Weslock 066215252SL2D – Frequently Asked Questions

1) Will the Weslock 6621 Addy handleset fit a 2 inch thick entry door?
Yes. The 6621 Addy adjusts to door thicknesses from 1-3/8 inches all the way to 2-1/4 inches, so a 2 inch slab is inside the range with no shim kit or spacer to order. That upper end matters if you have a heavy custom or solid wood front door: most residential handlesets stop at 1-3/4 inches. Among the comparable handlesets, the Schlage Residential F60 Addison with Accent lever and the Pamex FS7P31 Lexington are both rated 1-3/8 inches to 1-3/4 inches, and the Deltana 810871 Montego covers 1-3/8 inches to 2 inches. If the door is thicker than standard, the Weslock is the wider-range option of that group.
2) What backset does the Weslock 6621 Addy handleset need, and will it match my existing door prep?
The 6621 Addy ships with an adjustable backset that sets to either 2-3/8 inches or 2-3/4 inches, the two standard residential backsets, so you do not have to measure and order a specific version. Radius faceplates and both round and square full-lip strikes are in the box, which covers a jamb already mortised for either strike shape. Measure from the door edge to the center of the bore hole to confirm which of the two you are on before you install.
3) Can the Weslock 6621 handleset go into the holes my old handleset left, or do I have to re-bore the door?
The 6621 Addy needs a 2-1/8 inch top bore (a 1-5/8 inch top bore also works), a 2-1/8 inch bottom cross bore for the deadbolt, and a 1 inch edge bore. That is the standard two-hole handleset prep, so a door already drilled for a common entry handleset with a deadbolt above usually takes it without new holes. The two things to check first are the spacing between your existing bores and the backset, which sets to 2-3/8 or 2-3/4 inches. If your old set used a single bore and no separate deadbolt hole, the door will need drilling.
4) Can I get the Weslock 6621 Addy keyed alike to the other locks on my property?
Keyed alike is an option when you order, and you can supply a key code, so a set of 6621 Addy handlesets can be ordered on one key for a rental unit or a house with more than one entry. The limit is the keyway: the deadbolt uses a Weslock 5-pin cylinder on the Weslock keyway, so it keys alike only with other Weslock keyway cylinders. It will not key alike with Schlage SC1 or Kwikset KW1 hardware already on the building. Ordered keyed different, each unit gets its own key.
5) Does the Weslock 6621 Addy handleset include the inside lever, or is it exterior trim only?
Complete set. The 6621 Addy comes as the exterior escutcheon handle with the Atlas lever for the inside, plus the single cylinder deadbolt, faceplates and strikes. Nothing separate to buy to finish the door. Worth knowing if you are cross-shopping: some handlesets are sold as the outside half only, such as the Kwikset 687AMD Amador single cylinder handleset, which is listed as exterior only and needs interior trim ordered alongside it.
6) What is the closest equivalent to the Weslock 6621 Addy handleset with Atlas lever?
The Schlage Residential F60 Addison single cylinder keyed entry handleset with Accent lever is the nearest match in both function and form: both are single cylinder keyed handlesets with a lever interior trim, and both sit at the same grade level, with the F60 Addison rated Grade 2 and the Weslock 6621 exceeding ANSI Grade 2 lock standards. Two things separate them. Door thickness is the first - the F60 Addison fits 1-3/8 to 1-3/4 inch doors, while the 6621 Addy adjusts from 1-3/8 to 2-1/4 inch. Keying is the second - the 6621 runs a 5-pin cylinder in the Weslock keyway, so it will not key into a Schlage system without a cylinder change.
7) Which entry handleset works on a door thicker than 1-3/4 inches?
The Weslock 6621 Addy adjusts to door thicknesses from 1-3/8 to 2-1/4 inch, which covers a 2 inch or 2-1/4 inch slab without a thick-door kit. Most of the comparable mechanical handlesets stop earlier: the Schlage F60 Addison and the Pamex FS7P31 Lexington are rated 1-3/8 to 1-3/4 inch, the Kwikset 687AMD Amador is 1-3/4 inch, and the Deltana 810871 Montego runs 1-3/8 to 2 inch. On the electronic side, the Yale Assure Lock BYRD226NRRX with Ridgefield handleset covers 1-3/4 to 2-1/4 inch. Measure the slab at the bore before ordering, since a 2 inch door narrows the field considerably.
8) Is the Emtek 3002 Memphis mortise entrance handleset a substitute for the Weslock 6621 Addy?
