Schlage A79PD TUL 626 – Frequently Asked Questions

1) What does the Schlage A79 communicating lock function actually do?
The A79 is a keyed cylindrical knob lock that is locked or unlocked by key from the outside, with a blank plate on the inside face instead of a knob. There is no inside trim to grab, so the door is operated only from the key side. That makes it a controlled-access opening, not a normal two-sided door.
2) Is the Schlage A79 handed, or do I need to specify left or right?
Non-handed, so one part covers both swings and you do not specify a hand when ordering. That also means a property manager can stock a single A79 for every opening in a building regardless of which way the doors swing.
3) Will a Schlage A79 fit my existing 2-3/8 inch backset door prep?
The A79 is built on a 2-3/8 inch backset and ships with the 11-085 deadlatch, a square corner latch with a 1 x 2-1/4 inch face. If your door is bored at 2-3/8 inches from the edge to the center of the cross bore, it drops in. Doors bored at 2-3/4 inches, the other common commercial backset, need a 2-3/4 inch latch instead.
4) What strike comes with the Schlage A79 and will it match my existing frame cutout?
The standard strike is the 10-001, a 1-1/8 x 2-3/4 inch square corner T-strike with a 1-1/8 inch lip and a box. Most hollow metal frames are prepped for that footprint, so it lands in the existing cutout on a like-for-like replacement. If your frame has a round corner or an ANSI 4-7/8 inch strike prep, order the matching strike option rather than forcing this one.
5) Can a Schlage A79 be used on a fire rated door?
Yes. The A Series cylindrical locks are UL listed for 3-hour fire doors, and UL/cUL listed for A label single doors up to 4 by 8 feet. The letter F and the UL symbol stamped on the latch front are what identify a listed latch, so an inspector checking the opening looks at the latch face.
6) The drawing calls for a Grade 1 storeroom knob lock instead of the Schlage A79 - what covers that?
The Schlage A79 is tested and certified under ANSI/BHMA A156.2, Series 4000 Grade 2 and is listed heavy duty. If the spec is written to Grade 1, the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet knob lock with a single cylinder from the 8X Line Series, carrying a 2-3/4 inch backset rather than the A79's 2-3/8 inch. The BEST 8K Series is also a Grade 1 heavy duty knob lock with a single cylinder, but it is listed in an entrance function rather than storeroom, so it is a grade match and not a function match.
7) Should I order the A79 with a cylinder or less cylinder?
Two cylinder choices. The P option is a conventional 6-pin cylinder in the C keyway, ready to use out of the box and supplied with 2 keys. The L option is less conventional cylinder, meaning the lock arrives without one so a locksmith can fit the building's own cylinder into an existing masterkey system. If you already run a keyway across the site, take L. If this is a one-off opening, take P.
8) Can I key a Schlage A79 into the master key system I already have on my Schlage locks?
The A Series accepts all Schlage standard, removable core, and high security cylinders, so an A79 keys into an existing Schlage system. Keyed functions come standard in Everest 29 keyways. If your facility needs a UL437 listed cylinder, that is an option and you specify a Primus XP 20-500 Series cylinder.
9) What knob designs and finishes does the Schlage A79 come in?
Four knob designs are offered on the A79: Orbit, Georgian, Levon, Plymouth, and Tulip trim also appears in the range. Finishes run 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 625 Bright Chrome, 626 Satin Chrome and 643E Aged Bronze. Pick the design and finish already on the rest of the building and the A79 matches the adjacent openings even though it functions differently.
10) Does the Schlage A79 meet ADA and Buy American requirements for a government or institutional job?
Both are stated. The A Series meets ADA requirements and meets the Buy American Act. On the California Referenced Standards Code, all levers with a return to door of 1/2 inch or less comply. Note that the A79 is a knob, not a lever, so if your jurisdiction requires lever operation for accessible openings you need a lever product rather than this knob.
11) I need a keyed knob lock but I want a knob on the inside too. Is the A79 the wrong choice?
