Accentra MO-455LN-D-626 – Frequently Asked Questions

1) Can I use the 455LN-D dummy lever on a fire rated door?
The 5400LN Series carries a UL/cUL fire rating up to 3 hours and is certified to ANSI/BHMA A156.2 Series 4000 Grade 1. It is also windstorm certified, subject to your local code. Since a dummy has no latch, it does not provide the positive latching a fire door assembly needs on its own, so it belongs on the inactive leaf or a location where latching is handled by other hardware.
2) I need a lever that actually opens the door, not a dummy. What is the equivalent?
Stay Grade 1 and move to a passage function. The Falcon K101 is a Grade 1 heavy duty non-handed passage cylindrical lock rated for 1-3/8 to 2-1/4 inch doors and fire rated, which covers the same thickness range as the Accentra Monroe dummy. The Corbin Russwin CL3110 is another Grade 1 passage/closet option, fire rated, for 1-3/4 to 2 inch doors. For a lighter duty closet door, the Arrow GL01 is Grade 2 passage.
3) What is the closest Grade 1 commercial equivalent to the Accentra 455LN-D double dummy lever?
The BEST 9K Series 1DT is the nearest heavy duty Grade 1 dummy cylindrical lever trim. The difference is scope: the Accentra 455LN-D Monroe is a double dummy, so it supplies fixed lever trim on both faces of the door, while the 9K 1DT is a single dummy trim for one face only. On a pair of doors or a double-acting opening where both sides need a lever, you need the double dummy or two single dummy trims.
4) I need the lever to actually retract a latch, not just sit fixed. What should I order instead of the 455LN-D?
A dummy has no latch and no moving mechanism, so it will not operate a door. For a latching non-keyed opening in the same Grade 1 heavy duty class, look at the Falcon K101 passage, which is fire rated and covers 1-3/8 inch to 2-1/4 inch doors, the Falcon T101 heavy duty passage lever, the Corbin Russwin CL3110 passage/closet vandal resistant lever for 1-3/4 inch to 2 inch doors, or the Dexter C1000 passage. Keep the 455LN-D for the inactive leaf or pull-only side.
5) The opening needs key control. Is the 455LN-D the wrong choice?
Yes, for a keyed opening. The Accentra 455LN-D Monroe is non-keyed dummy trim with no cylinder function. For keyed cylindrical levers, the Dexter C1000 classroom and classroom security are Grade 1 keyed clutching levers, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. Pair a keyed lever on the active leaf with the 455LN-D on the inactive leaf.
6) My door is 2-1/4 inches thick. Which of these lever options actually covers it?
The Accentra 455LN-D Monroe adjusts from 1-3/4 inch to 2-1/4 inch. Among the comparable levers, the Falcon K101 passage covers 1-3/8 inch to 2-1/4 inch. Several others stop short: the Corbin Russwin CL3110 and CL33903 are 1-3/4 inch to 2 inch, the Hager 2510 passage is 1-3/8 inch to 2 inch, and the Design Hardware X75 passage is listed for 1-3/4 inch. Confirm thickness before substituting on a thick or lead-lined door.
7) What finishes does the Accentra Monroe 455LN-D dummy lever come in?
Nine finishes to order from: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, BSP black suede powder coat and WSP white suede powder coat. PVD is standard on 605 and 606, which matters if the doors are exterior or in a coastal building where plated brass tarnishes. For matching a building already on 626 satin chrome, that is the common commercial finish.
8) Do I need to worry about handing when ordering the Monroe 455LN-D lever?
No. The Monroe lever trim in the 5400LN line is non-handed and reversible, so one part number covers left and right hand doors. That is the opposite of something like the Baldwin Estate 5103 half dummy, which is ordered specifically as a left hand or right hand part.
9) Will a 455LN-D double dummy match the other Monroe levers already on my building?
Yes, that is the point of buying it. The Monroe lever and rose used on the 455LN-D is the same trim used across the 5400LN Series Grade 1 cylindrical locks, so closet and inactive-leaf doors read identically to the keyed and passage openings around them. Order the same finish code and the doors match.
10) Does the 455LN-D dummy need the standard 2-3/4 inch cylindrical door prep?
It mounts to the standard 5400LN cylindrical prep, which is 2-3/4 inch backset on the latching functions in the series. Because a dummy has no chassis or latch running into the edge of the door, you are only dealing with the 2-1/8 inch cross bore for the roses, and there is no edge bore or strike to cut. That makes it a straightforward swap onto a door that already had a cylindrical lockset in it.
11) Will a Baldwin 5103 half dummy work in place of the Accentra 455LN-D?
Only for one face. The Baldwin Estate 5103 half dummy with 5048 rose is handed and sold as a left hand or a right hand unit, so a two-sided opening takes two pieces. The Accentra 455LN-D Monroe is non-handed and covers both faces as a double dummy set. The Baldwin is a residential-style decorative lever, while the 455LN-D is a commercial Grade 1 cylindrical trim.
12) I need lever trim for an exit device, not a dummy. What should I look at?
Dummy trim like the Accentra 455LN-D Monroe mounts to the door face and does not drive an exit device. For pushpad exit device trim, the Corbin Russwin 585F715 is a Grade 1 lock lever for the ED8000 pushpad exit device, listed for 1-3/4 inch to 2 inch doors, and the Imperial USA ED-EL500HD is heavy duty escutcheon lever trim with an entry function.
13) Is a passage lever the same thing as a dummy lever?
No, and it is the most common mix-up on an order. A passage lever such as the Falcon B101 Grade 2, the Arrow GL01 Grade 2 Sierra, or the Bravura Atlanta Grade 2 has a working latch and the lever retracts it. The Accentra 455LN-D Monroe is a double dummy: the levers are fixed and there is no latch or strike involved. Use a dummy on an inactive leaf, a ball-catch door, or a pull-only closet.
14) What matches the 455LN-D on a bathroom or bedroom door that needs privacy?
A dummy cannot lock, so the Accentra 455LN-D Monroe is not a privacy option. For privacy function, the Arrow MK02-TA is a fire rated privacy cylindrical lock with a Tudor knob, the Hager 2540 covers 1-3/8 inch to 2 inch doors, the Baldwin Estate 5103 privacy lever uses the 5048 rose, and the Kwikset 300BRNL Breton privacy leverset is Grade 3 for 1-3/8 inch to 1-3/4 inch doors.
15) Can a keypad lever be used on the same opening instead of dummy trim?
Only where the door needs code-based entry. The Accentra 455LN-D Monroe is fixed dummy trim with no operating mechanism. Keyless lever options include the Lockey 2835 and 2835DC mechanical pushbutton lever locks for 1 3/16 inch to 2 inch doors, the Lockey 1150 heavy duty keypad lever set for 1-1/8 inch to 2 inch doors, and the Delaney LP250 Grade 2 electronic keypad leverlock. These are latching, credential-based locks and serve a different purpose than a dummy.
