Accentra AU-5403LN-626 – Frequently Asked Questions

1) What does the patio function on the Accentra 5403LN Augusta lever lock actually do?
The 5403LN is a non-keyed patio/privacy lock. It locks by a turn or button on the inside only, with no key cylinder on the outside, so once it is locked from inside nobody gets back in from the corridor or patio side. That makes it right for patio doors, restrooms and bedrooms, and wrong for any opening where staff need key override. The ANSI/BHMA function code is F77.
2) What backset does the 5403LN Augusta lever lock use, and can it work in a door bored for a different backset?
Standard is 2-3/4 inches, which is the usual commercial bore. If the door is prepped deeper, extension links for 3-3/4 inch or 5 inch backsets are available to order. There is no 2-3/8 inch option, so a residential-prepped door bored at 2-3/8 will not take it without redrilling.
3) Will the 5403LN latch into the strike already in my frame?
Latchbolt throw is 1/2 inch stainless steel as standard, with a 3/4 inch throw available to order. The standard strike is a 1-1/4 inch curved lip sized for a 1-3/4 inch door, and other lip lengths can be ordered when the frame is set back or the door is thicker. All strikes are reversible. If your existing strike is a 1/2 inch throw ANSI prep, the standard latch drops straight in.
4) Can the 5403LN patio lock go on a fire rated door?
Yes. The 5400 Series carries 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 local code. Note the patio function has no outside key access, so confirm the opening does not require key override under your facility's fire plan.
5) What is a Grade 1 alternative to the Accentra 5403LN Augusta if the opening needs a keyed classroom function instead of patio?
The Accentra 5403LN Augusta is a non-keyed lever lock with a patio/privacy function, so it cannot be keyed for classroom control. The Dexter C1000 Series classroom cylindrical lever lock is Grade 1, keyed, with a clutching lever and a 1-3/8 inch to 1-3/4 inch door thickness range. For classroom security, the Dexter C1000 Series Classroom Security lever is also Grade 1 and keyed with the same 1-3/8 inch to 1-3/4 inch door range.
6) What looks like the Accentra 5403LN Augusta but will not latch or lock the door?
Dummy trim. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy cylindrical lever trim and the BEST 7KC Series 1DT is a Grade 2 medium duty single dummy lever - both are pull trim with no latch and no locking device. The Accentra 5403LN Augusta is a working cylindrical lockset with a patio/privacy function and a guardbolt that deadlocks the latchbolt when the door is closed. Use dummy trim only on the inactive leaf or a fixed panel.
7) What should be used instead of the Accentra 5403LN Augusta on an opening that needs keyed entry from the outside?
The Accentra 5403LN Augusta is non-keyed, locking only from the inside. For a keyed exterior opening, the Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors. If Grade 1 storeroom control is wanted instead, note the 5403LN backset is 2-3/4 inch while the Cal-Royal AG00 is 2-3/8 inch, so door prep differs.
8) Will the Accentra 5403LN Augusta fit a thicker door than most Grade 2 levers?
Yes. The Accentra 5403LN Augusta adjusts from 1-3/4 inch to 2-1/4 inch door thickness. Among comparable levers, the Hager 2510 passage and Hager 2580 storeroom cover 1-3/8 inch to 2 inch, the Arrow GL01 passage covers 1-3/4 inch to 2 inch, and the Design Hardware J75 passage is 1-3/4 inch only. For a 2-1/4 inch door needing a passage function instead, the Falcon K101 covers 1-3/8 inch to 2-1/4 inch.
9) What replaces the Accentra 5403LN Augusta on a patient room or holding door that must not be lockable from inside?
The Accentra 5403LN Augusta locks from the inside by design, which is the opposite of what asylum and institutional openings want. The Dexter C1000 Series asylum function (F87) lever is Grade 1 for 1-3/8 inch to 2 inch doors and is keyed both sides with no inside locking device. The Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility lock with a ball knob and a conventional cylinder in Schlage C keyway.
10) Do I have to specify handing when ordering the Accentra 5403LN?
No. The 5403LN is non-handed and the strike is reversible, so one part number covers left and right hand openings. That simplifies stocking for a property manager carrying spares across a building.
11) Is a cylinder or keys included with the 5403LN?
