Stanley Security QCL170SIE626LC – Frequently Asked Questions

1) What does the QCL170 storeroom function actually do on the door?
The Stanley QCL170 is the storeroom function, ANSI F86. The outside lever stays locked at all times and is retracted by key only; the inside lever always retracts the latch for free egress. Nothing about it can be left unlocked by turning a button, which is why it is the usual choice for storage rooms, mechanical rooms and IT closets. If you want the ability to leave the door unlocked during the day, the entry/office QCL150 (ANSI F109) or corridor QCL154 (ANSI F90) are the functions to order instead.
2) Will the Stanley QCL100 lever fit my existing door prep and strike?
It uses the standard commercial prep: 2-1/8 inch diameter cross bore, 2-3/4 inch square backset latch, and a 1-1/8 x 2-1/4 inch latch faceplate. The strike supplied is the ANSI/ASA 1-1/4 x 4-7/8 inch type, so it drops into a frame already cut for ASA strikes. Door thickness range is 1-3/8 to 2 inches. Backsets of 2-3/8 and 5 inches are available if your bore centers do not match 2-3/4.
3) This QCL170 is less cylinder - what do I need to order with it?
Less cylinder means the lock ships without a keyed cylinder, so you supply one and key it into your existing system. Stanley also offers the QCL100 in factory keyways: BF (BEST), KW (Kwikset), WE (Weiser), SC (Schlage), GA (Yale) and LA (Sargent), with 6-pin brass cylinders and two keys per lockset. If your building runs small format interchangeable cores, order the SFIC version, QCL171, which is the same F86 storeroom function prepped for your existing SFIC cores.
4) What is the closest storeroom-function alternative to the Stanley QCL170 if I need a small format interchangeable core lock?
The Marks USA 175RF SFIC is a storeroom-function clutched lever lockset supplied less core with a 2-3/4 inch backset and ANSI strike, so it drops into the same door prep. The difference is grade: the Marks 175RF is certified Grade 2, while the Stanley QCL170 is Grade 1. If you want to stay Grade 1 and still use small format cores, stay inside the QCL100 series and order the QCL171 storeroom SFIC version instead.
5) I need a keyed lever for an office door where the latch should unlock with the inside button, not stay locked all the time. What should I use instead of the Stanley QCL170?
The QCL170 is storeroom function, ANSI F86, so the outside lever is always locked and requires a key. For an office door that you want to leave unlocked during business hours, the Dorma C853 is a Grade 1 entrance-function single cylinder keyed lever lockset for doors 1-3/8 to 2-1/4 inches thick. Another Grade 1 entry/office option is the Dorma C150 from the C100 series. Within Stanley's own range, the QCL150 entry/office function, ANSI F109, covers the same need.
6) Is the Marks USA 195RAB a direct substitute for the Stanley QCL170 storeroom lever?
Not for the same opening. The Marks USA 195RAB is a Grade 1 Survivor Series clutched lever supplied less core, which matches the QCL170 on grade and on the less-cylinder ordering approach, but it is entrance/office function while the QCL170 is storeroom, ANSI F86. Entrance/office allows the outside lever to be left unlocked; storeroom keeps it locked at all times. Match the function to the door before substituting.
7) If I want keypad access instead of a keyed storeroom lock, what replaces the Stanley QCL170?
Several Grade 1 electronic cylindrical locks cover the same cylindrical door prep. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic entrance lock with a digital keypad, 100 user codes, and IC/SFIC compatibility, for doors 1-5/8 to 1-7/8 inches. The TownSteel XCE-2000 is a Grade 1 heavy duty keypad lockset for doors 1-3/4 to 2 inches. The Schlage NDEB is a Grade 1 ENGAGE wireless lock with storeroom, office, privacy and apartment functions for doors 1-5/8 to 2 inches. Note the QCL100 series accepts 1-3/8 to 2 inch doors as standard, so verify your door thickness against the electronic model.
8) For a classroom intruder door, is the Stanley QCL170 the right lock or should I use something else?
The QCL170 is storeroom function and is keyed from the outside only, so it cannot be locked down from inside the room. For classroom security, Stanley offers the QCL168 classroom security function and QCL169 in SFIC within the same series. If the project calls for electronic intruder lockdown, the TownSteel FCE-4000 is an RFID electronic intruder classroom cylindrical lockset and the TownSteel XCE-9000 is a keypad electronic classroom intruder lockset, both Grade 1 heavy duty.
9) We already have BEST small format cores in the building. Which locks let us keep them?
The Stanley QCL100 series is built to retrofit existing small format cores, and it is offered with a BF-BEST keyway option along with an SFIC version of the storeroom function, the QCL171. On the electronic side, the BEST 9KZ EZ Series is an electronic keypad cylindrical lock with key override, and the Alarm Lock Trilogy T2 DL2700 is IC/SFIC compatible. All three let you carry your existing core program forward rather than rekeying the building.
10) Do I need to specify handing for a Stanley QCL100 lever lock?
No. All QCL100 series lever locksets are non-handed, so one lock covers left and right hand openings. That makes it simpler to stock a single part number across a building.
11) Is this lock heavy duty enough for a school corridor or other high traffic door?
The QCL100 series is BHMA/ANSI Grade 1 certified and tested to the Grade 1 requirement of 800,000 cycles. It uses a clutching mechanism so force on a locked outside lever spins free rather than breaking the internals, thru-bolt mounting, and heavy-duty torsion springs to stop lever sag. That is the construction package you want on abuse-prone openings.
12) What is a comparable Grade 1 storeroom or entry cylindrical lever if I cannot use the Stanley QCL170?
