Delaney Hardware 3C6012 – Frequently Asked Questions
1) Will the Delaney F Series CT passage leverset fit a 1-3/8 inch interior door?
Yes. The F Series CT leverset mounts on doors from 1-3/8 inch up to 2 inch thick using an adjustable mounting plate, so it covers both older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors on the same part number.
2) What backset does this Delaney passage lever come with, and can it be used on a 2-3/8 inch bore?
It ships with the 2-3/4 inch UL latch as standard, and a 2-3/8 inch latch is available as an option. For the passage function the standard latch is the F9073T at 2-3/4 inch and the F9063T at 2-3/8 inch, so an existing door bored on either of the two common backsets can be covered.
3) What door prep do I need to drill for a Delaney F Series cylindrical leverset?
Standard cylindrical prep: 2-1/8 inch cross bore, 1 inch edge bore, and a latch face mortise of 1-1/8 by 2-1/4 inches with square corners. The strike is a 4-7/8 inch ANSI strike (9109). That is the same prep most commercial cylindrical locks already sit in, so retrofits usually need no new boring.
4) Is the Delaney F Series CT passage leverset Grade 1, and what cycle count does it meet?
It is a Grade 1 lock that meets and exceeds BHMA/ANSI A156.2 Series 4000, Grade 1, at 800,000 cycles, and it also meets the FF-H-106C federal standard. That combination is what institutional and government specs usually call for on corridor and classroom openings.
5) Can this passage lever go on a fire rated door?
The latch bolt is 1/2 inch stainless steel throw and meets a 3-hour fire rating, so the latching hardware is suitable for fire rated openings. Note the function itself has no locking mechanism, so on a fire door it provides latching only.
6) Passage or privacy lever for a restroom or closet door?
Passage is the right pick only where nothing needs to lock: both levers stay free at all times, which suits hallways, closets, and any latch-only opening. For a restroom or anywhere an occupant needs to lock the door, use a privacy function instead. The Cal-Royal INDLEV-20 privacy leverset adds a red/green occupancy indicator and is available in 2-3/8 inch and 2-3/4 inch backsets.
7) Which lever handles a thicker door - the Delaney 3C6012 or the Cal-Royal INDLEV-20?
The Delaney F Series CT 3C6012 uses an adjustable mounting plate covering 1-3/8 inch through 2 inch doors. The Cal-Royal INDLEV-20 adjusts from 1-3/8 inch to 1-3/4 inch. On a 2 inch leaf, the Delaney is the one dimensioned for it.
8) Do I have to specify handing when ordering this Delaney lever?
No handing required. The CT style passage leverset is non-handed, so one part works on left or right hand doors and you do not need to record swing direction when standardizing across a building.
9) Will a 1/2 inch throw latch engage my existing commercial strike?
The bolt throws 1/2 inch, which is standard for cylindrical latches, and it is supplied to work with the 4-7/8 inch ANSI strike (9109). If your frame already has a 4-7/8 inch ANSI strike cutout, the latch drops straight in.
10) How does the Delaney F Series compare to the Cal-Royal INDLEV-20 on door thickness?
The Delaney F Series CT covers 1-3/8 inch through 2 inch doors with its adjustable plate. The Cal-Royal INDLEV-20 is listed as adjustable 1-3/8 inch to 1-3/4 inch, so on thicker doors above 1-3/4 inch the Delaney is the one that still fits. The Cal-Royal is also a privacy indicator lock rather than a passage set, so they are not function-for-function substitutes.
11) Can I use this passage lever on a back entry door if I add a deadbolt?
Yes, that is a common pairing. Because the passage set only latches and never locks, it is often installed with a separate deadbolt above it to secure a back door or entrance while the lever stays free on both sides.
12) Will this lever break if someone hangs on it or forces it in a school corridor?
The CT lever uses a clutch function that is panic proof, push/turn, so force applied to the lever is not transmitted straight into the mechanism. It also uses an independent torsion spring to hold the lever level, plus an anti-friction latch retractor. Those are the features that keep a lever from sagging under heavy traffic.
13) Is the Cal-Royal INDLEV-20 a direct substitute for the Delaney F Series CT passage lever?
No. They differ in function: the Delaney F Series CT 3C6012 is passage, while the INDLEV-20 is a privacy leverset with indicator. They also differ in duty rating - the Delaney is ANSI/BHMA Grade 1 and the Cal-Royal is listed as standard duty commercial. Both are cylindrical bored levers, so the door prep is similar, but swapping one for the other changes how the door operates.
14) For a high-traffic corridor door, is there a heavier-duty lever than the Cal-Royal INDLEV-20?
Yes. The Delaney F Series CT 3C6012 passage leverset meets and exceeds BHMA/ANSI A156.2 Series 4000 Grade 1 at 800,000 cycles and also meets FF-H-106C, where the Cal-Royal INDLEV-20 is rated standard duty commercial. The Delaney is passage only, so use it where no locking is needed on the corridor leaf.
15) What finish is the Delaney 3C6012 leverset, and will it match my other satin chrome hardware?
Model 3C6012 is US26D Dull Chrome, the satin chrome finish specified on most commercial openings, so it lines up with existing US26D levers, closers, and exit hardware in a standardized building.
16) Are the mounting screws on this Delaney leverset visible after install?
No. The F Series CT uses concealed mounting screws with removable through bolts, so the rose faces show clean once the lever is set, and the through bolts still let you pull the set for service without damaging the trim.