No cylinder comes with the 5403LN because it is a non-keyed patio function. The brass 6-pin keyed-random cylinder with two keys that ships on the 5400 Series applies to the keyed functions in the family, not this one. If you need key access on the same door style, order a keyed 5400LN function instead.
12) What is the difference between the 5403LN patio lock and a standard privacy or passage lever?
Patio locks from inside only with no outside trim release. A passage lever, like the Falcon K101 or the Corbin Russwin CL3110, never locks at all and is for corridors and closets. A privacy lever, such as the Arrow MK02-TA, locks from inside but typically has an emergency release on the outside so staff can get in. Pick patio where you want no outside entry at all, privacy where you want an emergency unlock.
13) What is a Grade 1 alternative to the Accentra 5403LN if I need a thinner door range?
The 5403LN bottoms out at 1-3/4 inches. For a 1-3/8 inch door the Falcon K101 Grade 1 cylindrical lever covers 1-3/8 to 2-1/4 inches and is fire rated, though it is passage function rather than patio. The Dexter C1000 Grade 1 range also starts at 1-3/8 inches in several functions.
14) Does the 5403LN have a deadlocking latch so the bolt cannot be carded?
Yes. A guardbolt deadlocks the latchbolt whenever the door is closed, and it is standard on every locking function in the 5400 Series including the patio 5403LN. That is what stops a shimmed card from retracting the latch.
15) Can I order the 5403LN with a flat front instead of the beveled one?
Yes. The standard front is a 2-1/4 by 1-1/8 inch beveled face, and flat fronts are available to order for square-edge doors or existing flat-front preps. Lead shielding is also an option to order for X-ray rooms and similar healthcare openings.
16) Which alternatives to the Accentra 5403LN Augusta also hold a Grade 1 rating for standardizing a facility?
The Accentra 5403LN Augusta is Grade 1 per ANSI/BHMA A156.2 Series 4000 and UL/cUL fire rated up to 3 hours. Grade 1 lever locks in other functions include the Falcon K101 passage (heavy duty, fire rated, 1-3/8 inch to 2-1/4 inch doors), the Falcon T101 passage, the Corbin Russwin CL3110 passage/closet (fire rated, 1-3/4 inch to 2 inch), the Dexter C1000 asylum function for 1-3/8 inch to 2 inch doors, and the Design Hardware X75 passage lever for 1-3/4 inch doors. That gives a Grade 1 set across passage, privacy and institutional openings.
17) Is there a lower-grade privacy lever that can be used instead of the Accentra 5403LN Augusta on light-traffic doors?
Yes. The Accentra 5403LN Augusta is an ANSI/BHMA A156.2 Series 4000 Grade 1 cylindrical lever with a 2-3/4 inch backset and 1-3/4 inch to 2-1/4 inch door thickness range. For lighter duty, the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever and a 1-3/8 inch to 2 inch door range. The Kwikset 300BRNL Breton is a Grade 3 privacy lever set for 1-3/8 inch to 1-3/4 inch doors. Note the narrower door thickness coverage on both compared with the 5403LN.
18) Does a knob-style privacy lock work as a substitute for the Accentra 5403LN Augusta?
Only if lever operation is not required. The Accentra 5403LN Augusta uses the Augusta lever handle. The Arrow MK02-TA is a privacy/bed/bath cylindrical lock with a Tudor knob, fire rated, for 1-3/4 inch to 2 inch doors. A knob trim changes the ADA and accessibility picture on many commercial openings, so confirm the opening allows knob trim before swapping.
19) Is there a keyless pushbutton lever to use in place of the Accentra 5403LN Augusta where codes replace keys?
The Accentra 5403LN Augusta is a mechanical non-keyed patio/privacy lever. If code entry is the goal, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function, ADA compliant, for 1 3/16 inch to 2 inch doors, and the Lockey 2835DC adds double combination on the same door range. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination for 1-1/8 inch to 2 inch doors. These are code-operated rather than an inside privacy turn.
20) What finishes does the Accentra Augusta 5403LN come in?
Nine finishes are orderable: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, plus black suede and white suede powder coat. PVD is standard on 605 and 606, so those two hold up better against handling and cleaning chemicals than a plated equivalent.
