Schlage Residential F51A BEL 626 – Frequently Asked Questions

1) Will the Schlage F51A bell knob entry lock fit a 1-3/8 inch door, or is it only for 1-3/4?
Both. The F51A knob lock covers a door thickness range of 1-3/8 to 1-3/4 inches out of the box, which is the older interior/lighter exterior door and the standard commercial thickness. No spacer kit or thickness option to specify.
2) I don't know the backset on my door. Do I have to measure before ordering the Schlage F51A?
Not for this one. The F51A ships with a dual backset dead latch (Schlage 16-086, round and drive-in options included) that adjusts to either 2-3/8 or 2-3/4 inches, the two backsets you'll find on residential doors. Measure from the door edge to the center of the bore if you want to be sure, but either answer works.
3) Does a Schlage F51A knob lock need to be ordered left or right hand?
No handing to specify. The F51A is non-handed, so the same lock goes on a left or right hand door, inswing or outswing. That is why it works as a fleet stock item for a property manager who doesn't want to track handing across a building.
4) Will the F51A latch drop into the strike plate already in my door frame?
Likely yes if the existing prep is a standard residential cylindrical one. The F51A latch has a 1 x 2-1/4 inch faceplate with 1/4 inch radius corners, 7/8 inch housing diameter and a 1/2 inch throw, and it ships with a matching 1-5/8 x 2-1/4 inch full lip radius corner strike (Schlage 10-027). If your frame has a square corner faceplate mortise, the radius plate won't sit in it without chiseling the corners, and the included drive-in latch option can be used where there is no faceplate mortise at all.
5) What does the F51A keyed entry function actually do when someone locks up?
It's a single cylinder entry knob. From outside, key in and turn the cylinder to lock or unlock. From inside, the turnbutton in the knob locks it manually, and opening the door from the inside releases the button so nobody locks themselves out on the way through. There is no key required on the interior side.
6) Can I get a batch of Schlage F51A knob locks all on the same key?
Yes. Keying is a required selection: keyed different (the standard), keyed alike for a set that all take one key, or no cylinder at all if you're supplying your own. There's also an optional key code field if you need the locks cut to an existing code so they work with keys already in the building. The cylinder is 5-pin C keyway with two keys per lock.
7) Is a Schlage C keyway lock going to work with the keys I already have in my building?
If your existing Schlage locks are C keyway (the standard Schlage residential section), the F51A's 5-pin C keyway cylinder can be keyed to match, and there's a key code field on the order for exactly that. If your building runs a different manufacturer's keyway, or a restricted section, the C keyway cylinder won't accept those keys and you'd be starting a second key system.
8) What is the closest Grade 2 keyed entry alternative to the Schlage F51A bell knob if the front door needs a handleset instead of a knob?
The Delaney Katana is a Grade 2 single cylinder handleset with interior trim, so it holds the same ANSI/BHMA Grade 2 rating as the Schlage F51A bell knob entry lock and the same single cylinder keyed function. The difference is form: the F51A is a cylindrical bored lockset with a bell knob on both sides, while the Katana is a handleset with an exterior grip and separate interior trim, which changes the door prep and the look at the entry. Bravura also builds Grade 2 handlesets in the Savannah, Jacksonville, Austin and Montgomery series, the Montgomery pairing a 672 interior plate with a 939-Charlotte interior lever for openings where a lever is wanted on the inside.
9) Can an Emtek Select Brass Conical Stem Dark Walnut knob be used in place of a Schlage F51A bell knob on an exterior entry door?
No. The Emtek Select Brass Conical Stem Dark Walnut knob is a passage, hall and closet function, meaning it turns freely from both sides with no cylinder and no locking. The Schlage F51A bell knob is a keyed entry lock with a 5-pin C keyway single cylinder that locks by key from outside or by the interior turnbutton. The two share a knob format but not a function, so the Emtek knob suits an interior door where no security is required, and the F51A is the one that secures an entry.
10) Should I use a knob entry lock like the F51A or a handleset on a front door?
A cylindrical knob entry lock like the F51A is the workhorse choice: one bore, one lock, keyed entry, and it goes on any door regardless of hand. A handleset is a two-piece exterior grip plus deadbolt for a front entry where appearance matters and you want a separate deadbolt throw. If that's the job, the Bravura 913-Savannah or 915-Jacksonville Grade 2 handlesets, both with a 906-Macon interior knob, are the Grade 2 equivalents, and the Delaney Katana is another Grade 2 single cylinder handleset. Knob entry locks are the usual call for secondary exterior doors, garage-to-house, and unit doors across a portfolio.
11) What's the difference between a Grade 2 lock like the Schlage F51A and the Grade 3 options?
Grade is the ANSI/BHMA durability and strength tier, and the F51A sits at Grade 2 (plus Residential Grade AAA). Grade 3 is the lighter residential tier: the Callan Visconti and Briona handlesets and the Delaney Avino handleset are Grade 3, as are the Delaney Traditional and Contemporary deadbolts. For an apartment entry, a rental turnover door, or anything seeing daily traffic from multiple people, Grade 2 is the tier that holds up. Grade 3 is for lower-traffic residential openings.
