is the QCL240 ADA compliant for lever operation?
Yes. The QCL200 series meets ANSI A117.1 accessibility code, and the Sierra lever on the QCL240 is an operable lever rather than a knob, so it satisfies the no-tight-grasping requirement on accessible routes.
11) What finishes does the QCL240 privacy lever come in, and will they match the other doors in my building?
Five finishes: 605 Bright Brass, 613 Oil Rubbed Bronze, 619 Satin Nickel, 625 Bright Chrome and 626 Satin Chrome. Exposed trim is pressure cast zinc plated to match the finish designation, so the levers match across the other functions in the QCL200 series if you are standardizing a floor or a whole property.
12) What is the difference between the QCL240 privacy lever and the Orca OCL240?
Both are Grade 2 cylindrical locksets in the privacy/bed/bath function, so functionally they cover the same opening. The Orca OCL240 is catalogued as medium duty. The QCL240 carries the QCL200 series' stated listings, ANSI/BHMA A156.2 Grade 2, ANSI A117.1 accessibility, and UL/cUL 3 hour A label, and comes in five plated finishes.
13) I need a keyless lock on a bedroom door but with code entry, not just a privacy button. What should I look at instead?
A mechanical privacy lock like the QCL240 has no code entry at all, just an inside button. For keypad privacy, the Alarm Lock Trilogy 4100 is a Grade 1 electronic cylindrical lock with a privacy function, listed for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100 standalone keypad cylindrical lock also carries a privacy function for 1-3/4 inch doors. Note both have narrower door thickness ranges than the QCL240's 1-3/8 to 2 inches.
14) Does the QCL200 series work with our existing small format interchangeable cores?
On the keyed functions, yes. The QCL200 series offers SFIC versions of Entry/Office, Corridor, Classroom and Storeroom, so existing small format cores can be carried over. The QCL240 privacy function itself is unkeyed, so no core applies to it.
15) Is the QCL240 suitable for a coastal project with hurricane hardware requirements?
The QCL200 series offers a hurricane compliant option with a Miami Dade Notice of Acceptance, and that option uses the 3/4 inch latch throw rather than the standard 1/2 inch. If the opening is under a wind-borne debris requirement, the hurricane compliant configuration is what has to be specified, not the standard privacy latch.
16) Is the Alarm Lock Trilogy 4100 a substitute for the QCL240 privacy lever?
Not a like-for-like one. The Trilogy 4100 is a Grade 1 electronic cylindrical lock with a keypad and a privacy/bed/bath function for doors 1-5/8 inch to 1-7/8 inch thick, so it shares the privacy function but adds battery-powered keypad access and narrows the door thickness window. The QCL240 is a purely mechanical Grade 2 privacy lever for 1-3/8 inch to 2 inch doors with no power or programming.
17) Will a Lockey keyless lock work where I would otherwise use a QCL240?
They solve different problems. 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 thickness range. Both are code-entry knob products, where the QCL240 is a lever lockset whose privacy/bed/bath function locks from the inside with no code at all - and the QCL240 is ADA compliant under ANSI A117.1.
18) For a classroom or other institutional opening, is the QCL240 the right series?
The QCL200 series is positioned for non-institutional work - hospitality, multi-family and commercial office - and carries ANSI/BHMA A156.2 Grade 2. For classroom duty, look at Grade 1 classroom locksets such as the TownSteel XCE-2000 electronic keypad cylindrical lockset, heavy duty for 1-3/4 inch to 2 inch doors, or the Schlage XE360M Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors.
19) What is the difference between the QCL240 and the Dorma C150 from the same manufacturer family?
The C150 is a Grade 1 heavy-duty cylindrical lock in entry/office function for doors 1-3/8 inch to 2-1/4 inch thick. The QCL240 is the Grade 2 QCL200 series in privacy/bed/bath function for 1-3/8 inch to 2 inch doors. So the difference is both the grade and the function - keyed entry versus inside privacy.
20) Will the QCL240 lever sag over time like cheap levers do?
The QCL200 series uses heavy-duty torsion springs specifically to keep the lever from sagging, along with a thru-bolt design and clutching mechanism on the keyed functions for vandal resistance. Sag is the usual failure on light-duty levers in high-traffic multi-family corridors, and the torsion spring return is what addresses it.
21) Can I get the QCL200 series with a 5 inch backset for a door with a wide stile or a narrow-frame condition?
Yes, the QCL200 series lists a 5 inch (127mm) backset in addition to the 2-3/4 inch standard and 2-3/8 inch. A 5 inch backset is the one to use when the lever needs to clear a glass light or a wide rail, since the 2-3/4 position would put the lever too close to the edge condition.
22) Which lever styles are available in the QCL200 series besides Sierra?
Three lever designs: E Sierra, M Summit and A Slate. The QCL240 as configured uses the E Sierra lever with square corner latch, so if the rest of the building is on Summit or Slate trim, specify that lever code to keep the openings matching.
23) Can I use a knob lockset instead of the QCL240 lever?
Only where accessibility rules do not apply. The Marks USA 110AB is a Grade 2 round knob entry lockset on a 2-3/8 inch backset, which matches one of the two backsets the QCL240 is ordered in, but it is a knob and a keyed entry function. The QCL240 is a privacy lever certified to ANSI A117.1 for accessibility.
24) I want a Grade 1 lever in passage function for corridor doors alongside QCL240 privacy locks on the bathrooms - what works?
The Marks USA 195N is a Grade 1 Survivor series passage lever lockset with an American lever and ADA compliance, and the Cal-Royal CAL30 is a Grade 1 extra heavy duty passage lock covering 1-3/8 inch to 2 inch doors, the same thickness range the QCL240 is built for. Both latch without locking, so they pair with the QCL240 on the privacy openings.