No, and the names make it easy to confuse. The Emtek 3002 Memphis is a dummy function handleset - fixed trim with no latch and no cylinder, meant for an inactive leaf or a door held by a separate catch. The same is true of the Emtek 3004 Hamilton, 3005 Melrose, and 3006 Manhattan, all dummy function. The Weslock 6621 Addy is a keyed single cylinder handleset with a deadbolt lock function, so it secures the opening. If a dummy trim is installed where a locking entry set was specified, the door will not lock at all.
9) Does the Weslock 6621 Addy come with interior trim, or do I order that separately?
The 6621 Addy is a complete set - the exterior escutcheon handle, the Atlas lever for the inside, and the single cylinder deadbolt come together. That is worth checking against the alternatives, because several are sold as exterior trim only: the Kwikset 687AMD Amador in both the SmartKey and SC1 keyway versions, and the Kwikset 687BW Belleview, are exterior only and need interior trim sourced separately. The Kwikset 815SCEHFL San Clemente, by contrast, includes a Halifax lever interior trim.
10) What is the difference between the Weslock 6621 Addy handleset and the Baldwin Estates 6542 Tremont entry trim?
They mount to two different door preps. The Baldwin Estates 6542 Tremont, in the single cylinder BAL-6542ENTR and double cylinder BAL-6542DBLC versions, is entry mortise trim for a 1-3/4 inch door - it dresses a mortise lock body seated in a milled pocket in the door edge, and the lock body is a separate purchase. The Weslock 6621 Addy is a bored set: it goes into a 2-1/8 inch cross bore with a 1 inch edge bore, on a 2-3/8 or 2-3/4 inch backset. A door bored for the Weslock cannot take the Baldwin mortise trim without a new door or a mortise conversion.
11) Is a single cylinder deadbolt the right choice for a front door with glass next to it?
The 6621 Addy is single cylinder, meaning key outside and a turn piece inside. That is the usual choice and it exits freely in a hurry, but if there is glass in the door or a sidelight within reach of the inside turn, an intruder can break the glass and turn it. In that situation buyers go to a double cylinder, keyed both sides, which needs a key to get out. The Baldwin Estates 6542 Tremont is offered in a double cylinder entry version if that is the direction you need. Check your local code first, since some jurisdictions restrict double cylinder deadbolts on a required exit door.
12) Is the Weslock 6621 Addy handleset OK on the door between an attached garage and the house?
It carries a 20-minute UL fire rating, which is the rating a house-to-garage door assembly is typically built to, so the 6621 Addy is usable on that opening. Two practical points on that door: it needs a self-closing hinge or closer to stay latched, and the handleset adjusts to doors from 1-3/8 to 2-1/4 inches thick, which covers the 1-3/8 inch solid core slabs common on that opening.
13) Is the Weslock 6621 Addy handleset heavy duty enough for an apartment or office entry?
The 6621 Addy is a residential handleset. It exceeds ANSI Grade 2 lock standards, which puts it above a builder-basic Grade 3 set and makes it reasonable for a single-family front door, a townhome, or a rental unit entry. For a commercial opening with public traffic, a door closer, and panic or accessibility requirements, specify a Grade 1 cylindrical or mortise lock instead of a residential handleset. Among the comparable handlesets, the Kwikset 687AMD Amador and 687BW Belleview are Grade 3, and the Schlage F60 Addison and Master Lock HDLB Series handleset are Grade 2.
14) How much room does the Weslock Addy handleset take up on the door face, and will it clear my sidelight trim?
The escutcheon measures 11 inches by 2.8 inches with a 2.5 inch projection. Lay that 11 inch dimension out vertically on the stile and the 2.8 inch across it, then check the clearance to your sidelight casing or brick mould before you drill. The 2.5 inch projection is what a storm door or screen door needs to swing past, so measure that gap too if there is a second door in front.
15) I want a keypad or app-controlled front door instead of a keyed handleset. What is the equivalent?
The Weslock 6621 Addy is a mechanical, keyed set: 5-pin Weslock cylinder, no electronics and no batteries. If you want keypad or phone entry in a handleset format, the Yale Real Living Assure Lock handlesets with the Ridgefield grip cover it, in a standalone touchscreen version and Wi-Fi and Bluetooth versions, rated for 1-3/4 to 2-1/4 inch doors. Kwikset's San Clemente handleset with the Halifax lever and a SmartCode keypad deadbolt is another, rated for 1-3/4 inch doors. Stay mechanical if the door is unheated, unpowered, or you simply do not want a battery to manage.
16) I need a handleset that keys into an existing SC1 system - is the Weslock 6621 the right choice?
The 6621 Addy is keyed on a 5-pin cylinder in the Weslock keyway, so it operates on a Weslock key, not an SC1 key. If the building is already standardized on SC1, the Kwikset 687AMD SMC Amador single cylinder handleset is built around an SC1 keyway with SmartKey - note that it is exterior trim only, so the inside lever is a separate line. The Kwikset 687AMD SMT and 687BW Belleview use SmartKey without the SC1 designation. Where the property is being rekeyed anyway, the Weslock keyway on the 6621 is a clean starting point for a new key system.
