Stanley Security QTL240E626-SA-478S – Frequently Asked Questions
1) What door thickness does the Stanley QTL200 series lever lock work on?
Standard range is 1-3/8 inch to 1-3/4 inch, which covers both the common older interior door and the standard commercial 1-3/4 inch leaf. If your doors run thicker than 1-3/4, look at a lockset with a wider range such as the Cal-Royal CAL20 privacy lever, listed for 1-3/8 to 2 inches.
2) Is the QTL240 a keyed lock or just a bathroom privacy lever?
QTL240 is the privacy function, ANSI F76B. It locks with a button on the inside and has no key cylinder, which is what you want on a restroom or bedroom door. If you need a key on the outside, the same series gives you QTL250 entry/office (F82), QTL260 classroom (F84), or QTL270 storeroom (F86).
3) Will the QTL200 latch catch in my existing ANSI strike?
The latchbolt throws 1/2 inch (13mm) and is stainless steel powder metallurgy. The latch faceplate is 1 x 2-1/4 inches standard, and the strike supplied with this privacy lever is the 4-7/8 x 1-1/4 inch ANSI strike, so it drops into a frame already prepped for ANSI strike cutouts. A full lip strike (57mm x 44.4mm) is the series standard, with other strike options offered.
4) I need a privacy lever for a door thicker than 1-3/4 inches - what should I use instead of the QTL240?
The QTL200 series standard door thickness range is 1-3/8 inch to 1-3/4 inch, so a thicker door needs a different lock. The Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lockset with a 1-3/8 inch to 2 inch door thickness range, which covers doors up to a full 2 inches. It is a privacy/bed/bath function like the QTL240, so the opening's purpose does not change - only the chassis depth and the duty grade.
5) The opening needs a key on the outside - what do I order instead of the privacy QTL240?
Privacy function has no cylinder, so a keyed opening needs an entry or storeroom lock. In the Stanley range that is the QTL250 entry/office (ANSI F82) or the QTL270 storeroom (ANSI F86), with SFIC versions as QTL251 and QTL271. Cross-brand, the Orca Hardware OCL250 is a Grade 2 entrance cylindrical lockset, and the Marks USA 175RF SFIC is a Grade 2 storeroom clutched lever prepped for a small format interchangeable core, less core, on a 2-3/4 inch backset.
6) Does someone get trapped if a QTL200 privacy lock is engaged from inside?
No. The series has a built-in anti-lockout feature: once locked from the inside, it releases with a simple push on the interior lever or a turn of the button. For staff-side access on a restroom, that is the function property managers and facility teams usually ask about before specifying privacy hardware.
7) Do I have to specify handing on a Stanley QTL200 lever?
No handing to specify. All QTL200 series lever locksets are non-handed, so one part number works on a left or right hand door. Useful when you are buying a pallet of privacy levers for a multi-family or hospitality retrofit and don't want to count door swings.
8) Can I use my existing small format cores with Stanley QTL200 locks?
Yes, on the keyed functions. The series offers an SFIC option in 6- or 7-pin so you can carry over existing small format cores, and it uses standard door prep with the same thru bolt pattern as other common cylindrical locks. Note this particular privacy lever (QTL240) takes no cylinder at all; the SFIC versions are QTL251 entry, QTL261 classroom, and QTL271 storeroom.
9) What keyways does the Stanley QTL200 series come in for the keyed functions?
Keyway choices are BF-SFIC "F", KW Kwikset, WE Weiser, SC Schlage, GA Yale, LA Sargent, and LC less cylinder. Non-IC cylinders are 6-pin brass, two keys per lockset, and the series supports master keying, grand master keying, and construction keying, so you can fold these into an existing building key system.
10) I need a privacy lever but with a keypad instead of a button. What are my options?
The Stanley QTL240 is strictly mechanical push-button privacy. For electronic privacy on a cylindrical prep, the Alarm Lock Trilogy 4100 is a Grade 1 keypad lock with a privacy function for 1-5/8 to 1-7/8 inch doors, the Schlage CO-100 keypad lock offers a privacy function on 1-3/4 inch doors, and the CENTRIOS CEB100 is a Grade 1 Bluetooth cylindrical lock with a privacy function.
11) What is a comparable Grade 2 privacy lever if the Stanley QTL240 isn't available in the trim I want?
The Orca Hardware OCL240 is a medium duty Grade 2 privacy cylindrical lockset, the closest straight equivalent by grade and function. If you want to step up in duty, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock covering 1-3/8 to 2 inch doors.