12) Do I need a deadbolt as well as the F51A knob lock?
The F51A is a keyed entry knob with a 1/2 inch latch throw, which is a latch and not a deadbolt. On an exterior opening most people add a separate single cylinder deadbolt for the longer throw, and the Delaney Traditional or Contemporary Grade 3 single cylinder deadbolts (cylinder by thumbturn) are the pieces that pair with it. If you go that route, order the knob and the deadbolt keyed alike so one key runs both.
13) Is the F51A knob lock ADA compliant for a commercial or accessible unit?
A knob is a knob. The F51A uses a bell knob, which requires grasping and twisting, so it is not the choice where you need lever operation on an accessible opening. If the door needs a lever, look at an F Series lever in the same keyed entry function rather than this knob trim.
14) Can I order the F51A without a cylinder if I key my own?
Yes. The keying selection includes a None option for less cylinder, which is what a locksmith or an integrator running their own keyway wants. Otherwise pick keyed different or keyed alike and, if you're matching an existing system, enter the key code on the order.
15) Does the Schlage F51A come with everything needed to install, or do I have to buy the latch and strike separately?
Everything's in the box: the dual backset dead latch (round and drive-in options both included), the full lip radius strike, and two keys per lock. Install is a screwdriver job on an existing standard cylindrical bore. Nothing else to order unless you're adding a separate deadbolt.
16) Is a single cylinder deadbolt an alternative to the Schlage F51A entry knob, or does it go with it?
It goes with it rather than replaces it. The Delaney Traditional and Delaney Contemporary are Grade 3 single cylinder deadbolts with a cylinder by thumbturn function, which means they throw a bolt but carry no latch and no knob, so they cannot operate the door on their own. The Schlage F51A is a cylindrical bored lockset with a bell knob and a 16-086 dead latch, giving both the operating trim and the keyed entry function on one bore. Doors that want a second point of security take the knob lock in the lower bore and a deadbolt above it.
17) For a rental turn where a Grade 2 knob is more lock than the opening needs, what is the lighter duty keyed option?
The Callan Visconti and Callan Briona are Grade 3 single cylinder handlesets with interior trim, one ANSI/BHMA grade below the Grade 2 Schlage F51A bell knob entry lock, as is the Delaney Avino Grade 3 single cylinder handleset. All three keep the single cylinder keyed entry function. Where the difference matters is duty cycle and specification: the F51A carries a Grade 2 rating with zinc and steel construction for openings that see heavier traffic, and it is a knob on a bored prep rather than a handleset, so it will not fill a handleset door prep.
18) What should be specified instead of the Schlage F51A when the opening needs credential access rather than a key?
The Paxton PaxLock Pro Galaxy lever latch lock is the credential based option: it is a battery powered lever latch lock with a dual frequency reader at 13.56 MHz and 2.4 GHz, Bluetooth and AES128 encryption, built for a 1-3/4 inch door thickness and carrying ISED, UL and FCC marks. The Schlage F51A bell knob entry lock is a mechanical, non-electronic lock keyed on a 5-pin C keyway, and it fits doors from 1-3/8 to 1-3/4 inches, so it covers the thinner doors the PaxLock Pro does not. Choose by how the opening is credentialed: keys and a turnbutton on the F51A, cards and phones on the PaxLock Pro.
19) When a Bravura handleset is on the front door, can the Schlage F51A bell knob be used on the side and back entries?
It is a common pairing, with one caveat worth checking. The Bravura Savannah, Jacksonville and Austin handlesets are Grade 2 units that combine a 615 interior plate with a 906-Macon interior knob, so a Grade 2 keyed entry knob like the Schlage F51A matches them on rating for secondary entries. The F51A is non-handed and fits 1-3/8 to 1-3/4 inch doors on either a 2-3/8 or 2-3/4 inch backset, which covers most side and rear doors. The item to confirm is keying: the F51A uses a 5-pin C keyway, so a property wanting one key across all the doors should verify the handlesets can be keyed to the same system before ordering.
20) What finishes does the Schlage F51A bell knob come in?
Five, all with the bell knob design: 505 Lifetime Brass, 605 Bright Brass, 609 Antique Brass, 625 Bright Chrome and 626 Satin Chrome. If you're matching existing hardware in a building, 626 Satin Chrome and 605 Bright Brass are the two that most commonly sit alongside older Schlage residential trim. Lifetime Brass (505) is the one to pick if you want the brass look without the polish wearing off.
21) What is the F51A made of, and will it hold up on an apartment turnover door?
Zinc and steel construction, certified Grade 2 commercial and Residential Grade AAA. That's the tier property managers standardize on for unit entry and common-area doors where the same lock gets rekeyed and cycled repeatedly. Non-handed and dual backset means one part number covers every door in the building.
22) Is the Schlage F51A an electronic or smart lock?
No, it's a mechanical key-operated lock, no batteries or credentials. If you need electronic access control on the opening instead, the Paxton PaxLock Pro Galaxy lever latch lock is a battery powered reader lock with dual frequency 13.56 MHz and 2.4 GHz, Bluetooth and AES128, for 1-3/4 inch doors. That's a different install and a different management model, but it's the route if you want to stop cutting keys.