Among mechanical Grade 1 cylindrical levers, the Dorma C853 entry keyed lever (C800 Series, 1-3/8 to 2-1/4 inch doors) and the Marks USA 195RAB clutched entry lever from the Survivor Series are the closest peers. If you specifically need storeroom function and Grade 2 is acceptable, the Marks USA 175RF SFIC storeroom lever uses a 2-3/4 inch backset and ANSI strike like the Stanley. Note the 175RF is Grade 2, not Grade 1.
13) Should I use a mechanical storeroom lever or go with an electronic keypad lock?
A keyed storeroom lever like the QCL170 needs no batteries, no programming and no audit setup, which suits closets and back-of-house doors where a handful of keyholders is fine. If you need to change access without rekeying, or want a code and audit trail, Grade 1 standalone options include the Alarm Lock Trilogy DL2700 (100 user codes, IC/SFIC compatible, 1-5/8 to 1-7/8 inch doors) or the Schlage NDEB ENGAGE wireless lock, which offers storeroom, office, privacy and apartment functions on 1-5/8 to 2 inch doors. Watch the thinner door ranges on the electronics against the Stanley's 1-3/8 to 2 inches.
14) Can I keep my existing small format interchangeable cores when switching to Stanley QCL100 locks?
Yes, that is one of the reasons the series is specified on retrofits. Order the SFIC variants and drop your current small format cores straight in. For storeroom function that is the QCL171; classroom is QCL161, entry/office QCL151, corridor QCL155.
15) What should I use instead of the Stanley QCL170 on a restroom or bedroom door?
The QCL170 is a keyed storeroom lock and has no inside privacy button, so it is the wrong function for a restroom. For a Grade 1 privacy lever on doors 1-3/8 to 2 inches thick, the Cal-Royal CAL20 Calypso Series extra heavy duty privacy lock covers the same door thickness range the QCL100 series lists as standard. Stanley's own equivalent is the QCL140 privacy function, ANSI F76.
16) What is a simpler non-keyed lever to pair with the Stanley QCL170 on doors that do not need locking?
For unlocked openings on the same project, the Cal-Royal CAL30 Calypso Series is a Grade 1 passage lockset for doors 1-3/8 to 2 inches thick, and the Marks USA 195N Survivor Series is a Grade 1 ADA compliant passage lever. Both hold the Grade 1 rating the QCL170 carries. Stanley's matching passage function within the same series is the QCL130, ANSI F75, which keeps the lever design and finish consistent across the job.
17) Can I use an Orca OCL250 entrance lockset in place of the Stanley QCL170?
Only where the specification allows a lighter lock. The Orca OCL250 is a Grade 2 medium duty entrance cylindrical lockset, while the Stanley QCL170 is Grade 1 and tested to the Grade 1 standard of 800,000 cycles with a clutching mechanism and thru-bolt design for high traffic, heavy abuse openings. The functions also differ - entrance versus storeroom. On a stairwell, storage room, or mechanical room under a Grade 1 spec, the OCL250 will not meet it.
18) Is the Dorma C501 a substitute for the Stanley QCL170 lever?
No. The Dorma C501 is a Grade 2 single dummy trim keyless lever lockset for doors 1-3/8 to 1-3/4 inches - a fixed pull with no latch at all. The Stanley QCL170 is a Grade 1 keyed storeroom lock with a 1/2 inch steel latch bolt and ASA strike. Dummy trim is used on the inactive leaf of a pair or on a closet door. Stanley's own dummy in the same series is the QCL120.
19) Would a Kwikset 912TNL SmartCode lever work in place of the Stanley QCL170 on a commercial storeroom door?
They are not equivalents. The Kwikset 912TNL ZW500 SmartCode is a Z-Wave electronic Tustin lever, keyed one side, for doors 1-3/8 to 2 inches. The Stanley QCL170 is a Grade 1 commercial storeroom lock built to 800,000 cycles with a clutching mechanism and thru-bolt design for high traffic, heavy abuse applications. If the opening is under a commercial spec and you want electronic access, look at a Grade 1 electronic cylindrical lock such as the Alarm Lock T3 DL3075 rather than the residential-style Kwikset.
20) What is the lowest-cost way to get keyless entry on a storeroom door without wiring, compared with the keyed Stanley QCL170?
The QCL170 requires a cylinder and keys - it ships less cylinder and takes a 6-pin brass cylinder in BEST, Kwikset, Weiser, Schlage, Yale or Sargent keyways. For a code-only approach with no wiring and no keys to issue, the Lockey 1600 is a heavy duty mechanical keyless knob lock with adjustable backset for doors 1-1/8 to 2 inches, and the Lockey 2830 is a mechanical pushbutton keyless knob lock with auto-locking passage function. Both are knob trim rather than lever, which matters if the opening needs ADA lever operation.
21) Can the Stanley QCL170 be used on a fire rated door?
The QCL100 series is built with fire-rated latches, and a hurricane compliant option is offered in the series. Confirm the specific latch option on your order matches the label on your opening.
22) What finish does this Stanley QCL170 lever come in, and what is the trim made of?
It is supplied in 626 satin chrome. Exposed trim is pressure cast zinc, plated to match the finish designation, with concealed mounting screws so no fasteners show on the rose.
23) How far does the latch bolt throw on the Stanley QCL100 lock?
The keyed exterior latch is a 1/2 inch steel bolt, and the interior side uses a 1/2 inch spring latch. That is a standard cylindrical throw, so it engages an ASA strike cut to the usual 1-1/4 x 4-7/8 inch frame prep without shimming.
