Schlage B571 One-Sided Deadbolt with Occupancy Indicator

The B571 is a Grade 2 bored deadbolt with a thumbturn-operated occupancy indicator.

Suited for restrooms, dressing rooms, and single-occupancy spaces in commercial and institutional applications.

    Schlage B571 626 – Frequently Asked Questions

    1) Can a Schlage B571 occupancy indicator deadbolt go on a fire rated door?
    UL 10B/UL 10C listing is available on the B571 as an auxiliary lock. You confirm it on the part rather than the box: a letter F and the UL symbol are marked on the latch front. That listing rides on the fire rated latch option, not the standard adjustable 12-288 latch, so it has to be specified when you order. If you'd rather buy the rating already settled in one part, the Hager 3216 thumbturn by occupancy indicator deadbolt, 1 inch throw, is listed as fire rated, though it fits 1-3/4 inch doors only.
    2) Will the Schlage B571 indicator deadbolt fit a 1-3/8 inch door or a 1-7/8 inch door?
    Both. The B571 covers 1-3/8 to 1-7/8 inch door thickness, which is a wider range than most indicator deadbolts. That top end is the reason to reach for it: on built-up or older institutional doors that measure over 1-3/4 inches, the cross-brand alternatives run out. The Accentra D292 and Arrow E50 indicator deadbolts are rated 1-3/8 to 1-3/4 inches, and the Hager 3216 is a 1-3/4 inch door only. Under 1-3/8 inches, none of them apply.
    3) My restroom doors are bored for a 2-3/8 inch backset. Do I have to order the Schlage B571 a different way?
    No. The B571 ships with the 12-288 latch, adjustable between 2-3/8 and 2-3/4 inch backset, with a lock-in-place helix so it holds the setting once adjusted. One part number covers both of the standard bored preps, which is what you want when a building's doors were prepped by different crews over the years. A 5 inch fixed backset latch and a fire rated latch are offered as separate options if the prep calls for them.
    4) Can anyone unlock a Schlage B571 from the corridor side if someone is stuck in the restroom?
    No, and that's the point of the function. There is no exterior key cylinder on the B571. The corridor side is an indicator plate only, reading Vacant or Occupied; the interior thumbturn is the sole thing that throws and retracts the bolt. If your facility needs staff override, this is the wrong function. Within the same Schlage B500 family, the B560 gives you thumbturn inside by cylinder outside, and the B563 classroom deadbolt lets the thumbturn retract only, with a cylinder outside. If you want the indicator and the override in one lock, the Falcon H2171 public restroom interconnected lock pairs an occupancy indicator with a single cylinder deadbolt.
    5) Should I use an indicator deadbolt or a privacy lever with a status indicator on a public restroom door?
    Depends on what else is on the door. The B571 is a bolt only. It has no latch and no handle, so the door needs a push plate and pull, or a separate passage set, to operate. That's the standard commercial restroom arrangement and it's why the deadbolt is one-sided: privacy from inside, status from the corridor. If the door has nothing else on it and you want one prep to do both jobs, go to a lever with a built-in indicator instead: the Corbin Russwin CLX3320 NVSL is a Grade 1 privacy visual status lever for 1-3/4 to 2 inch doors and is fire rated, and the Accentra AUYPL02 YPL Series is a Grade 1 privacy cylindrical lock with visual status indicator.
    6) What else can I buy instead of the Schlage B571 if I need a thumbturn and occupancy indicator deadbolt?
    By function, the closest is the Falcon D271, Grade 2, one-sided, medium duty, D200 Series. Cross-brand, the Accentra D292 is a Grade 2 cylindrical deadbolt with thumbturn and indicator for 1-3/8 to 1-3/4 inch doors, and the Arrow E50 is a non-keyed Grade 2 exit deadlock with a Vacant/Occupied indicator outside, same 1-3/8 to 1-3/4 inch range. Cal-Royal's IND90 with ADA thumbturn is another thumbturn by indicator deadbolt. One thing to check first: the D292, E50 and 3216 all top out at 1-3/4 inch doors, so on a thicker door the B571's 1-7/8 inch capacity is what makes the difference.
    7) What replaced the Schlage B571 one-sided deadbolt with occupancy indicator?
    The Falcon D271 is the replacement for the Schlage B571. The two line up closely: the D271 is a Grade 2 deadbolt with occupancy indicator, thumbturn inside function, and is a medium duty D200 Series device, while the B571 is a Grade 2 medium duty deadbolt with a one-sided lock function and the same thumbturn-inside, indicator-outside arrangement with no exterior key cylinder. For a restroom or dressing room opening already carrying a B571, the D271 is the same functional device from the same one-sided, non-keyed family.
    8) What is the closest equivalent to a Schlage B571 occupancy indicator deadbolt from another manufacturer?
