Schlage L9457R17A626 – Frequently Asked Questions

1) How does the Schlage L9457 classroom security function actually work at the door?
The L9457 is a double-cylinder classroom security lock. A key from either side throws the deadbolt, and throwing it locks the outside lever. The latchbolt retracts from either side, and turning the inside lever pulls back both the deadbolt and the latchbolt while also unlocking the outside. The inside is always free, so a teacher can lock the corridor side from inside the room without stepping into the hallway, and nobody gets trapped in.
2) Is the Schlage L9457 mortise lock approved for a fire-rated door?
Yes. The L9000 series body, which the L9457 uses, is UL listed for 3-hour fire doors, and UL/cUL listed for A label single doors up to 4 ft x 10 ft and pairs up to 8 ft x 10 ft. The letter F and the UL symbol stamped on the latch front are how you confirm the listing on the part in hand.
3) What ANSI grade does the Schlage L9457 carry, and does the interchangeable core change it?
The L9000 series is tested and certified under ANSI/BHMA A156.13 as Grade 1 for both security and operational, and also meets ANSI/ASTM F476-76 Grade 40. One caveat matters for spec writers: with interchangeable core cylinders the security rating is Grade 2, while a concealed shell cylinder holds A156.13 Grade 1 operational and security. Since the L9457R is supplied with a large format interchangeable core, expect the Grade 2 security figure on the cylinder side.
4) Does the Schlage L9457 mount in the door face or the door edge?
It is a mortise lock: the lock body sits in a pocket mortised into the edge of the door, not in a pair of bored holes through the face. That means the door needs a mortise pocket and edge prep, so it is not a drop-in for a cylindrical lock opening without changing the door prep.
5) What does the R suffix on a Schlage L9457R mean when I order?
The R indicates the lock is set up for a large format interchangeable core cylinder, the removable-core type a locksmith can rekey by pulling the core with a control key rather than servicing the whole cylinder. That is what makes it practical to standardize a school or campus on one keying system and swap cores as staff change.
6) Can I get a high-security cylinder in the Schlage L9457?
Yes. A UL437 listed locking cylinder is an option on the L series; specify a Schlage Primus 20-500 Series cylinder when you order if you need key control and drill and pick resistance beyond the standard core.
7) Does the Schlage L9457 meet ADA and California accessibility requirements?
The L series meets ADA requirements, and for the California Referenced Standards Code, all levers with a return to door of 1/2 inch (64 mm) or less comply. If your project is under CBC, pick a lever style with that return.
8) Will the Schlage L9457 qualify on a federal or public agency job with domestic sourcing requirements?
It meets the Buy American Act, and Schlage L series holds Miami-Dade NOAs and Florida Building Commission listings, which covers the usual hurdles on federal, state and Florida coastal work.
9) I have older Schlage L series classroom locks. Can I get classroom security function without replacing the whole lock?
Schlage publishes L Series classroom upgrade (conversion) kits for converting existing L series locks to the classroom security arrangement, which is the route to take when the mortise pockets and trim are already in the doors and you only need the function changed. If the doors are not already prepped for a mortise lock, the complete L9457R is the correct buy.
10) What finish does the Schlage L9457R classroom security mortise lock come in?
It is supplied in 626 Satin Chrome, the brushed chrome plating that is the common institutional match for school and healthcare corridor hardware.
11) Is the electrified version of the Schlage L series listed for access control on a single door?
Electrified L series functions are UL19X listed for single-point locking applications. Note the L9457 itself is the mechanical double-cylinder classroom security lock, so if you need the opening tied into access control you are ordering an electrified L9000 function instead.