12) What is the Grade 1 equivalent if my spec calls for heavy duty privacy instead of Grade 2?
The Stanley QTL240 is certified to ANSI/BHMA A156.2 Grade 2 and tested to 400,000 cycles, which suits light commercial openings. If the drawing calls for Grade 1, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lockset covering the same bed/bath function. For a Grade 1 privacy lever with an electronic keypad rather than a thumbturn, the Schlage CO-100-CY-40-KP is a heavy duty Grade 1 privacy-function cylindrical lock.
13) Same door, but it does not need to lock at all - what replaces the QTL240?
Use a passage function instead of privacy. Within the same Stanley family that is the QTL230 passage, ANSI F75. Across brands, the Orca Hardware OCL210 is a Grade 2 medium duty passage cylindrical lockset and the Dorma CL701 is a Grade 2 non-keyed lever lockset in passage/hall/closet function. All three use the same bored door prep as the QTL240, so you can mix passage and privacy down a corridor without changing the prep.
14) For a classroom door I was quoted the QTL240 - is that the right function?
No. Privacy locks from the inside only and releases with a push of the interior lever, which is not a classroom function. Stanley's classroom functions in the same series are the QTL260 (ANSI F84) and the SFIC QTL261. If the specification calls for a classroom intruder or lockdown capability, the TownSteel XCE-9000 is a Grade 1 electronic classroom intruder cylindrical lockset with a keypad for 1-3/4 inch to 2 inch doors, and the TownSteel FCE-2000 is a Grade 1 standalone motorized classroom lockset with RFID for 1-3/4 inch doors.
15) Can I standardize a whole floor on the QTL200 series, or do I need to mix brands?
The QTL200 series carries privacy (QTL240), passage (QTL230), single dummy (QTL220), entry/office (QTL250 and SFIC QTL251), classroom (QTL260 and QTL261) and storeroom (QTL270 and QTL271), all Grade 2, all non-handed, and all on the same standard bored prep and thru-bolt pattern. That covers a typical office floor in one trim design. Where you need Grade 1 on a high-traffic opening, the Marks USA 195N Grade 1 Survivor Series passage lever and the 195RAB Grade 1 entry clutched lever cover passage and entry at the higher grade.
16) I need a lever rather than a knob on an accessible opening - how does the QTL240 compare to knob locksets?
The Stanley QTL240 uses the Sierra bent lever on a small rose, with heavy-duty torsion springs to prevent lever sag. Knob-trim alternatives in the same bored family include the Marks USA 110AB Grade 2 round knob entry lockset on a 2-3/8 inch backset and the Lockey 1600 keyless knob lock with adjustable backset for 1-1/8 inch to 2 inch doors. If the opening must meet accessible operation requirements, the Marks USA 195N is a Grade 1 passage lever described as ADA compliant. Knob trim is not a substitute where lever trim is specified.
17) Will the Stanley QTL240 work on a 2-1/4 inch thick door, or is there a heavier chassis?
The QTL200 series is built for 1-3/8 inch to 1-3/4 inch doors as standard. For doors up to 2-1/4 inches, the Dorma C150 Grade 1 heavy-duty cylindrical lock in entry/office function and the Dorma C853 Grade 1 single cylinder entry lever both list a 1-3/8 inch to 2-1/4 inch door thickness range. Both of those are keyed entry functions rather than privacy, so confirm the opening's function before substituting.
18) Will the Stanley Sierra lever finish match other hardware on my doors?
This privacy lever is offered in 626 satin chrome, the most common commercial finish. Exposed trim is pressure cast zinc plated to match the finish designation, and the lever is the Sierra (bent) style with a small rose.
19) Do QTL200 levers sag over time like cheap tubular locks?
The series uses heavy-duty torsion springs specifically to prevent lever sag and extend performance life, along with clutching mechanisms and concealed mounting screws. Sag is the usual failure on light commercial lever locks, so that spring design is the reason to pick this over a residential-grade tubular set.
20) What is the difference between the QTL240 and a dummy lever - I only need trim on one leaf?
The QTL240 is a working privacy lock with a 1/2 inch stainless latchbolt and an interior locking button. If the leaf is inactive and you only need matching trim with no latch, use a dummy instead: the Stanley QTL220 single dummy in the same series, the Dorma C501 single dummy lever lockset rated Grade 2 for 1-3/8 inch to 1-3/4 inch doors, or the Orca OCL2170 Grade 2 half dummy lever. A dummy has no latch prep requirement, so it is not interchangeable with a privacy lock on a door that must actually latch closed.
