Schlage Residential F51A LAT 626 – Frequently Asked Questions

1) Will the Schlage F51A Latitude lever entry lock fit a 1-3/8 inch door, and do I have to pick a backset when I order?
Door thickness range on the F51A is 1-3/8 to 1-3/4 inches, so it covers both the standard 1-3/4 inch entry door and the lighter 1-3/8 inch interior door found in older houses. Backset is not an ordering decision: the lock ships with a dual backset latch that sets to either 2-3/8 or 2-3/4 inches, which are the two backsets used on North American bored doors. Door prep is a 2-1/8 inch cross bore through the face and a 1 inch edge bore for the latch.
2) I'm swapping out a worn knob lock on a rental unit door. Will the Schlage F51A go into the holes that are already there?
If the door carries a standard bored prep it will. The F51A wants a 2-1/8 inch cross bore and a 1 inch edge bore, which is the same prep used by ordinary knob locks. The latch faceplate is 1 x 2-1/4 inches with 1/4 inch radius corners, so it seats in a mortise already cut for a radius corner face of that size; a square corner mortise has to be re-cut or filled. A circular drive-in latch is included too, so a door bored for a drive-in latch with no faceplate mortise at all is handled without touching the door edge. The lock is non-handed, so the same part works on a left or right hand door.
3) Will the F51A lever lock latch into the strike plate already in my door frame?
Throw on the F51A dead latch is 1/2 inch, and the strike supplied with it is a full lip radius corner strike measuring 2-1/4 x 1-5/8 inches with no box behind it. A frame already cut for a radius corner strike of that size takes the new strike directly. If the frame has a square corner strike, a box strike, or a full lip strike of a different length, the frame mortise is a different cut and either the old strike stays in place or the frame gets reworked. Worth checking before the truck rolls, because the frame is the part you cannot swap in five minutes.
4) How does the Schlage F51A entry lock actually lock and unlock day to day?
It is a single cylinder keyed entry lock: key outside, turnbutton inside, no key needed from the inside. Turning the interior turnbutton locks the outside lever, and the lock releases when the door is opened from the inside so anyone inside can get straight out. From outside you lock or unlock it with the key. In ANSI terms this is the F81 entrance function, which is the one spec writers call for on apartment and unit entry doors where free egress matters.
5) Can a Schlage F51A lever go on a fire rated corridor or unit entry door?
The F51A is one of the F Series functions available UL Listed for 3-hour fire doors, along with F10, F40 (CSV only) and F80. It is certified to ANSI/BHMA A156.2-2017 Commercial Grade 2 and ANSI/BHMA A156.39-2015 Residential Grade AAA. For a rated opening, order the UL Listed version specifically and match it to the door's own label, since the label governs what the opening will accept.
6) Can I get a whole building of Schlage F51A locks running on one key?
The cylinder is a 5-pin C keyway, Schlage's standard residential keyway, and the lock is supplied in a keyed alike (KA4) configuration with two 5-pin C section keys per lock. Keying alike only works across cylinders sharing the same keyway, so F51A units group cleanly with other C keyway hardware in the same key plan. For a property manager running a fleet of unit doors, that is the difference between one key on the maintenance ring and thirty.
7) Does the Schlage F51A entry lever include a deadbolt, or do I need to add one?
No deadbolt. The F51A is a bored lever lock with a 1/2 inch throw dead latch, which resists carding but is not a deadbolt, and there is no second bore in its prep for one. If the opening needs a deadbolt above the lever, ZenSupply carries the Delaney Traditional 200-B and the Delaney Contemporary 200-LTR, both Grade 3 single cylinder deadbolts with a key outside and a thumbturn inside. Budget for a second cross bore in the door if there isn't one already.
8) What is the closest Grade 2 keyed entry alternative to the Schlage F51A Latitude lever lock from another brand?
The Delaney Katana 400-KA is the nearest match on rating and keying: it is a Grade 2 single cylinder handleset with interior trim, the same ANSI/BHMA Grade 2 and the same single cylinder arrangement carried by the Schlage F51A Latitude lever. What separates them is the form of the device. The F51A is a cylindrical bored lockset with the Latitude lever on both faces, keyed on the outside and controlled by a turnbutton on the inside. The Katana is a handleset, so the exterior of the door gets a grip and plate and the inside gets separate trim. If the goal is a lever on both sides at Grade 2, the F51A is the direct answer; if the opening is being dressed with a full exterior handleset at the same grade, the Katana 400-KA is the peer to order.
9) Will a Delaney single cylinder deadbolt do the same job as the Schlage F51A entry lock?
