Delaney Hardware 3N5042 – Frequently Asked Questions
1) What does the storeroom function on the Delaney F Series MD lever actually do?
The outside lever is always locked. A key in the outside lever retracts the deadlocking latch bolt, and the inside lever always retracts it freely for egress. There is no way to leave the outside lever unlocked, which is why this function gets used on storage rooms, electrical closets, and mechanical spaces that must never be left open.
2) Will a Delaney F Series MD leverset fit a 1-3/8 inch door?
Yes. The F Series MD lever covers 1-3/8 inch through 2 inch doors using an adjustable mounting plate, so it handles both older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors without a separate kit.
3) What door prep does this cylindrical leverset need?
Standard 161 style bored prep: 2-1/8 inch cross bore, 1 inch edge bore, and a latch face mortise of 1-1/8 x 2-1/4 inches with square corners. If the door already has that prep from another cylindrical lock, the F Series MD drops in.
4) Does the Delaney F Series lever come with a 2-3/4 inch backset or 2-3/8 inch?
The 2-3/4 inch UL latch ships as standard; 2-3/8 inch is the option you have to call out. For the keyed entrance style latch that means F9070T at 2-3/4 inches and F9060T at 2-3/8 inches. Measure from the door edge to the center of the cross bore before you order.
5) I need a lever for a restroom or exam room door that shows occupied at a glance - is the Delaney F Series MD storeroom lever the right choice?
No. The Delaney F Series MD style lever is a keyed storeroom function: the outside lever is always locked and is released only by key, while the inside lever always retracts the deadlocking latch. There is no thumbturn and no occupancy indication. For a restroom or exam room where occupancy needs to read from the corridor, the Cal-Royal INDLEV-20 is the lever built for that job - it is a privacy function leverset with a red/green occupancy indicator, and it is offered in both 2-3/8 inch and 2-3/4 inch backsets so it drops into the same bored prep.
6) Do I need to specify handing for this Delaney leverset?
No handing required. The F Series MD lever is non-handed, so one part number covers left and right hand openings, which simplifies stocking it for a building with doors swinging both ways.
7) Is this lever strong enough for a high traffic school or hospital corridor door?
It is built for that use. Grade 1 at 800,000 cycles, an anti-friction latch retractor, an independent torsion spring so the lever does not sag, and a clutch mechanism that is panic proof push/turn, meaning force on a locked outside lever turns the clutch instead of breaking the spindle. The dull chrome US26D finish is the usual institutional standard.
8) I need a restroom lock, not a storeroom lock. Is this the wrong one?
Yes, wrong function. This one keeps the outside lever locked at all times, which nobody wants on a restroom. For a privacy application look at the Cal-Royal INDLEV-20 privacy indicator lever, which has a red/green occupancy indicator and covers 2-3/8 and 2-3/4 inch backsets on doors adjustable from 1-3/8 to 1-3/4 inches. Note it is a standard duty commercial grade lever rather than Grade 1.
9) Will a privacy indicator lever like the Cal-Royal INDLEV-20 work on the same doors as the Delaney F Series MD storeroom lever?
They share the cylindrical bored-lock platform and both cover the common 2-3/8 inch and 2-3/4 inch backsets, so the door prep is comparable, but the door thickness ranges differ. The Delaney F Series MD lever uses an adjustable mounting plate covering 1-3/8 inch through 2 inch doors, while the Cal-Royal INDLEV-20 adjusts from 1-3/8 inch to 1-3/4 inch. On a door thicker than 1-3/4 inch, the Delaney is the one that fits. They are also different functions - keyed storeroom versus privacy with indicator - so they are not interchangeable on the same opening unless the function requirement changes.
10) For a high-traffic commercial corridor, is a standard duty lever enough or do I need the Delaney F Series MD?
Duty rating is where these separate. The Delaney F Series MD style leverset is Grade 1, meeting and exceeding BHMA/ANSI A156.2 Series 4000 at 800,000 cycles, and also meets the FF-H-106C federal standard - that is the tier institutional and MRO specs usually call out for corridor, stairwell and storeroom doors. The Cal-Royal INDLEV-20 is a standard duty commercial lever, suited to lighter-cycle interior openings such as single-occupancy restrooms. If the opening carries heavy daily traffic or the spec sheet says Grade 1, the Delaney is the one that meets it.
11) What finish is US26D and will it match my other door hardware?
US26D is dull (satin) chrome, the most common commercial finish on lever locks and the usual match for satin chrome closers, exit devices, and hinges already in a building. It is not polished chrome, so it will read flat next to bright US26 trim.
12) Are the mounting screws visible after installation?
No. The F Series MD lever uses concealed mounting screws with removable through bolts, so the rose faces show clean once installed and the lock can still be taken apart for service without cutting anything.