17) The 6621 Addy is single cylinder - what do I use where a key is required on both sides?
The 6621 Addy Atlas is a single cylinder keyed function, keyed from the outside only. For an opening where the inside also needs a key - a door with glass within reach of the deadbolt, where the local code official permits double cylinder - the Baldwin Estates 6542 Tremont double cylinder entry mortise trim, BAL-6542DBLC, is keyed both sides. It is mortise trim for a 1-3/4 inch door, so it is a different door prep, not a drop-in swap. Confirm the double cylinder allowance with the authority having jurisdiction before specifying, since egress rules vary by occupancy.
18) Is there a keypad or smart lock version of a handleset with a deadbolt like the Weslock 6621?
The 6621 Addy is mechanical, keyed on a 5-pin Weslock cylinder. For a keypad opening, the Kwikset 815SCEHFL-CP913CNT San Clemente handleset pairs a contemporary SmartCode keypad electronic deadbolt with a Halifax lever interior and fits a 1-3/4 inch door. Yale offers the Ridgefield handleset with three deadbolt options: the BYRD226NRRX standalone touchscreen, the BYRD226CBARX with Wi-Fi and Bluetooth, and the BYRD256 CBARX key free touchscreen connected by August, all rated 1-3/4 to 2-1/4 inch door thickness. The mechanical 6621 stays the choice where there is no interest in batteries or an app.
19) What finish does the Weslock 6621 Addy handleset come in?
Matte black, and that is the only finish it is built in, so the whole set (escutcheon, grip, deadbolt ring and Atlas lever) arrives matching out of the box. If you are standardizing a building on matte black, the body is zinc alloy with concealed installation screws, so there are no visible fasteners breaking up the face. Buyers wanting a solid brass substrate in the same handleset format look at the Deltana Hanover, St. Ann and Kingston entry handlesets instead.
20) I need the same handleset look on a door that does not need to lock. What do I use?
The 6621 Addy is a keyed entry set with a working deadbolt, so it is the wrong part for an inactive leaf or an interior door you only want to pull shut. For a non-keyed handleset in entry style, the Schlage Residential JE285 Barcelona with the Seville lever is a non-keyed entry function. For an inactive door or the fixed half of a pair, Emtek's Memphis, Hamilton, Melrose and Manhattan brass mortise entrance handlesets are made as dummy trim, meaning they mount to the face with no latch behind them.
21) Which handlesets use a knob on the inside instead of a lever?
The Weslock 6621 Addy uses the Atlas lever for the interior trim. Where a knob is wanted for the interior instead, Baldwin builds the Wesley handleset two ways: the BAL-180WYHXATK with the Alcott knob and the BAL-180WYHXCYK with the Carnaby knob, both entrance function. The choice is not only cosmetic - a lever is the operable hardware required on accessible openings, so on a unit door subject to accessibility requirements the lever interior on the 6621 is the safer specification.
22) What should I use on a second entry door that does not need to be keyed?
The 6621 Addy is a keyed set with a single cylinder deadbolt, which is more hardware than a secondary door needs if it is only being pulled shut. The Schlage Residential JE285 Barcelona handleset with Seville lever is a non-keyed entry function set, Grade 2, for 1-3/8 to 1-3/4 inch doors, and it keeps the handleset look on a door that latches without a key. Ordering matched keyed and non-keyed sets is common on a front and side door pair where only one carries the security.
23) Is there another single cylinder handleset in satin nickel rather than matte black?
The Weslock 6621 Addy with Atlas lever is finished in matte black. For a satin nickel opening, the Pamex FS7P31 Lexington single cylinder handleset comes in a satin nickel finish, entry function, sized for 1-3/8 to 1-3/4 inch doors. Where a fleet of doors is being standardized on one finish, the door thickness is the constraint to check first: the Pamex covers up to 1-3/4 inch, while the 6621 Addy adjusts from 1-3/8 to 2-1/4 inch.
24) The spec calls for an interconnected lock on the unit doors - can I use the Weslock 6621 Addy?
The 6621 Addy is a bored handleset with a separate single cylinder deadbolt, so the latch and the deadbolt are operated independently. Where the drawing or the code official calls for an interconnected lock, the Schlage Residential JI18/19 interconnected passage lock with keyed deadbolt and Torino lever in satin stainless steel is built for that condition - Grade 2, JI Series, for 1-3/8 to 1-3/4 inch doors. Confirm which one the plan requires before ordering, since the two are not interchangeable on a multi-family unit entry door.