No, and they are usually specified together rather than one instead of the other. The Delaney Traditional 200-B and the Delaney Contemporary 200-LTR round deadbolt are both Grade 3 single cylinder deadbolts with a cylinder by thumbturn function, meaning a key outside and a thumbturn inside with no handle and no latch that holds the door closed. The Schlage F51A is a Grade 2 cylindrical lockset that carries the Latitude lever and the 16-086 dead latch, so it both latches the door and locks it, with the key outside and the turnbutton inside. On an entry door that wants a deadbolt above a keyed lever, the F51A handles the operating and latching function while a 200-B or 200-LTR handles the deadbolting; ordering only the deadbolt leaves the door with nothing to work the latch.
10) What lever lock should I use instead of the Schlage F51A on a door that needs credential access rather than keys?
The Paxton PaxLock Pro 900-620WT-US in the Galaxy lever latch style is the credential-based counterpart. It is a battery powered lever latch lock with a dual frequency reader running 13.56 MHz and 2.4 GHz with Bluetooth and AES128 encryption, listed to ISED, UL, and FCC, and supplied in white. The Schlage F51A is a mechanical device with no electronics, keyed on the outside with a turnbutton on the inside. Both give a lever on the door, so the decision is whether the opening needs to be managed by credential and audit or by cut key. A common split in multi-family and light commercial work is PaxLock Pro on the doors that need access revoked remotely and the F51A on the unit or interior doors that stay on keys.
11) Is the Schlage F51A lever handed? I have doors swinging both ways in the same building.
Non-handed. One F51A covers left hand and right hand doors, inswing or outswing, so a property manager or contractor stocking spares does not have to hold two versions or measure the swing before ordering. The dual backset latch works the same way, adjusting to 2-3/8 or 2-3/4 inches rather than being fixed at one.
12) Is the Schlage F51A tough enough for a rental with heavy tenant turnover, or should I be buying commercial hardware?
The F51A is certified Grade 2 under ANSI/BHMA A156.2-2017, the mid commercial tier, and Grade AAA under the residential standard A156.39-2015, which is the top residential tier. Construction is a zinc and steel substrate. That puts it a step above the Grade 3 residential sets ZenSupply also carries, such as the Callan Visconti and Callan Briona handlesets, which is the level most builder-grade hardware sits at. For apartment and condo unit doors, multi-family corridors and rental turnover, Grade 2 is the level that holds up.
13) What finishes and rose styles come on the Schlage F51A Latitude lever? I need it to match hardware already hanging in the building.
Seven finishes: 608 satin brass, 618 bright nickel, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome and 716 aged bronze. Five rose designs on the Latitude lever: Kinsler, Addison, Century, Collins and Greenwich. Every finish is offered with every rose, 35 combinations in total, so the rose shape and the finish are independent choices. If part of a floor is already done, match the rose first, then the finish code, and the new units read as the same set.
14) I want a gripped handleset on the front entry instead of a lever. What are the alternatives to the Schlage F51A?
The F51A is a bored lever set, so the exterior trim is a lever, not a thumb-latch grip. For a handleset on the same kind of residential entry, ZenSupply carries the Bravura 973-Montgomery, Grade 2, with a 672 interior plate and a 939-Charlotte interior lever if you want to keep a lever inside. Bravura also offers the 913-Savannah, 915-Jacksonville and 971-Austin, all Grade 2, each with a 615 interior plate and a 906-Macon interior knob. The Delaney Katana 400-KA is another Grade 2 single cylinder handleset with interior trim; the Delaney Avino and the Callan Visconti and Briona sit at Grade 3.
15) Is there a keycard or credential version of this style of entry lever, or is the F51A mechanical only?
Mechanical only. The F51A works on a key and an interior turnbutton with no electronics in it. If the opening needs credentials instead of keys, ZenSupply carries the Paxton PaxLock Pro Galaxy lever latch lock, a battery powered lever with a dual frequency 13.56 MHz and 2.4 GHz reader, Bluetooth and AES128. One fit difference decides it on older doors: the PaxLock Pro is specified for 1-3/4 inch door thickness, while the F51A covers 1-3/8 through 1-3/4 inches, so a thin 1-3/8 inch door rules the electronic lever out.
16) What comes in the box with the Schlage F51A, or do I need to order the latch and strike separately?
Latch and strike are both included. The latch is a dual option dead latch that can go in round with a faceplate or as a circular drive-in, and it adjusts to 2-3/8 or 2-3/4 inch backset. The strike is a full lip radius strike, 2-1/4 x 1-5/8 inches, with no box. Two 5-pin C section keys come with the lock. What is not in the box is a deadbolt or any frame reinforcement, so a job that calls for either needs those ordered alongside.
17) Which Grade 2 alternative to the Schlage F51A keeps a lever on the inside of the door instead of a knob?
