Stanley Security QCL250 E 626 – Frequently Asked Questions

1) Will the Stanley Security QCL250 cylindrical lock fit a 1-3/8 inch door?
Yes. The QCL200 series is built for doors from 1-3/8 inches (35mm) up to 2 inches (51mm), so a 1-3/8 inch older interior door and a standard 1-3/4 inch commercial door both work with the same lock. Door prep is a 2-1/8 inch (54mm) cross bore, which is the standard bored-lock prep already in most doors.
2) What backset does the QCL250 come with, and can I get it for a 2-3/8 inch prep?
Square 2-3/4 inch (70mm) backset is the standard, and a 2-3/8 inch (60mm) version is orderable from the backset dropdown when ordering. Those are the two backsets found on nearly every bored door prep, so measure from the door edge to the center of the bore before you order. A 5 inch (127mm) backset is also offered in the QCL200 series for doors with wide stiles or glass lites.
3) Will the QCL250 latch into the strike plate that is already in my frame?
It depends on what strike is in the frame. The QCL200 ships standard with a full ANSI strike, 1-1/4 inches (32mm) x 4-7/8 inches (124mm), and the latch faceplate is 1-1/8 x 2-1/4 inches (29 x 57mm). Latch throw is 1/2 inch (12.7mm) steel on the keyed side. If your frame has an ANSI-prepped strike cutout, the standard strike drops in. If it has a smaller T-strike or a non-ANSI cutout, other strike options are offered in the series, and the meta record for this lock cites a 118F ANSI strike at 1-1/8 x 2-3/4 inches as one of them.
4) Does the Entry/Office function on the QCL250 lock from the inside without a key?
Entry/Office is the function where the outside lever is locked and unlocked by a pushbutton or turn on the inside, and the key retracts the latch from outside. That is the function this QCL250 is built as. If you want a lock that stays locked outside at all times and is only opened by key, that is the Storeroom function in the same QCL200 series; if you need the outside lever locked only by key from the corridor, that is the Corridor function. Classroom, Privacy, Passage, Communicating and Dummy are also built in this series.
5) Is the Dormakaba QCL200 series lock fire rated for a labeled door?
Yes. QCL200 series locks are UL/cUL listed for 3 hours on "A" label single doors up to 4 feet by 8 feet, and are UL10C/UBC 7-2 (1997) positive pressure rated as well as UL10B pressure rated. They also carry ANSI/BHMA A156.2 Grade 2 and meet ANSI A117.1 for accessibility. One caution on fire-rated pairs: the standard latch is a 1/2 inch throw, and fire-rated double door applications call for the 3/4 inch throw latch option, which has to be specified.
6) Is a Grade 2 cylindrical lock enough for an apartment building or an office suite?
For hospitality, multi-family residences and commercial office space, yes. That is exactly what the QCL200 series is aimed at, and it holds ANSI/BHMA A156.2 Grade 2. Where it is not the right call is a high-traffic institutional opening, a school corridor or a hospital, where a Grade 1 lock is the normal spec. For those, the Dorma C150 in Entry/Office function is Grade 1 with a 1-3/8 to 2-1/4 inch door thickness range, and the Marks USA 195RAB clutched entry lever is Grade 1 in the Survivor Series.
7) Can I keep my existing small format interchangeable cores when I swap to QCL200 locks?
Yes. The QCL200 series is offered with an SFIC option that takes your existing small format cores, so a building already keyed on SFIC can standardize on these without rekeying the system. SFIC versions are built in Entry/Office, Corridor, Classroom and Storeroom functions. Note that this QCL250 as configured is the standard Entry/Office cylinder, so the SFIC version has to be specified separately.
8) Will a QCL200 lock drop into the holes left by the lock I am taking off?
In most cases it will. The QCL200 uses standard door prep, a 2-1/8 inch (54mm) cross bore, and the same thru bolt pattern found in other common cylindrical locks, which is what makes it a straight retrofit on an existing bored opening. What you still need to confirm is the backset (2-3/4 or 2-3/8 inch) and the frame strike cutout, since those are what actually differ door to door.
9) What is the closest Grade 2 entrance cylindrical lever lock to the Stanley Security QCL250?
The Orca Hardware OCL250 is the nearest straight equivalent. It is a Grade 2 entrance cylindrical lockset in a medium duty level, matching the QCL250 on grade and on entrance function. The QCL250 is a Grade 2 cylindrical lock in entrance function with the Sierra lever, offered in bright brass, oil rubbed bronze, satin nickel, bright chrome and satin chrome. If the opening needs a keyed lever with the same certification level and the Sierra, Summit or Slate lever styling is not a requirement, the OCL250 covers the same duty class.
10) Which entrance lever lock should be used on a door thicker than 2 inches?
The QCL250 series is built for a standard door thickness of 1-3/8 inch to 2 inch. For a thicker leaf, the Dorma C150 Grade 1 heavy-duty entrance/office cylindrical lock and the Dorma C853 Grade 1 entrance lever lockset both list a door thickness range of 1-3/8 inch to 2-1/4 inch. Measure the leaf before ordering, because the thru-bolt length is what the range governs.
11) What should be specified for a classroom door instead of an entrance lock?
