Sargent 10XG37-LB-26D-LC – Frequently Asked Questions

1) Will the Sargent 10X Line cylindrical lock fit a 1-3/8 inch door?
Yes. The 10X Line bored lock covers door thickness from 1-3/8 inches up to 2 inches, so it handles both older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors without a special order.
2) How does a classroom function lock actually work day to day?
On the 10XG037 classroom function, the outside lever is locked and unlocked by key only. There is no pushbutton or thumbturn on the inside, so a student cannot lock the room from within. The inside lever always retracts the latch for free egress. That is the difference from a classroom security function, which adds an inside keyed cylinder so a teacher can lock the outside lever from inside the room without stepping into the corridor.
3) Is the Sargent 10X Line lock fire rated for a labeled classroom door?
Yes. The 10X Line cylindrical lock is UL-cUL fire rated up to 3 hours, and it is also Florida Building Code approved, ADA compliant, and windstorm certified. That covers the usual specification package for a school corridor or a stair door in a hurricane zone.
4) We use Schlage C keyway across the building - is the Sargent 10XG037-LC still an option?
The Sargent 10XG037-LC lockbody accepts all cylinder formats from fixed to interchangeable core and all SARGENT key systems, and it ships less cylinder so the cylinder is specified separately. If the facility standard must stay on a 6-pin Schlage C keyway, the Cal-Royal AG03 classroom lever is supplied with a 6-pin Schlage C keyway keyed different on a 2-3/4 inch backset, and the Arrow MK33-BD-CS asylum function lock uses a conventional Schlage C keyway cylinder.
5) What is the closest Grade 1 classroom lever lock to the Sargent 10XG037-LC from another manufacturer?
The Dexter C1000 Series classroom cylindrical lever lock is the nearest equivalent: it is a Grade 1 keyed classroom function cylindrical lever with a clutching lever, listed for doors 1-3/8 inch to 1-3/4 inch thick. The Sargent 10XG037-LC is also Grade 1 classroom function with a lever handle, and covers door thickness from 1-3/8 inch to 2 inch with backsets from 2-3/8 inch to 5 inch, so it reaches thicker doors and a wider backset range than the Dexter.
6) Is there a lower-cost classroom lever if a Grade 1 lock is more than the opening needs?
The Cal-Royal AG03 is a classroom function lever in the AG Series, built to Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/4 inch backset. It is a lighter-duty alternative to the Sargent 10XG037-LC, which is a Grade 1 heavy duty cylindrical classroom lock tested at 20 million cycles and accepting all SARGENT key systems from fixed cylinders to interchangeable core.
7) We need lockdown capability from inside the classroom - is the 10XG037-LC the right function?
No. The Sargent 10XG037-LC is a classroom function lock, keyed from the outside only with a single cylinder, so the outside lever is locked and unlocked by key from the corridor side. If teachers must secure the door from inside the room, the Dexter C1000 Series classroom security lever is the function to specify - it is a Grade 1 keyed classroom security cylindrical lever with clutching, for doors 1-3/8 inch to 1-3/4 inch thick.
8) Is this Sargent lock handed, and do I need to specify left or right?
Non-handed. The 10X Line cylindrical lever lock installs on either hand of door without field reversing, so a property manager stocking spares only has to carry one part number for the whole building.
9) Does the Sargent 10XG037-LC work as an electrified lock, or do I need a different model?
The 10XG037-LC is a mechanical classroom cylindrical lock; its EcoFlex technology is cited for up to 92 percent energy savings on electromechanical functions such as Wave to Open, Request to Exit and Door Position Switch. If the opening calls for a dedicated electrified cylindrical lever, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12V AC/DC for doors 1-3/4 inch to 2 inch thick.
10) For the corridor and closet doors that do not need to be keyed, what pairs with the Sargent 10XG037-LC?
Keep the Grade 1 level and drop the keying: the Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, for doors 1-3/8 inch to 2-1/4 inch thick, and the Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet cylindrical lever, fire rated, for 1-3/4 inch to 2 inch doors. The Sargent 10XG037-LC itself is keyed classroom function and non-handed.
11) What is the difference between the Sargent 10XG037-LC and a storeroom lever like the Hager 2580?
Function. The Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for doors 1-3/8 inch to 2 inch, and storeroom keeps the outside lever locked at all times with the key retracting the latch for entry. The Sargent 10XG037-LC is a Grade 1 classroom lock, where the key locks and unlocks the outside lever so the room can be left in a free-passage state during class. The Cal-Royal AG05 is another storeroom option, Grade 2 with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors.
12) Is a keypad leverset a substitute for a keyed classroom lock like the Sargent 10XG037-LC?
Not for the same duty. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function, fitting doors 1-1/8 inch to 2 inch, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. Neither is classroom function keyed to a master system. The Sargent 10XG037-LC is a Grade 1 single cylinder classroom lock whose lockbody accepts all cylinder formats from fixed to interchangeable core and all SARGENT key systems.
13) What should I use instead of the Sargent 10XG037-LC on a patient or utility room that needs no inside release?
Asylum function is the one to look at. The Dexter C1000 Series asylum lock is Grade 1 asylum/institution/utility function for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum lock with a ball knob. The Sargent 10XG037-LC is classroom function with a lever handle, which leaves the inside lever always free to exit.
14) What lever and rose options does the Sargent 10XG037 come in?
Two trim combinations are built: the L lever with L rose, and the B lever with L rose, both in 26D satin chromium plated over nickel. If you are matching existing openings in a building, the lever style is the piece to confirm, since both share the same L rose.
15) Is there an antimicrobial option for the Sargent 10X lever in a healthcare setting?
Yes, an optional Microshield antimicrobial coating is available on the 10X Line for healthcare, education, and other environments where surface contamination is a concern. It has to be specified when ordering rather than added later.
16) Can I match the Sargent 10XG037-LC lever on a door that needs no latch at all?
A dummy trim is the part for a non-latching leaf. The BEST 9K Series 1DT single dummy trim is a Grade 1 heavy duty non-keyed cylindrical lever dummy, and the Accentra 455LN Augusta is a Grade 1 heavy duty single dummy cylindrical lever in the 5400 Series. Both hold the Grade 1 level of the Sargent 10XG037-LC but have no lockbody or cylinder, so they cannot be keyed into a classroom keying scheme.