The Bravura 973-Montgomery handleset is the one that does. It comes with a 672 interior plate and a 939-Charlotte interior lever at Grade 2. The other Bravura Grade 2 handlesets take a knob on the inside instead: the 913-Savannah, the 915-Jacksonville, and the 971-Austin all pair a 615 interior plate with the 906-Macon interior knob. The Schlage F51A carries the Latitude lever at Grade 2 and is levered on both faces. For a building being standardized on lever operation at every hand position, the F51A and the Bravura 973-Montgomery are the two Grade 2 devices in the set that give a lever to the person on the inside.
18) What are the Grade 3 keyed entry options if I do not need the Grade 2 rating of the Schlage F51A?
Three single cylinder devices in the comparable range sit at Grade 3: the Callan Visconti 374001 handleset with interior trim, the Callan Briona 374107 handleset with interior trim, and the Delaney Avino 400-AV handleset with interior trim. All three are keyed entry devices for an exterior door and all three put a handleset grip on the outside face. The Schlage F51A Latitude lever is rated ANSI/BHMA Grade 2 and is a bored cylindrical lockset with a lever rather than a grip. Where a specification or a house standard calls out a Grade 2 keyed entry lever, the F51A meets it and the Grade 3 handlesets are a different rating; where the grade is open and the door is getting a handleset look, the Callan and Delaney models are the ones to price out.
19) Can a Bravura or Callan handleset be swapped straight onto a door that currently has a Schlage F51A lever?
They are not the same device even though both are keyed entry hardware for an exterior door. The Schlage F51A is a cylindrical bored lockset with a Latitude lever on both faces, working with the 16-086 dual option dead latch and the 10-027 full lip radius strike measuring 2-1/4 by 1-5/8 inches. The Bravura 913-Savannah, 915-Jacksonville, and 971-Austin are handlesets that put a grip and plate on the exterior and a 615 interior plate with a 906-Macon knob on the inside; the Callan Visconti 374001 and Briona 374107 are single cylinder handlesets with interior trim. Going from the F51A to any of those changes the exterior of the door from a lever to a handleset grip and changes the interior trim along with it, so treat it as a hardware change on the opening rather than a like for like replacement.
20) I have 1-3/8 inch thick doors in the building. Which of these lever locks covers that thickness?
The Schlage F51A Latitude lever covers a door thickness range of 1-3/8 to 1-3/4 inches, so it takes the thinner doors and the standard 1-3/4 inch exterior doors on the same order. The Paxton PaxLock Pro 900-620WT-US lever latch lock is specified for 1-3/4 inch door thickness. On a mixed building where some units are hung with 1-3/8 inch doors, the F51A is the device that spans both, and it is non-handed, so the same lock goes on left hand and right hand openings without ordering separate parts. Confirm the actual thickness at a few doors before committing the quantity, since older stock doors vary.
21) What is the difference between a keyed entry lock like the Schlage F51A and a passage set?
A keyed entry lock secures the opening; a passage set only holds the door shut. The F51A takes a key on the outside and has a turnbutton inside, so the outside lever can be locked. A passage product like the Emtek Select Brass Conical Stem Dark Walnut Knob is passage, hall and closet function: it latches, it turns from both sides, and there is nothing to lock. Passage belongs on a bedroom, hall or closet door, never on a unit entry or an exterior opening.
22) What goes on the closet and hall doors if the entry door is getting a Schlage F51A?
Those openings take a passage device, not a keyed one. The Emtek Select Brass Conical Stem Dark Walnut Knob is built in the passage function for hall and closet doors, so it latches the door and turns from either side with no cylinder and no key. The Schlage F51A is a keyed entry device, single cylinder, with the key outside and the turnbutton inside, which is what an entry door wants and what a closet door does not. Note the trim difference when specifying: the Emtek passage device is a knob, while the F51A carries the Latitude lever, so a job standardized on lever operation throughout will want to check that before ordering the interior doors.
23) What is the difference between the Delaney Katana and Avino handlesets when cross-referencing against a Schlage F51A?
They are two different grades within the same Delaney handleset family. The Katana 400-KA is a Grade 2 single cylinder handleset with interior trim; the Avino 400-AV is a Grade 3 single cylinder handleset with interior trim. Both are keyed single cylinder devices for an exterior door. The Schlage F51A is model F51A in the F Series, a Grade 2 single cylinder cylindrical lockset in zinc and steel. When cross-referencing a Schlage F51A line item to Delaney, the Katana 400-KA is the one that matches on grade and keying, and the Avino 400-AV is the Grade 3 model in the same series family; the exterior trim on both is a handleset rather than the F51A lever.