    Three peers carry the same thumbturn-inside, indicator-outside deadbolt function at the same grade. The Accentra D292 is a Grade 2 cylindrical deadbolt with thumbturn and indicator function in the D Series, fitting doors 1-3/8 inch to 1-3/4 inch. The Arrow E50 is a Grade 2 exit deadlock with a Vacant/Occupied indicator outside and no key cylinder, also 1-3/8 inch to 1-3/4 inch. The Hager 3216 is a Grade 2 thumbturn by occupancy indicator deadbolt with a 1 inch throw for 1-3/4 inch doors. The B571 itself is Grade 2 with a 1 inch bolt throw and an adjustable 2-3/8 inch or 2-3/4 inch backset, so on a standard 1-3/4 inch commercial door any of the three lands on the same opening.
    9) Which occupancy indicator deadbolt fits a door thicker than 1-3/4 inches?
    The Schlage B571 covers 1-3/8 inch through 1-7/8 inch door thickness, so it reaches past the 1-3/4 inch mark on its own. Among the indicator peers, the Accentra D292 and the Arrow E50 are both listed for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3216 is listed for 1-3/4 inch. If the opening runs to a full 2 inches, the Corbin Russwin CLX3320 NVSL is listed for 1-3/4 inch to 2 inch doors, but it is a Grade 1 privacy lever lock with a visual status indicator rather than a deadbolt, so it replaces the door's latching hardware instead of adding a separate bolt.
    10) Which indicator lock works on a fire-rated restroom door?
    The Schlage B571 has a UL 10B and UL 10C listing available as an auxiliary lock, with the letter F and the UL symbol on the latch front identifying a listed unit, and fire-rated latch options are part of the B500 backset offering. Among the peers, the Hager 3216 Grade 2 thumbturn by occupancy indicator deadbolt carries a fire rating, and the Corbin Russwin CLX3320 NVSL Grade 1 privacy lever lock with visual status indicator does as well. The Hager stays in the deadbolt format the B571 uses; the Corbin Russwin is a lever lockset, so it changes how the door operates as well as how it indicates.
    11) What should I use on a public restroom where housekeeping needs key access from the corridor?
    The Schlage B571 will not do that job, because the thumbturn is the only operator and there is no exterior key cylinder on the indicator side. The Falcon H2171 is built for that case: a Grade 2 public restroom interconnected lock with occupancy indicator and a single cylinder deadbolt, in the H2 Series with a storeroom and public restroom function, so the corridor side carries both the indicator and a keyed cylinder. Use the B571 where occupants alone control the bolt, and the H2171 where staff need to key in.
    12) Will the Schlage B571 line up with the deadbolt strike already cut into my frame?
    The standard strike is the 10-094, square corner, 1-1/8 x 2-3/4, and the bolt throws 1 inch from a 1 inch diameter housing. The latch faceplate is 1 x 2-1/4 with square corners. If your existing frame is cut for a round corner strike, an ANSI strike, or a thimble strike, all three are offered, so an old prep usually does not have to be re-cut, only re-strike-plated. On a wood frame, the metal dust box reinforcer anchors with three 3 inch screws into the stud behind the jamb.
    13) Does the Schlage B571 meet ADA and Buy American requirements for a government or school restroom?
    Both. The thumbturn is an ADA compliant design, which is what an inspector looks at on a restroom door where the occupant has to operate the lock without tight grasping or twisting. It is BAA compliant for Buy American Act jobs, and it's certified to ANSI/BHMA A156.5 Grade 2. That combination is the usual spec floor for institutional single-occupancy restrooms and dressing rooms.
    14) Is a Grade 2 indicator deadbolt tough enough for a high traffic public restroom?
    The B571 is ANSI/BHMA A156.5 Grade 2 and rated medium duty, which is the normal commercial spec for restroom, dressing room and single-occupancy doors. Where the opening takes real abuse (a transit facility, a stadium, a high school), the step up in what we carry is a Grade 1 indicator lock: the Corbin Russwin CLX3320 NVSL extra heavy duty visual status lever or the Accentra AUYPL02 YPL Series privacy lock. Going the other direction, the Cal-Royal IND84 is a Grade 3 indicator deadbolt, light duty, which is not what you want on a public opening.
    15) With no cylinder on the outside, how is the Schlage B571 protected from being forced from the corridor?
    Four things do the work. The bolt is solid zinc with a hardened steel anti-saw pin insert. The collar spins free, so a wrench or pliers can't get purchase on it. A removable security shield blocks an ice-pick attack driven through the door at the bolt. And the metal dust box anchors into the frame with three 3 inch screws, which is what stops a wood jamb splitting under a kick. Set expectations honestly, though: with a 1 inch throw and a Grade 2 rating, this is an auxiliary privacy bolt, not an entrance-door security deadbolt.
