Accentra YAL-MO-4728LN-626 – Frequently Asked Questions

1) What does the communicating function on the Accentra 4728LN lever lock actually do?
The 4728LN is a non-keyed communicating lock: levers operate the latch from both sides at all times, so it is a passage-style lock with no locking and no cylinder. It's used where two rooms connect and you want free travel between them with lever hardware on both faces. If you need to secure the opening, this is the wrong function - look at a storeroom, classroom, or entrance function in the same 4700 family instead.
2) Will the Accentra 4728LN fit a 1-3/4 inch commercial door?
Yes. The 4700LN trim is adjustable from 1-3/8 to 1-3/4 inches, which covers the 1-3/4 inch standard commercial door and the older 1-3/8 inch interior door. If your doors run thicker than 1-3/4 inches, up to 2 inches, that's the 4700 (non-LN) version's range, and it comes only in satin stainless steel 630.
3) Will the 4728LN latch into the strike that's already in my frame?
The latchbolt throws 1/2 inch in stainless steel and ships with a standard ANSI strike, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. If your existing frame is prepped for that ANSI strike, the lock drops in and you can reuse the cut. Aluminum or wood frames cut for a smaller T-strike need the optional T-strike, which is available to order for the 4700LN. Front is 2-1/4 x 1-1/8 inches beveled as standard, with flat fronts available to order.
4) Can the Accentra 4728LN go on a fire-rated door?
Yes. The 4700LN series carries UL-cUL fire ratings up to 3 hours and is ANSI/BHMA A156.2 Series 4000 Grade 1. It's also 4700LN Windstorm certified, though you should follow your local code on windstorm openings.
5) What backset does the Accentra 4728LN use, and will it work on a door bored at 2-3/8 inches?
The 4728LN is a 2-3/4 inch backset lock, which is the usual commercial bore. It will not line up on a door already cross-bored at 2-3/8 inches. If your existing prep is 2-3/8, one option we carry is the Cal-Royal AG00 lever, listed with a 2-3/8 inch backset, though that's an entrance function rather than communicating.
6) I need a Grade 1 passage lever but my doors are 1-3/4 to 2 inches thick. What else do you have?
The 4700LN trim tops out at 1-3/4 inches, so it won't cover a 2 inch door. Two Grade 1 alternatives we carry that do: the Corbin Russwin CL3110 passage/closet lever, rated for 1-3/4 to 2 inch doors and fire rated, and the Falcon K101 Grade 1 passage lock, listed for 1-3/8 to 2-1/4 inches and also fire rated. Either covers thick doors with the same free-passage operation.
7) What is a Grade 1 non-keyed cylindrical lever equivalent to the Accentra 4728LN for a door that is 1-3/4 inch to 2 inch thick?
The Accentra 4728LN is adjustable from 1-3/8 inch to 1-3/4 inch in the 4700LN configuration, so a thicker door needs a different lock. The Corbin Russwin CL3110 is a Grade 1 non-keyed passage/closet cylindrical lever lock with a 1-3/4 inch to 2 inch door thickness range and a fire rating, which covers that thicker leaf. The Falcon K101 is also Grade 1 passage and fire rated with a wider 1-3/8 inch to 2-1/4 inch range if you want one part number that spans both thin and thick doors.
8) The Accentra 4728LN is non-keyed. What Grade 1 lever should I order for the same opening if it needs a key?
The 4728LN is a non-keyed communicating function, so it offers no key control. For keyed Grade 1 cylindrical levers on comparable commercial doors, the Dexter C1000 classroom lever is keyed with a clutching mechanism over a 1-3/8 inch to 1-3/4 inch door range, the C1000 classroom security version adds the second keyed cylinder, and the Corbin Russwin CL33903 is a Grade 1 fail safe electrified lever at 12VAC/DC for 1-3/4 inch to 2 inch doors when access control is involved.
9) If a bathroom or bedroom door needs to lock from the inside, can I use the Accentra 4728LN?
No. The 4728LN is a non-keyed communicating passage function with no locking on either side. For a privacy function on those doors, the Arrow MK02-TA is a privacy cylindrical lock with a Tudor knob and a fire rating for 1-3/4 inch to 2 inch doors, and the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors if you want to keep lever trim throughout.
10) What should I use instead of the Accentra 4728LN on a behavioral health or utility door?
The 4728LN is a non-keyed communicating passage lock, which gives no key control on either side. Asylum function is the usual call on behavioral health and utility openings: the Dexter C1000 asylum (F87) is a Grade 1 cylindrical lock covering 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a heavy-duty asylum lock with a ball knob and a conventional Schlage C keyway cylinder.
11) Do I need to specify handing when I order the 4728LN Monroe lever?
