Delaney Hardware 3C5040 – Frequently Asked Questions
1) What does the storeroom function on the Delaney F Series SD lever actually do?
Outside lever is always locked. Entry from outside is by key only, turning the key in the outside lever retracts the deadlocking latch bolt. The inside lever always rotates freely for exit, so nobody gets trapped in the room. That is the standard setup for storage rooms, mechanical closets, and utility spaces that must stay locked at all times without anyone remembering to lock them.
2) What backset does the Delaney F Series storeroom lever come with, and can I get 2-3/8 inch?
It ships with the 2-3/4 inch UL latch as standard (F9070T for keyed functions) and a 2-3/8 inch latch is available as an option (F9060T). Both are the usual commercial backsets, so if your existing cross bore is centered 2-3/8 inches off the door edge, specify the optional latch rather than redrilling the door.
3) Can I drop this into the existing door prep on a lock I'm replacing?
If the door is prepped to the standard bored pattern, yes. The F Series needs a 2-1/8 inch cross bore, a 1 inch edge bore, and a 1-1/8 x 2-1/4 inch latch face mortise, which is the common commercial cylindrical lock prep. The frame side takes a 4-7/8 inch ANSI strike (9109), so if your frame has the older small 1-1/8 x 2-3/4 inch strike prep you will be filling or re-prepping the jamb.
4) Is this lever heavy duty enough for a school or hospital corridor?
It is a Grade 1 commercial lockset that meets and exceeds BHMA/ANSI A156.2 Series 4000, Grade 1 at 800,000 cycles, and it also meets Federal Standard FF-H-106C. Grade 1 is the top cylindrical lock grade, so it is the right class for high traffic institutional openings.
5) Which lever works on a 3-hour fire rated door, the Delaney F Series SD or the Cal-Royal INDLEV-20?
The Delaney F Series SD storeroom leverset ships with a 1/2 inch stainless steel throw latch bolt that meets a 3-hour fire rating, with a 2-3/4 inch UL latch as standard and a 4-7/8 inch ANSI strike (9109). The Cal-Royal INDLEV-20 is offered as a privacy indicator lever in 2-3/8 inch and 2-3/4 inch backset. For a rated corridor or stair door where the latch has to carry the fire rating, specify the Delaney F Series SD.
6) For a restroom or changing room that needs occupancy indication instead of key control, what lever should be used in place of the Delaney F Series SD storeroom lock?
The Delaney F Series SD lever is a storeroom function lock - the outside lever is always locked and the deadlocking latch is retracted by key outside or by turning the inside lever, so it controls access rather than signaling occupancy. For a restroom, changing room, or exam room where the door needs to be locked from inside and read at a glance, the Cal-Royal INDLEV-20 is a privacy indicator leverset with a red/green occupancy indicator. It is offered in 2-3/8 inch and 2-3/4 inch backset, which matches the bored prep the Delaney uses (2-3/4 inch UL latch standard, 2-3/8 inch optional).
7) Is the Cal-Royal INDLEV-20 an equivalent replacement for a Delaney F Series SD storeroom leverset?
No. They are different functions and different duty ratings. The Delaney F Series SD lever is a keyed storeroom lock that meets and exceeds BHMA/ANSI A156.2 Series 4000 Grade 1 at 800,000 cycles and also meets the FF-H-106C federal standard, which is what an institutional or MRO spec calling for Grade 1 storeroom hardware is asking for. The Cal-Royal INDLEV-20 is a privacy indicator lever rated standard duty commercial grade, with no key cylinder. Substituting it on a storeroom, janitor closet, or mechanical room door would remove key control from that opening.
8) Do I have to specify handing when I order this lever?
No. Handing is not required on the F Series SD leverset, so one part number covers left and right hand openings. That makes it easier to stock a single SKU across a building instead of splitting inventory by swing.
9) I need a restroom lever with an occupancy indicator, not a keyed storeroom lock. What should I look at?
The storeroom F Series is key-only from outside and has no indicator, so it is the wrong function for a restroom. For that, the Cal-Royal INDLEV-20 is a privacy leverset with a red/green occupancy indicator, available in 2-3/8 inch and 2-3/4 inch backsets and adjustable for 1-3/8 inch to 1-3/4 inch doors. Note it is a standard duty commercial lock rather than Grade 1, so on a high traffic public restroom weigh the indicator against the duty rating.
10) Does this come with a strike, and what else do I need to finish the install?
The F Series SD storeroom lever is supplied with the 4-7/8 inch ANSI strike (9109) as standard along with the 2-3/4 inch latch. Mounting uses removable through bolts, so no separate mounting kit is needed. What you do need to sort out separately is keying, since the storeroom function is key operated from the outside and normally gets keyed into the building's existing system.
11) Can both the Delaney F Series SD lever and the Cal-Royal INDLEV-20 be used on the same 2 inch thick door?
Only the Delaney will cover that thickness. The Delaney F Series SD leverset fits doors from 1-3/8 inch to 2 inch using an adjustable mounting plate. The Cal-Royal INDLEV-20 adjusts from 1-3/8 inch to 1-3/4 inch. On a thicker commercial door up to 2 inch, the Delaney F Series is the one that accommodates it; both will fit a standard 1-3/4 inch door.
12) I need to standardize levers across a building with both storeroom and restroom doors - do the Delaney F Series SD and Cal-Royal INDLEV-20 use the same door prep?
Both are cylindrical bored levers using a standard bored prep, so the openings are compatible in backset terms: the Delaney F Series SD uses a 2-1/8 inch cross bore, 1 inch edge bore and 1-1/8 inch by 2-1/4 inch latch face with 2-3/4 inch standard or 2-3/8 inch optional backset, and the Cal-Royal INDLEV-20 is supplied in 2-3/8 inch and 2-3/4 inch backset. Note the Delaney F Series is a Grade 1 keyed storeroom lever and the Cal-Royal is a standard duty commercial privacy indicator lever, so the two cover different door functions within the same program and the lever styles and finishes are not the same family.
13) What keeps the lever from being forced or sagging over time?
The F Series chassis uses an independent torsion spring to hold lever return, plus a clutch that makes the lever panic proof on the push/turn action, so force on a locked outside lever turns the clutch instead of loading the retractor. An anti-friction latch retractor is used on the latch side. Mounting is by removable through bolts with concealed screws.
14) What finish is this Delaney storeroom lever, and will it match my other oil rubbed bronze hardware?
It is US10B oil rubbed bronze. US10B is a living finish designation, so expect it to darken and wear at touch points over time rather than stay uniform, which is worth knowing if you are matching it against hardware that has already been in service for years.
