Schlage 09-544 027 626 – Frequently Asked Questions
1) Will the Schlage 09-544 thumbturn fit a 1-3/4 inch commercial door?
Yes. The 09-544 thumbturn covers doors 1-3/8 to 1-7/8 inches thick, so a standard 1-3/4 inch commercial door sits right in the middle of the range. The same part also handles the older 1-3/8 inch interior door and doors built up to 1-7/8 inches. If your opening is thicker than 1-7/8, this is not the turn piece for it.
2) Will the 09-544 thumbturn work with my Schlage L Series lock trim?
It works with Schlage L Series sectional rose trim. That is the trim style where a separate round rose sits behind the lever and another behind the turn, rather than one long plate running down the door. Look at the turn side of your L Series lock: round rose, the 09-544 is the matching thumbturn. If the lock is trimmed with a full escutcheon plate, this part is not the one specified for it.
3) Is the 09-544 a complete lock or just the thumbturn piece?
Just the turn piece. The 09-544 is a replacement thumbturn for Schlage L Series sectional rose trim, so it addresses a broken or missing turn on a lock that is otherwise fine. If the rose itself, the lever, or the lock body is what failed, those are separate parts and this will not cover them. Order it when the lock still throws correctly and only the turn needs replacing.
4) Does the 09-544 thumbturn operate a privacy lock, or only a deadbolt?
Both. The 09-544 is built to drive deadbolt functions and privacy lock functions on Schlage L Series trim, which is why the same part number turns up on restroom and office privacy doors as well as on deadbolt-function mortise locks. What decides it for you is the trim, not the function: sectional rose trim on the turn side and a door in the 1-3/8 to 1-7/8 inch range.
5) Is the Schlage 09-544 thumbturn ADA compliant for a restroom or an accessible unit?
ADA compliant, yes. The 09-544 extends equally on the exterior and interior faces of the door, which is what meets the ADA lever and turn requirement. For a facility standardizing accessible restrooms or dwelling unit doors on L Series hardware, this is the turn piece that keeps the opening compliant when the original one breaks.
6) I need thumbturns to match the satin chrome Schlage hardware already in the building. What finish do I order?
Order 626 Satin Chrome. The 09-544 comes in nine commercial finishes: 605 Bright Brass, 606 Satin Brass, 619 Satin Nickel, 622 Matte Black, 625 Bright Chrome, 626 Satin Chrome, 629 Bright Stainless Steel, 630 Satin Stainless Steel, and 643E Aged Bronze. Those numbers are the standard BHMA finish codes, so 626 on the turn matches 626 on the levers and roses already hanging on your other doors. Pull the number off an existing piece of trim rather than matching by eye, because 625 bright chrome and 629 bright stainless read almost the same across a corridor.
7) What do I actually have to specify when ordering a Schlage 09-544 thumbturn?
Finish is the only choice on the order form, and there are nine of them, from 605 Bright Brass through 643E Aged Bronze. Everything else is a check you make at the door before you send the order: the lock has to be Schlage L Series with sectional rose trim on the turn side, and the door has to fall between 1-3/8 and 1-7/8 inches thick. Get those two right and the finish code is all that is left to pick.
8) My existing thumbturn broke but I do not know which Schlage trim I have. How do I tell whether the 09-544 is the right replacement?
Take the trim off and look at two things. First, the shape of the plate behind the turn: the 09-544 is made for L Series sectional rose trim, meaning a separate round rose on the turn side, not a single long escutcheon plate. Second, measure the door leaf. Anything from 1-3/8 to 1-7/8 inches thick is covered. Rose trim plus a door in that range means this thumbturn drops back into the same L Series application, in whichever of the nine finishes matches the rest of the trim.
9) Will a Schlage 09-544 thumbturn hold up on high traffic multifamily and institutional doors?
The 09-544 is a commercial-grade part with a stainless steel substrate, not a residential turn piece. That is the same material spec you want on restroom, corridor, and unit doors that get cycled all day. Stainless also gives you the 629 and 630 stainless finish options, which wear better than plated brass in wet or coastal locations.