The QCL200 series includes classroom and classroom SFIC functions alongside the entry/office function, so the same mechanical family covers it. Where a classroom security or intruder function with credential control is wanted instead, the TownSteel XCE-9000 Series is a Grade 1 heavy duty electronic classroom intruder cylindrical lockset with a keypad for doors 1-3/4 inch to 2 inch, and the Schlage XE360M is a Grade 1 wireless tubular lock in classroom/storeroom function for 1-3/4 inch doors with a smart mobile reader. Entrance function is not a classroom substitute, because it does not give the teacher a lockdown from inside.
12) Which lever styles are offered on the QCL200 series, and does the Sierra lever sag over time?
Three lever designs are built in the QCL200 series: E Sierra, M Summit and A Slate. This QCL250 is the Sierra. Lever sag is handled by heavy-duty torsion springs in the chassis rather than by the lever itself, so the return force is the same across all three styles. There is also a clutching mechanism, which lets the outside lever spin free when locked instead of transferring force into the chassis.
13) Is there a QCL200 lock that meets hurricane requirements in Miami-Dade?
The QCL200 series has a hurricane compliant option with a Miami-Dade N.O.A., and it uses the 3/4 inch throw latch rather than the standard 1/2 inch. It also meets the California State Reference Code (formerly Title 19, Fire Marshal). The hurricane build has to be called out on the order, since the 3/4 inch throw latch is the option and not what ships by default.
14) I need a keypad or electronic version of this lock instead of a keyed lever. What are my options?
The QCL250 is a mechanical keyed lever, not electronic. For keypad access on the same bored 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, fitting doors 1-5/8 to 1-7/8 inches. The TownSteel XCE-2000 is a Grade 1 heavy duty keypad classroom lockset for 1-3/4 to 2 inch doors. For credential-based access, the Schlage NDEB is a Grade 1 ENGAGE Series wireless lock with a Bluetooth Low Energy reader for 1-5/8 to 2 inch doors.
15) What is the closest Grade 2 entry lockset to the Dormakaba QCL250 if I want a different brand?
The Orca Hardware OCL250 is the nearest match: Grade 2, medium duty, Entrance function cylindrical lockset. On the Dormakaba side, the Dorma C853 is an entry keyed single cylinder lever in the C800 Series but steps up to Grade 1 with a 1-3/8 to 2-1/4 inch door range. For knob rather than lever, the Marks USA 110AB is a Grade 2 entrance knob lockset with a 2-3/8 inch backset in satin stainless. Do not substitute the Dorma C501 or CL701 here, those are dummy and passage trim with no keyed cylinder.
16) I need to lock the whole floor on one key system. Does the QCL200 series cover restrooms and closets too?
It does, and that is the case for standardizing a building on one series. Beyond this Entry/Office lock, the QCL200 range covers Privacy for restrooms and bedrooms, Passage for closets and corridors that never lock, Classroom, Storeroom, Corridor, Communicating and Single/Half Dummy for inactive leaves. Every one of them shares the same 2-1/8 inch cross bore prep and thru bolt pattern, so the door prep is identical across the floor and only the chassis function changes.
17) Is the QCL250 lever ADA compliant for a public building?
Yes. The QCL200 series meets ANSI A117.1, the accessibility code, which is what an ADA-compliant opening requires for operable hardware, and the Sierra is a lever rather than a knob, so it operates without grasping or twisting. It also holds ANSI/BHMA A156.2 Grade 2.
18) Can an electronic keypad lock replace a keyed QCL250 in the same door prep?
Several standalone electronic cylindrical locks cover the same opening type without a key. 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. The SDC E75 Series is a battery-powered electronic cylindrical lockset with keypad access control for doors 1-3/4 inch to 2-1/8 inch. The QCL250 is a mechanical keyed entrance lock and offers an SFIC option across its functions, so a site already standardized on small format cores can move between the two families.
19) What finishes does the Stanley Security QCL250 Sierra lever come in?
Five, and all five are stocked in the Entry/Office Sierra lever: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. 626 satin chrome is the usual match for existing commercial hardware, 613 for a darker residential or hospitality look. Exposed trim is pressure cast zinc plated to match the finish designation, so the lever and rose carry the same plating rather than a painted coat.
20) What is the alternative to a QCL250 dummy or half dummy lever on an inactive leaf?
The QCL200 series carries single/half dummy among its functions. Two peers cover the same trim-only role: the Dorma C501 is a Grade 2 single dummy trim keyless lever lockset from the C500 Series for doors 1-3/8 inch to 1-3/4 inch, and the Orca Hardware OCL2170 is a Grade 2 medium duty half dummy lever. A dummy has no latch, so it mounts to the face of the inactive leaf for pull only.
21) Which privacy lock pairs with a QCL250 entrance lock on the same job?
For the bed and bath doors in the same building, the Cal-Royal CAL20 is a Grade 1 extra heavy duty privacy lock from the Calypso Series with a door thickness range of 1-3/8 inch to 2 inch, and the Orca Hardware OCL240 is a Grade 2 medium duty privacy cylindrical lockset. The QCL200 series also lists privacy among its own functions, which keeps lever style and finish consistent across the unit if that matters more than mixing grades.
22) Does a mechanical pushbutton keyless lock replace a keyed entrance lever?
It changes how the door is credentialed. The Lockey 2830 is a mechanical pushbutton keyless knob lock with auto-locking passage function for doors 1-1/8 inch to 2 inch, 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 are knob trim, so an opening required to have an ADA lever needs the lever product; the QCL250 is ADA compliant under ANSI A117.1 with the Sierra lever.