Yes, the A79 is the wrong choice for that. It carries a blank plate on the inside, so there is nothing to turn from the room side. For an opening that stays locked outside but is always free to exit from the inside, order the A80 storeroom lock instead. For a keyed opening where the inside knob has a button, look at the A53 entrance lock.
12) What knob lock from another brand is the closest match to the Schlage A79 for a keyed storeroom opening?
The Schlage A79 is a Grade 2 cylindrical knob lock with a storeroom function and a single cylinder, locked or unlocked by key from outside with a blank plate inside, on a 2-3/8 inch backset at a heavy duty level. The closest like-for-like from another brand is the Sargent 6G04, a Grade 2 storeroom/closet knob lock with a single cylinder in the 6 Line Series, listed at a standard duty level. The functional split to check before you swap is the inside face: the A79 carries a blank plate on the inside rather than an operating knob, so confirm what the opening needs on the room side.
13) What should I use instead of the A79 on an interior office or classroom door that needs a keyed knob?
The A79 with its blank inside plate suits a closet, utility room, or equipment room, not an occupied room. For a classroom, the A70 classroom lock in the same A Series keeps the trim and finish consistent. Cross-brand, the Dexter C2000 Series Grade 2 classroom ball knob and the Corbin Russwin CK4851 Grade 2 entrance/office knob are both keyed cylindrical options that fit 1-3/8 to 1-3/4 inch and 1-3/8 to 2 inch doors respectively.
14) Is the Schlage A79 the same as the residential Schlage knobs sold at hardware stores?
No. The A79 is a commercial cylindrical lockset in the A Series, ANSI/BHMA A156.2 Grade 2, heavy duty, with a 2-3/8 inch backset and a fixed function. Schlage's residential line is a different product, for example the F Series F500 Plymouth with Georgian knob combo pack, which comes with adjustable backsets and dual strikes for 1-3/8 to 1-3/4 inch doors. They are not interchangeable parts and do not share the same commercial certifications.
15) Do I need to order a separate latch and strike with the Schlage A79?
No, the A79 ships with a latch and strike as standard: the 11-085 deadlatch on a 2-3/8 inch backset with a square corner 1 x 2-1/4 inch face, and the 10-001 square corner T-strike measuring 1-1/8 x 2-3/4 inches with a 1-1/8 inch lip and box. Numerous other latch and strike options are available if your frame prep or lip length differs. Keyed versions come with 2 keys.
16) My doors are already bored for a 2-3/8 inch backset - which knob locks match and which do not?
The Schlage A79 is built on a 2-3/8 inch backset and ships with the 11-085 deadlatch, a 2-3/8 inch backset square corner latch measuring 1 inch by 2-1/4 inch, so it drops into that prep directly. Two knob locks in the same class are dimensioned differently: the Sargent 8XG04 storeroom knob lock is listed with a 2-3/4 inch backset, and the Falcon W101 Grade 2 cylindrical knob lock is listed with a 2-3/4 inch backset as well. On the residential side, the Schlage F500 Plymouth with Georgian knob combo is listed with adjustable backsets and dual strikes, so it covers either prep.
17) I searched storeroom knob and got the Imperial ED-BKL580 alongside the Schlage A79 - are they interchangeable?
No, they mount to different things. The Schlage A79 is a cylindrical bored lockset that goes through the door prep and takes the 10-001 T-strike, a 1-1/8 inch by 2-3/4 inch square corner strike with a 1-1/8 inch lip and box. The Imperial USA ED-BKL580 is knob trim in a storeroom function from the ED-500 Series - trim that mounts to an exit device, not a bored lock. The same distinction applies to the Sargent 28C-KNOB, which is exit device trim with a knob and rose for 1-3/4 inch doors, and the Sargent 78-2875, which is an outside knob only with B design from the 7800 Series. If the door has an exit device on it, you want trim; if it has a 161 style bored prep, you want the A79.
18) Which Grade 2 knob locks look like the Schlage A79 but will not take a key?
