Kwikset 721KNL-26D – Frequently Asked Questions

1) Do I have to order the Kwikset Kingston 721KNL passage lever left or right handed?
Handing is not a decision here. The Kingston 721KNL is reversible, so one part number covers a left or right hand door and the lever is set at install. That matters if you are buying for a floor of mixed openings, since you order quantity and finish only.
2) Can a Kwikset 721KNL passage lever go on a fire rated door?
Fire rated, yes. The 721KNL Kingston carries a fire rating, and a passage latch is the usual trim on a rated corridor or stairwell door where the closer and the latch do the work and locking is not wanted. The RCAL latch and RCS round corner strike ship in the box, so the whole latching assembly is the rated Kwikset hardware rather than a mixed set.
3) Will the RCS round corner strike on the Kwikset 721KNL fit my existing frame?
The 721KNL ships with a round corner strike, which suits a metal frame or a wood frame already routed with radius corners. If your frames are prepped square corner, the strike pocket will not match the radius and you will either need to file the mortise or swap in a square corner strike. Worth checking one frame before you order a building's worth.
4) Is the Kwikset 721KNL Kingston lever heavy duty enough for a commercial building?
The Kingston 721KNL is classified as residential hardware, sold for interior residential and light commercial doors. On a low-traffic office, a storage room, or an apartment interior it is fine. For a school corridor, a hospital, or any opening cycling hundreds of times a day, step up to a Grade 1 passage lever such as the Falcon K101 or the Corbin Russwin CL3110, both of which are Grade 1 and fire rated.
5) Is a dummy lever the same as the Kingston 721KNL passage lever?
No. The Kingston 721KNL is a passage lever with a latch and strike, so the lever retracts a latchbolt and holds the door closed. A dummy lever is fixed trim with no latch - the Accentra 455LN Augusta is a Grade 1 single dummy cylindrical lever, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim lever, and the BEST 7KC Series 1DT is a Grade 2 single dummy trim. Use a dummy on the inactive leaf of a pair or a ball catch door, and the 721KNL where the door needs to latch.
6) What is the closest equivalent to the Kwikset 721KNL Kingston passage lever from a commercial lock line?
For a non-keyed passage lever in a cylindrical format, the Falcon B101 is a Grade 2 medium duty cylindrical passage lever with a non-handed design, and the Hager 2510 is a Grade 2 passage cylindrical lever with the Withnell lever that covers doors 1-3/8 inch to 2 inch. Both do the same job as the Kingston 721KNL: latch the door, no locking, lever operation on hallways and closets. The Kingston 721KNL is reversible in hand and comes in Venetian Bronze, Satin Nickel, Satin Chrome and Polished Brass.
7) What passage lever should I use instead of the Kingston 721KNL on a heavy traffic commercial corridor?
Step up to a Grade 1 passage lever. The Falcon K101 is a Grade 1 heavy duty cylindrical passage lock with non-handed levers, fire rated, covering doors 1-3/8 inch to 2-1/4 inch. The Falcon T101 is a Grade 1 heavy duty cylindrical passage lever with pressure release technology. The Corbin Russwin CL3110 is a Grade 1 vandal resistant passage/closet lever, fire rated, for doors 1-3/4 inch to 2 inch. The Kingston 721KNL is built for light commercial and interior residential openings.
8) I need a lever that locks for a bedroom or restroom door - what takes the place of the Kingston 721KNL there?
The Kingston 721KNL is a passage lever with no locking mechanism, so it will not serve a bathroom or bedroom. For privacy, the Arrow MK02-TA is a privacy cylindrical lock, fire rated, for doors 1-3/4 inch to 2 inch, and the Baldwin Estate 5103 Privacy Lever with the 5048 rose is a privacy lever. If the opening needs a key, the Hager 2525 is a Grade 2 commercial cylindrical entry lock with a lever handle.
9) My door is 2 inches thick - which passage lever covers it if the Kingston 721KNL does not?
Passage levers in the set that state coverage to 2 inches include the Hager 2510, a Grade 2 passage lever rated 1-3/8 inch to 2 inch, and the Arrow GL01, a Grade 2 non-keyed passage lock rated 1-3/4 inch to 2 inch. For thicker stock, the Falcon K101 is a Grade 1 heavy duty passage lock rated 1-3/8 inch to 2-1/4 inch.
10) What is a good Grade 2 alternative to the Kwikset Kingston passage lever for a light commercial job?
