Sargent 28-7G05 LB 26D – Frequently Asked Questions

1) Will the Sargent 7G05 fit a 1-3/8 inch door, or does it need a 1-3/4 inch door?
The 7G05 cylindrical lever lock covers 1-3/8 inch through 1-3/4 inch doors, so it works on both older interior doors and standard commercial doors without a spacer kit. It goes into a modified 161 prep. Anything thicker than 1-3/4 inches is outside the range, and for a 2 inch door you would need a different lock family.
2) Which backset do I order for the Sargent 7G05, 2-3/8 or 2-3/4 inch?
Both backsets are offered on the 7G05, so measure from the door edge to the center of the existing bore before ordering. 2-3/4 inches is the usual commercial layout and 2-3/8 inches is the common residential-style layout. Matching the existing prep matters more than any rule of thumb, because a backset mismatch puts the lever in the wrong place relative to the stop.
3) What does the Entrance/Office function on the Sargent 7G05 actually do at the door?
Entrance/Office is the function where the outside lever can be locked and unlocked, typically by pushbutton, and the inside lever always retracts the latch for free egress. The 7G05 is keyed on the outside as a single cylinder lock, so staff can secure an office from inside and key back in from the corridor. If you need a lever that is always locked outside and only opens by key, a storeroom function is the right call instead.
4) Do I need to specify handing for the Sargent 7G05 lever lock?
No handing to specify. The 7G05 is non-handed, so one part number covers left and right hand openings, and a property manager stocking spares does not need to keep both. The lever style is a separate choice: B, L, or P.
5) Can I use a Sargent 7G05 on a fire rated door?
Fire door use is covered. The 7G05 is UL-cUL fire rated up to 3 hours, so it can go on a rated opening within that rating. It is also ADA compliant, which matters on any door in an accessible route, and the lever handle itself satisfies the operable-without-tight-grasping requirement.
6) What keying options can I get on a Sargent 7G05, and can I put it on my building master key system?
Master keying is available, along with keyed different, keyed alike, and standard keying, so the 7G05 can be brought onto an existing SARGENT system. Keyways run from LA standard through the CA, CB, CC, CE, CF, CG, CJ, CK, CL, CR, HA, HB, HC, HE, HF, HG, HH, HJ, HK, LB, LC, LE, LF, LG, LJ, LK, LL, R, RA, RB, RC, RE, RF, RG, RJ, RK, RL, S and U sections. It also works with the Degree, Signature, KESO and XC key systems. Supply your existing keyway and bitting information with the order so the locks arrive on system.
7) Can I order the Sargent 7G05 less cylinder or with a construction core for a job still under build?
Yes, and this is the usual play on new construction. Order LC (less cylinder) if your locksmith is supplying the cylinder, or take a disposable plastic construction core so the trades can work the building and the permanent cores go in at turnover. Two core formats are offered: 60 for SARGENT large format interchangeable (FSIC) and 70 for small format interchangeable (SFIC). Pick the format that matches the cores the rest of the facility already uses, or the cores will not swap.
8) What is the closest Grade 1 equivalent to the Sargent 7G05 entrance/office lever lock?
The Sargent 7G05 is an Entrance/Office cylindrical lever lock built to Grade 2. If the opening calls for Grade 1, the Dexter C1000 Series Entry/Office cylindrical lever lock covers the same Entrance/Office function at Grade 1 and fits doors 1-3/8 inch to 1-3/4 inch, the same door thickness range the 7G05 accommodates.
9) The Sargent 7G05 will not work on a door thicker than 1-3/4 inch. What entrance lever lock handles a thicker door?
The Sargent 7G05 accommodates door thickness from 1-3/8 inch to 1-3/4 inch. For a thicker leaf, the Hager 2525 is a Grade 2 commercial cylindrical entry lock covering 1-3/8 inch to 2 inch, and the Deltana 6201 Manchester Lever entry set also covers 1-3/8 inch to 2 inch.
10) I need an entrance lock keyed to a Schlage C keyway instead of a Sargent keyway. What is the option?
The Sargent 7G05 is offered in Sargent keyways including LA standard, plus the C, H, R, L, S and U families. If the building is standardized on Schlage C, the Cal-Royal AG00 is an entrance lever with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, for doors 1-3/8 inch to 1-3/4 inch.
11) Is a Grade 2 lock like the Sargent 7G05 enough for an office corridor, or should I be buying Grade 1?
Grade 2 is the standard duty tier, and the 7G05 exceeds ANSI/BHMA A156.2 for cycling and durability. That suits office doors, tenant suites, and interior traffic in schools and healthcare. For a high-abuse opening, a stairwell, or a door taking constant public traffic, step up to Grade 1 heavy duty: the Corbin Russwin CL3100 Series and the Falcon K Series are both Grade 1 heavy duty cylindrical locks, and the Dexter C1000 Series covers Grade 1 in an entry/office function like this one.
12) What is the closest equivalent to a Sargent 7G05 in another brand?
For a Grade 2 cylindrical lever in entrance/office function, the Falcon B511CP6D is the direct match, medium duty Grade 2 in the same function. The Hager 2525 is a Grade 2 commercial cylindrical entry lever covering 1-3/8 to 2 inch doors, which gives you more thickness range. On a tighter budget the Cal-Royal AUS00 is a Grade 3 entrance/office lever for 1-3/8 to 1-3/4 inch doors, one grade down from the 7G05. Where you want Grade 1 in the same function, the Dexter C1000 entry/office covers 1-3/8 to 1-3/4 inch.