No. The 4700LN is non-handed and reversible, so one part number covers left and right hand openings. That's useful for a property manager stocking spares - a single lock on the shelf fits any door in the building.
12) Which finishes does the Accentra 4728LN Monroe lever come in?
Eight choices on the LN trim: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 625 bright chrome, 626 satin chrome, plus BSP black suede and WSP white suede powder coat. For a building already standardized on satin chrome, 626 is the match most commercial openings use. The heavier 4700 (1-3/4 to 2 inch) version is satin stainless 630 only, so a mixed-thickness building won't finish-match across both.
13) What's the difference between the Accentra 4728LN and a Grade 2 passage lever like the Falcon B101?
Both put a non-handed lever on a free-swinging door, but they sit at different duty levels. The 4728LN is ANSI/BHMA Grade 1 with a heavy-gauge steel, die-cast, zinc-plated and chromated mechanism, and is UL-cUL fire rated to 3 hours. The Falcon B101 is a Grade 2, medium duty passage lever. For high-traffic school, healthcare, or multi-family corridors go Grade 1; for light interior traffic Grade 2 is the cheaper spec.
14) Does the Accentra 4728LN come with a cylinder or keys?
No cylinder and no keys with the 4728LN - it's a non-keyed communicating lock, so there's nothing to key. Cylinder options in the 4700 family (brass 6-pin keyed-random with two keys) apply to the keyed functions, not this one. Note that 7-pin cylinders are not offered anywhere in the series, so if your facility is keyed on a 7-pin system this family won't join it.
15) Is a dummy lever the same thing as this communicating lock?
No, and this catches people out. The 4728LN has a working latchbolt with a 1/2 inch throw, so the door actually latches shut and the levers retract it. A dummy trim, like the BEST 9K Series 1DT Grade 1 single dummy or the 7KC Series 1DT Grade 2, is a fixed pull with no latch at all - it's for an inactive leaf or a door held by a magnetic catch. Order the dummy only if there is nothing to latch.
16) Will the 4728LN keep the door from being pushed open or the latch shimmed?
There's no guardbolt on the 4728LN. The guardbolt that deadlocks the latchbolt when the door closes is standard on the locking functions in the 4700 family, and the 4728LN is a non-keyed communicating lock with no locking. If you need a deadlocking latch on the opening, specify a keyed function such as storeroom or entrance from the series, or look at a Grade 2 alternative like the Cal-Royal AG05 storeroom lever, which lists a deadlocking latchbolt.
17) How does the Accentra 4728LN compare with the Falcon T101 for a high-traffic passage opening?
Both are Grade 1 cylindrical lever locks intended for heavy commercial traffic. The 4728LN runs a communicating passage function with a 2-3/4 inch backset, non-handed reversibility, and UL fire rating up to 3 hours. The Falcon T101 is a Grade 1 heavy-duty cylindrical passage lever built with pressure release technology in the T Series. Choose on trim design and the latch and strike prep already in the door.
18) Is the Design Hardware X75 a drop-in alternative to the Accentra 4728LN?
Both are Grade 1 non-keyed passage lever locksets. The X75 is specified for 1-3/4 inch doors, while the 4728LN in the 4700LN configuration adjusts from 1-3/8 inch to 1-3/4 inch, so the Accentra covers thinner leaves as well. Confirm backset and strike prep, since the 4728LN ships with a 2-3/4 inch backset and an ANSI 4-7/8 inch strike.
19) Can a residential passage leverset replace the Accentra 4728LN in an apartment building corridor?
The 4728LN is a Grade 1 commercial cylindrical lever with UL fire rating up to 3 hours, which is what corridor and fire-rated openings usually call for. Residential-grade options such as the Kwikset 200BRNL Breton passage lever and the Callan Asheville passage leverset are Grade 3, and the Bravura Atlanta and Orlando passage leversets are Grade 2. Those suit unit interior doors rather than rated corridor openings.
20) Which keyless entry lever would I use in place of the Accentra 4728LN if the door needs code access?
The 4728LN has no keypad and no keyed cylinder in this function. For code access on a lever, the Lockey 2835 mechanical pushbutton keyless lever lock is ADA compliant and fits 1-3/16 inch to 2 inch doors, the 2835DC adds a double combination, and the Lockey 1150 heavy-duty keypad lever set covers 1-1/8 inch to 2 inch doors. The Delaney LP250 is an electronic keypad leverlock at Grade 2.
21) What is the lever alternative to the Accentra 4728LN for a storeroom door?
The 4728LN is non-keyed and will not secure a storeroom. For that function with lever trim, the Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt over the same 1-3/8 inch to 1-3/4 inch range the 4728LN covers.