If a spec calls for a graded lock and the Kingston does not meet it, the closest same-function options are the Arrow GL01 Sierra lever, Grade 2 passage, rated for 1-3/4 to 2 inch doors, and the Hager 2510 Withnell, Grade 2 passage, rated for 1-3/8 to 2 inch doors. The Falcon B101 is another Grade 2 passage lever with a non-handed design. All three do the same job as the Kingston, just written to a commercial grade.
11) Do I need to buy the latch and strike separately with the Kwikset 721KNL?
No extras needed for the latching. The RCAL latch and RCS round corner strike come with the 721KNL Kingston, along with the mounting screws for a standard cylindrical door prep. What is not included is anything for the frame beyond the strike, so if the door needs a closer, silencers, or a wall stop those are separate lines on the order.
12) Can I use the Kwikset Kingston lever on a bathroom or bedroom door?
Only if you do not want it to lock. The Kingston 721KNL has no locking mechanism at all, so a bathroom or bedroom needs a privacy set with a pushbutton and emergency release. For that function, look at the Hager 2540 with the Withnell lever or the Arrow MK02-TA privacy set. Keep the passage version for the hall and closet doors on the same job.
13) Is the Kwikset 721KNL a cylindrical lock that drops into a standard 2-1/8 inch bore?
It is a cylindrical lockset, the common bored type, and it installs in standard cylindrical door prep. That is the 2-1/8 inch cross bore with a 1 inch edge bore that nearly every interior door in North America already has, which is why swapping an old knob or lever for the Kingston is usually a screwdriver job with no new boring.
14) What Grade 2 passage lever alternatives are there to the Kwikset Kingston 721KNL?
Several. The Accentra 5301LN Augusta is a Grade 2 passage/closet cylindrical lever in the 5300 Series and the Accentra 4601LN is a Grade 2 passage lever with Augusta trim in the 4600 Series. The Arrow GL01 is a Grade 2 passage cylindrical lock with the Sierra lever, non-keyed, for doors 1-3/4 inch to 2 inch. The Design Hardware J75 is a Grade 2 passage lever lockset with a flat lever for 1-3/4 inch doors. All are non-keyed passage like the Kingston 721KNL.
15) What is the difference between the Kingston 721KNL and a keypad lever like the Lockey 2835?
The Kingston 721KNL is non-keyed passage hardware: the lever always turns and the door never secures. The Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for doors 1 3/16 inch to 2 inch, and the Lockey 2835DC adds a double combination on the same door thickness range. Those give code-controlled access on the same style of opening; the Kingston 721KNL simply latches.
16) If I want a passage lever with a decorative rose instead of the Kingston 721KNL, what is comparable?
The Baldwin Estate 5103 Passage Lever with the 5048 rose is a passage function lever with an estate style trim, and the same 5103 lever is offered as a left hand half dummy and a right hand half dummy if a pair of doors needs matching fixed trim. The Bravura Miramar with round trim is a Grade 2 passage leverset in US4 Satin Brass, and the Bravura Tampa is a Grade 2 passage leverset with square trim. The Kingston 721KNL uses a traditional style lever and is reversible in hand.
17) Can I standardize a floor on the Kingston 721KNL and add keyed openings from the same lever family?
The Kingston 721KNL is passage only and non-keyed, so keyed openings on the same floor need a separate lockset. For a storeroom door the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for doors 1-3/8 inch to 1-3/4 inch, and the Hager 2580 is a Grade 2 storeroom lever with the Withnell lever for 1-3/8 inch to 2 inch. For a classroom the Dexter C1000 is a Grade 1 keyed classroom cylindrical lever with clutching for 1-3/8 inch to 1-3/4 inch doors.
18) Will the Kingston lever match the traditional trim on the rest of my building's doors?
The Kingston is a traditional style lever on a round rose, so it sits alongside older trim rather than clashing with it. Where you want a squarer, more contemporary look on the same job, the Bravura Tampa passage leverset uses square trim, and the Bravura Orlando and Atlanta both use round trim. All are passage function, so they interchange on the same openings.
19) Is the Callan Asheville passage leverset a drop-in match for the Kingston 721KNL?
The Callan Asheville is a Grade 3 passage leverset in Satin Nickel, so it covers the same function as the Kingston 721KNL - a hall, closet or interior door that latches without locking - at a lighter grade. The Kingston 721KNL is offered in Satin Nickel as well as Venetian Bronze, Satin Chrome and Polished Brass, so a floor mixing the two can still be finish matched.