13) Do I need to bore extra holes in the door for the Sargent 7G05 through-bolts?
No extra prep. The 7G05 uses internal through-bolts, so the added strength comes without any door preparation beyond the modified 161 prep the lock already needs. That is the difference from locks that through-bolt through the rose and require separate holes drilled through the door face.
14) I only need a lever on the door with no lock at all, is the Sargent 7G05 the wrong part?
Right, the 7G05 is a keyed single cylinder lock and always locks. For a door that just needs to latch and stay operable both sides, a passage function is what you want, such as the Falcon B101 or the Hager 2510, both Grade 2 cylindrical passage levers. For a pull with no latch at all on an inactive leaf or a closet face, a dummy trim like the BEST 7KC Series single dummy is the part.
15) I need a classroom or storeroom lever, not entrance/office. What should I look at instead?
The 7G05 is the entrance/office function only, so it is the wrong pick for those. For a classroom lever keyed outside, the Cal-Royal AG03 is a Grade 2 classroom lever with a 2-3/4 inch backset, and the Dexter C1000 classroom covers Grade 1 on 1-3/8 to 1-3/4 inch doors. For a storeroom lever that stays locked outside, the Cal-Royal AG05 is Grade 2 with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors, and the Hager 2580 is a Grade 2 storeroom lever for 1-3/8 to 2 inch doors.
16) What is a lighter-duty alternative to the Sargent 7G05 for an interior office door in a low-traffic building?
The Cal-Royal AUS00 is an Entrance/Office lever lock built to Grade 3, fitting doors 1-3/8 inch to 1-3/4 inch. It carries the same Entrance/Office function as the Sargent 7G05, which is a Grade 2 commercial lock. Choose by the cycle demand of the opening, since Grade 2 and Grade 3 are tested to different ANSI/BHMA levels.
17) Can a passage lever lock be used in place of the Sargent 7G05?
No. The Sargent 7G05 is keyed, with a single cylinder and a choice of Sargent keyways. A passage lockset such as the Falcon B101, a Grade 2 non-handed cylindrical passage lever, or the Accentra 5301LN Augusta, a Grade 2 passage/closet cylindrical lever, has no cylinder and never latches against a key. Those are for doors that only need latching, not securing.
18) Is a dummy lever an alternative to the Sargent 7G05 on the inactive leaf of a pair?
No. The Sargent 7G05 is a keyed cylindrical lock with a latchbolt. A dummy trim has no latch and no cylinder: the BEST 7KC Series single dummy trim is a Grade 2 non-keyed lever, and the BEST 9K Series 1DT is the Grade 1 heavy duty version. Use a dummy only where the leaf is held by flush bolts and needs a pull, not a lock.
19) What is a heavier alternative to the Sargent 7G05 for a high-abuse or vandal-prone opening?
The Sargent 7G05 is a standard duty Grade 2 lock. For harder use, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock, fire rated, for doors 1-3/4 inch to 2 inch, though it is a passage/closet function rather than a keyed entrance function. The Dexter C1000 Entry/Office is the Grade 1 option that keeps the Entrance/Office function.
20) What replaces the Sargent 7G05 where the opening needs keyless code entry rather than a key?
The Sargent 7G05 takes a key in a single cylinder. Where a code is wanted instead, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination, passage function, for doors 1-1/8 inch to 2 inch. The mechanical Lockey needs no power.
21) Is the Arrow HK11 a substitute for the Sargent 7G05?
Not directly. The Arrow HK11 is a Grade 2 turn-pushbutton entrance cylindrical lock with a conventional cylinder and covers doors 1-3/8 inch to 1-3/4 inch, the same thickness range as the Sargent 7G05, but it is a ball knob rather than a lever. The 7G05 is a lever set, offered with B, L, or P levers and ADA compliant.
22) What goes on a restroom or patient room door where the Sargent 7G05 is not the right function?
The Sargent 7G05 is a keyed Entrance/Office lock and is not a privacy set. For a bath or bed door, the Hager 2540 is a Grade 2 cylindrical privacy lock with the Withnell lever for doors 1-3/8 inch to 2 inch. For a patient or holding room, the Dexter C1000 asylum function is a Grade 1 cylindrical lock covering doors 1-3/8 inch to 2 inch.
23) What finishes does the Sargent 7G05 come in for matching the rest of my building?
Fifteen architectural finishes are available on the 7G05, covering brass in 03 bright and 04 satin, bronze in 09 bright, 10 satin, and the dark oxidized 10B oil rubbed, 10BE, and 10BL clear coated, plus 20D dark statuary bronze lacquered, nickel in 14 bright and 15 satin, chrome in 26 bright and 26D satin, and powder coats in BSP black and WSP white. 26D satin chrome is the common commercial default if you are standardizing a fleet of openings.
24) Is there an antimicrobial option for locks going into a hospital or a school?
Microshield antimicrobial coating is an available option on the 7G05, giving continuous protection against bacteria on the lever and rose, which are the high-touch surfaces. That is the specification to call out for patient rooms, clinics, and classroom corridors where infection control is part of the standard.
25) What entrance lever should go on a residential-style unit door if the Sargent 7G05 is more lock than the opening needs?
The Sargent 7G05 is a commercial Grade 2 lock. On lighter residential-style openings, the Callan Artino is a Grade 3 entrance leverset, and the Callan Bennett is a Grade 3 entrance leverset supplied as a deadbolt combo where a second point of security is wanted.
