Delaney Hardware 329522 – Frequently Asked Questions
1) Will this Delaney classroom lever drop into an existing 2-1/8 inch bored door prep?
Yes. The RH Series MD lever uses a standard 2-1/8 inch cross bore with a 1 inch edge bore and a 1 x 2-1/4 inch latch face, so it goes into the prep left by most cylindrical locksets. The latch faceplate is 1 x 2-1/4 inch with round corners, and the strike is a 1-1/8 x 2-3/4 inch T-strike (9101).
2) How does the classroom function work on this Delaney lever, and who can lock the door?
Outside lever is locked and unlocked by key only, from the corridor side. There is no way to lock it from inside the room, and the inside lever is always free for egress. The latch bolt is deadlocking, and it retracts with the key in the outside lever or by turning the inside lever. If your district wants teachers to lock from inside the room during a lockdown, this is not the function for that.
3) What keyway options are there on the Delaney RH classroom lock, and can I key it into my existing Schlage or Kwikset keys?
Three keyways are orderable: SC4 6-pin as the standard, SC1 5-pin, or KW1 5-pin. SC1 and SC4 are Schlage keyways and KW1 is the Kwikset keyway, so you can match the cylinders to whichever system the building already runs. Keying is specified at order time as keyed different or keyed alike.
4) Is the Delaney RH classroom leverset rated for a school corridor or other high traffic door?
It meets BHMA/ANSI A156.2 Series 4000 Grade 2 at 400,000 cycles, which is the commercial medium-duty tier. Fine for classrooms, offices, and most institutional interior doors. For heavy-abuse entrances taking constant traffic you would step up to a Grade 1 cylindrical lock instead.
5) For a restroom or single-occupancy room that needs privacy rather than a keyed lock, what should I use instead of the Delaney RH Series MD classroom leverset?
The Delaney RH Series MD lever is a classroom function lock: the deadlocking latch is operated by key in the outside lever, and the outside lever is locked or unlocked only by key, with the inside lever always free. That is built for a room a staff member secures from the corridor, not for a restroom where the occupant locks from inside. For that opening, the Cal-Royal INDLEV-20 is a privacy indicator leverset with a red/green occupancy indicator, so the person outside can see whether the room is in use. Both share the same 2-3/8 inch and 2-3/4 inch backset coverage, so the door prep carries over.
6) Do I have to specify handing when I order the Delaney RH Series lever?
No. Handing is not required on the RH Series MD leverset, so one part covers left and right hand openings. That makes it easier to stock a few spares across a building without worrying about which way each door swings.
7) I need a lock for a restroom, not a classroom. Is this the right Delaney lever?
No. The RH Series MD here is a keyed classroom function, locked only by key from outside with no inside locking. For a restroom or single-occupancy room you want a privacy function. The Cal-Royal INDLEV-20 is a privacy leverset with a red/green occupancy indicator, adjustable 2-3/8 and 2-3/4 backset, fitting doors 1-3/8 to 1-3/4 inches.
8) Will the 1/2 inch throw latch on this Delaney lever work with the strikes already in my frames?
The bolt throws 1/2 inch and ships with a 1-1/8 x 2-3/4 inch T-strike (9101), which is the common bored-lock strike size in commercial hollow metal frames. If your frames are cut for an ANSI 1-1/4 x 4-7/8 inch strike, you will need to change the strike or the frame prep.
9) Is the Delaney RH Series lever panic proof for egress out of a classroom?
Yes. Turning the inside lever retracts the latch even when the outside is locked, so anyone in the room gets out in one motion. Delaney lists the RH Series as panic proof with the inside lever always unlocked.
10) Is the Cal-Royal INDLEV-20 a keyed substitute for the Delaney RH Series MD classroom lever?
No. The Cal-Royal INDLEV-20 is a privacy function lever with an occupancy indicator, so it has no keyed cylinder for corridor-side control. The Delaney RH Series MD is a Grade 2 classroom lock that takes an SC4 6-pin cylinder standard, with KW1 5-pin and SC1 5-pin options, and can be ordered keyed alike or keyed different. If the opening has to be secured by key from outside, the Cal-Royal is not an equivalent.
11) For a school corridor door that has to meet a commercial cycle spec, which of these levers is graded for it?
The Delaney RH Series MD classroom tubular leverset meets BHMA/ANSI A156.2 Series 4000, Grade 2, at 400,000 cycles, and its latch bolt carries a 3-hour fire rating. The Cal-Royal INDLEV-20 is described as standard duty commercial grade. Where a drawing calls out an ANSI Grade 2 cylindrical classroom lock by number, the Delaney is the one stating that certification.
12) What finish is the Delaney RH Series MD leverset, and will it match my other satin chrome hardware?
Finish is US26D dull chrome, the satin chrome finish used across most commercial door hardware, so it sits alongside existing US26D closers, hinges, and exit devices.