The Schlage A79 is keyed with a single cylinder and comes with 2 keys. Several Grade 2 cylindrical knob locks that sit in the same size and grade class are non-keyed and will not accept a cylinder: the Arrow MK01 is a Grade 2 passage knob lock listed non-keyed in the MK Series, the Corbin Russwin CK4410 is a Grade 2 passage/closet cylindrical lock with a global knob listed non-keyed in the CK4400 Series, and the Falcon W101 is a Grade 2 cylindrical knob lock in a passage/closet latch function. Those are latch-only openings. If the room has to stay secured, stay with the keyed A79.
19) I need the inside of the door to lock too - what should I use instead of the Schlage A79?
The Schlage A79 is locked or unlocked by key from outside and carries a blank plate inside, so there is nothing to operate on the room side. If someone inside needs to secure the door, look at entrance and entrance/office functions: the Dexter C2000 Series is a Grade 2 keyed entry/office cylindrical ball knob lock, the Corbin Russwin CK4851 is an entrance/office cylindrical lock with a global knob and a conventional cylinder covering doors 1-3/8 inch to 2 inch thick, and the Callan Edgewood and Callan Sawyer are Grade 2 entrance knobsets. All four put an operating knob on the inside face that the A79 does not have.
20) The opening is a classroom door, not a storeroom - what takes the place of the Schlage A79?
The Schlage A79 is a storeroom function lock, keyed from the outside with a blank plate inside. For a classroom function in the same knob format from another brand, the Dexter C2000 Series offers a Grade 2 classroom cylindrical ball knob lock, keyed and non-clutching, covering doors 1-3/8 inch to 1-3/4 inch thick. Classroom and storeroom behave differently at the key, so match the function to how the room is meant to be controlled before ordering either one.
21) Is there a lighter-grade keyed knob lock than the Schlage A79 for interior units?
The Schlage A79 is a Grade 2 commercial knob lock at a heavy duty level. Keyed knob locks a grade below include the Cal-Royal BER00, a Grade 3 entrance/office knob lock for doors 1-3/8 inch to 1-3/4 inch thick, the Pamex FTF Baron, a Grade 3 knob lockset in an entrance/office function over the same thickness range, and the Master Lock BC Series BC01, a Grade 3 keyed entry biscuit knob. Each of those is an entrance or entrance/office function, which locks from the inside, rather than the A79's storeroom function keyed from outside with a blank plate inside.
22) We are hardware-scheduling fire-rated openings - how does the Schlage A79 line up against other knob locks on fire listing?
The Schlage A79 is UL listed for 3-hour fire doors and UL/cUL listed for A label single doors up to 4 feet by 8 feet, with the letter F and the UL symbol on the latch front indicating the listing. Among comparable knob locks, the Falcon W101 and the Falcon X101 both carry a fire rating: the W101 is a Grade 2 medium duty knob lock and the X101 is a Grade 1 heavy duty knobset with an interchangeable core covering doors 1-3/8 inch to 2-1/4 inch thick. Both Falcon models are passage function, so on a fire-rated opening that also has to be keyed and secured, the A79's storeroom function is the one that matches.
23) We are trying to get away from issuing keys for storage rooms - what replaces a Schlage A79?
The Schlage A79 is a keyed single cylinder lock supplied with 2 keys, and it accepts Schlage standard, removable core and high security cylinders, with cylinder functions coming standard in Everest 29 keyways. If you would rather run a code than a key, the Lockey 3830 is a mechanical keyless combination knob lock covering doors 1 3/16 inch to 2 inch thick. Read the function before you commit: the 3830 is listed as a passage function with auto-locking, while the A79 is a storeroom function locked or unlocked by key from outside with a blank plate inside.
24) We key our buildings on one system - how does the Schlage A79 cylinder compare to other keyed knob locks?
The Schlage A79 fits all Schlage standard, removable core and high security cylinders, and its keyed functions come standard in Everest 29 keyways, with a UL437 listed cylinder available by specifying a Primus XP 20-500 Series cylinder. It is ordered either with a conventional 6-pin C keyway cylinder or less the conventional cylinder if you are supplying your own core. Among comparable keyed knob locks, the Corbin Russwin CK4851 entrance/office cylindrical lock is listed with a conventional cylinder, and the Falcon X101 knobset is listed with an interchangeable core. Those are separate key systems, so a mixed order means more than one key way to manage.