    16) Are the Emtek thumbturn privacy bolts with indicator a substitute for a Schlage B571?
    Not for a commercial opening. The Emtek 8383 Wilshire, 8483 Watford, 8583 Square and 8683 Disk are thumbturn privacy bolts with double rosettes and an indicator, meant to be used alongside a brass passage set, which is a residential trim arrangement. The B571 is a Grade 2 commercial bored deadbolt: one-sided, indicator plate on the corridor face, no trim on the outside at all. If your spec calls Grade 2 or a Buy American compliant part, the Emtek bolts don't answer it.
    17) The specification calls for Grade 1 hardware with a visual occupancy indicator - what meets that?
    The Schlage B571 is certified to ANSI/BHMA A156.5 Grade 2, so a Grade 1 line item points to a different device type. The Corbin Russwin CLX3320 NVSL is a Grade 1 extra heavy duty privacy, bedroom and bathroom visual status lever lock in the CLX3300 Series, and the Accentra AUYPL02 is a Grade 1 privacy cylindrical lock with visual status indicator in the YPL Series. Both put the latch and the status indication in a single lockset operated by a lever or knob, where the B571 is a bolt that works independently of whatever passage hardware is already on the door.
    18) How does the Cal-Royal IND84 compare to the Schlage B571 indicator deadbolt?
    Both are indicator deadbolts driven by a thumbturn, and both show status on the opposite face. They sit at different certification tiers: the Cal-Royal IND84 is a Grade 3 indicator deadbolt with a thumbturn by indicator function, while the B571 is certified to ANSI/BHMA A156.5 Grade 2 and is rated medium duty for commercial use. Grade 3 is a lighter test tier, which matters most on doors that cycle heavily, such as a lobby restroom, versus a dressing room or a single-occupancy office.
    19) Can an Emtek thumbturn privacy bolt be used in place of a Schlage B571?
    They are not the same class of device. The Emtek 8383 Wilshire, 8483 Watford, 8583 Square, and 8683 Disk are thumbturn privacy bolts with double rosettes and an indicator, and each is meant to be used with a brass passage set as a decorative pairing. The Schlage B571 is a commercial medium duty Grade 2 bolt with an adjustable 2-3/8 inch or 2-3/4 inch backset, a metal dust box reinforcer anchored with three 3 inch screws, and a zinc bolt with a hardened steel anti-saw pin. If the opening is being specified for commercial traffic and code review, the Emtek bolts are trim-matched privacy hardware rather than a drop-in for the B571.
    20) Which occupancy indicator deadbolts have an ADA compliant thumbturn?
    The Schlage B571 uses an ADA compliant thumbturn design, so the bolt and the Vacant/Occupied indication can both be operated without tight grasping or twisting. The Cal-Royal IND90-G2 is the peer that states the same thing in its own description, an indicator deadbolt with an ADA thumbturn and a thumbturn by indicator function. For an accessible single-occupancy restroom where the bolt is the only operator the occupant touches, those two are the pair to weigh.
    21) How do you hold a B571 restroom door unlocked for cleaning or during setup?
    The thumbturn has a hold-back that keeps the bolt retracted. Set it and the door stays free swinging with the exterior plate reading Vacant, so housekeeping isn't fighting the lock and nobody gets shut out of a room being turned over. Throwing the thumbturn again drops the bolt and flips the plate to Occupied.
    22) What finishes does the Schlage B571 indicator deadbolt come in, and which matches standard commercial door hardware?
    Eight finishes: 605 bright brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, and 626 satin chrome. For a commercial or institutional building, 626 satin chrome is the standard, and it's what most closers, push plates and levers already on the doors will be. 613 oil rubbed bronze and 622 matte black are the ones to pick when the restroom trim is being matched to a hospitality or design package rather than the building standard.

      Privacy and Security Combined!

      Posted by Olivia on Jul 7th 2023

      Hey, I'm Olivia, and I recently purchased the Schlage B571 Door Bolt with Occupancy Indicator Grade 2 Deadbolt from ZenSupply. One thing I really love about this product is the built-in occupancy indicator that provides a clear visual indication of whether the room is occupied or not. It's a great feature for maintaining privacy and avoiding unwanted interruptions. However, the installation process can be a bit tricky, especially for those who are not experienced with door hardware. Overall, if you're looking for a reliable deadbolt that offers both security and privacy, the Schlage B571 Door Bolt is a solid choice.
