Sargent 28LC-7G04 LB 26D – Frequently Asked Questions

1) What does storeroom function mean on the Sargent 7G04, and is it the right lock for a mechanical or supply room?
Storeroom/closet function is exactly what a locked supply room wants: the outside lever stays locked at all times and only the key retracts the latch. The inside lever always turns for free egress. There is no button or thumbturn to leave in the wrong position, so staff cannot accidentally leave the room unsecured. If you instead want the door to stay unlocked during the day and be locked by key when you leave, storeroom is the wrong function and you want an entry/office lock.
2) Do I have to specify handing when ordering a Sargent 7G04 lever lock?
No handing to specify. The 7G04 is non-handed, so one lock covers left and right hand doors and you do not need to know the swing before you order. That matters if you are buying a batch for a building and do not want to survey every opening. You do still choose the lever style: B, L, or P.
3) Can the Sargent 7G04 go on a fire rated door?
Yes. The 7G04 is UL-cUL fire rated up to 3 hours and NFPA 80 compliant, so it can be used on rated openings up to a 3 hour assembly. The storeroom function suits rated doors for the same reason it suits stairwells and utility rooms: the inside lever always releases the latch, so egress is never keyed. It also meets ADA and ICC A117.1 for lever operation.
4) Can I get the Sargent 7G04 keyed alike with the other locks in my building?
Yes. Keying options are keyed alike, keyed different, master keyed, standard keying, or supplied with no cylinder at all. Choose your keyway to match what is already in the building; 42 keyway choices are offered including LA as standard, plus the CA through CR, HA through HK, LB through LL, R series, RA through RL, S and U sections. If you are extending an existing Sargent master key system, order in that system's keyway and specify MK so the new locks pin into the same hierarchy.
5) Can I order the Sargent 7G04 less cylinder so I can use my own interchangeable core?
Yes. Cylinder options are LC less cylinder, a standard 6-pin cylinder, a 60 large format interchangeable core housing with a plastic disposable construction core, or a 70 small format interchangeable core housing with a disposable construction core. Facilities already running SFIC or LFIC should take the 60 or 70 so their own cores drop straight in. The construction core lets the trades use a throwaway key during the build, then you pull it and seat the permanent core at turnover without touching the lock body.
6) Is the Sargent 7G04 heavy duty enough for a school corridor or high traffic opening?
The 7G04 is a Grade 2, standard duty cylindrical lock. That is right for commercial interior doors, offices, closets and storage rooms with normal traffic. For a high abuse opening, a school corridor or a main entrance, step up to a Grade 1 heavy duty cylindrical lock such as the Falcon K Series or the Corbin Russwin CL3100 Series, both Grade 1. The internal through-bolts on the 7G04 do add pull-off resistance without any extra door prep, but they do not make it a Grade 1 lock.
7) What else could I use instead of a Sargent 7G04 for a Grade 2 storeroom lever?
Two straight peers sit in the same class. The Hager 2580 with the Withnell lever is a Grade 2 storeroom cylindrical lock covering 1-3/8 to 2 inch doors, so it reaches thicker doors than the 7G04's 1-3/8 to 1-3/4. The Cal-Royal AG05 is a Grade 2 storeroom leverset with a deadlocking latchbolt, rated 1-3/8 to 1-3/4 inch. The reason to stay with the 7G04 is the keying: the Sargent keyway sections and the SFIC or LFIC core options let it join an existing Sargent key system, which neither of the others will do.
8) My door is 2 inches thick. Will the Sargent 7G04 work?
No. The 7G04 tops out at 1-3/4 inches. For a 2 inch door look at the Hager 2510 or 2525, both Grade 2 and rated 1-3/8 to 2 inches, or the Arrow GL01 at 1-3/4 to 2 inches. If you need Grade 1 on a thick door, the Corbin Russwin CL3110 covers 1-3/4 to 2 inches and the Falcon K101 goes to 2-1/4 inches. Note that the Hager, Arrow and Falcon options named here are passage or entry function, not storeroom, so match the function separately.
9) The opening is a 2 inch thick door - what storeroom lever works there instead of the Sargent 7G04?
The 7G04 is built for doors 1-3/8 inch to 1-3/4 inch, so a 2 inch leaf is outside it. The Hager 2580 storeroom cylindrical lock with Withnell lever carries a door thickness range of 1-3/8 inch to 2 inch and holds the same Grade 2 rating and storeroom function. For a heavier door on a keyed opening of a different function, the Dexter C1000 asylum lock covers 1-3/8 inch to 2 inch at Grade 1, and the Falcon K101 passage covers 1-3/8 inch to 2-1/4 inch at Grade 1, though neither is a storeroom lock.
10) What is the closest Grade 2 storeroom lever lock to the Sargent 7G04 from another manufacturer?
The Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt, fitting doors 1-3/8 inch to 1-3/4 inch, the same door thickness range the 7G04 covers. The Hager 2580 is also a Grade 2 storeroom cylindrical lock with the Withnell lever, fitting 1-3/8 inch to 2 inch doors. Both hold the storeroom function like the 7G04, where the outside lever is always locked and a key retracts the latch. The 7G04 differs in that it takes Sargent keyways such as LA, and offers Sargent large format and small format interchangeable core options, so keying it into an existing Sargent master system is done with the lock itself rather than a cylinder swap.
11) Can I put a Sargent 7G04 on a classroom door instead of a classroom lock?
No - the 7G04 is storeroom/closet function, meaning the outside lever stays locked at all times and a key only retracts the latch, so an instructor cannot leave the door unlocked for a class period. For a keyed classroom opening, the Cal-Royal AG03 is a classroom lever in a 6-pin Schlage C keyway keyed different with a 2-3/4 inch backset, and the Dexter C1000 offers a Grade 1 classroom lever with clutching as well as a Grade 1 classroom security version. The 7G04 remains the right function for storage rooms, mechanical rooms and other spaces that must never be left unsecured.
12) What is the difference between the Sargent 7G04 and an entrance or office lever like the Hager 2525 or Falcon B511?
The 7G04 is a storeroom lock: the outside lever is permanently locked and there is no button or turn to leave it unlocked. The Hager 2525 is a Grade 2 cylindrical entry lock with a lever, and the Falcon B511CP6D is a Grade 2 medium duty entry/office lever - entry/office function lets an occupant unlock the outside lever and leave it free for the day. The Arrow HK11 is an entrance lock with turn-pushbutton control and a conventional cylinder on a ball knob. Choose the 7G04 where the door must relock every time it closes, and an entrance/office lock where staff need to hold the door unlocked during business hours.
13) Our building is keyed on Schlage C - does that rule out the Sargent 7G04?
The 7G04 is ordered in Sargent keyways including LA as the standard, plus the CA, HA, LB, R, S and U families, and can take a Sargent large format or small format interchangeable core. If the facility is standardized on Schlage C, the Cal-Royal AG00 entrance lever and AG03 classroom lever are supplied with a 6-pin Schlage C keyway keyed different, and the Arrow MK33 asylum lock uses a conventional cylinder in Schlage C. The other path is to order the 7G04 less cylinder and fit the cylinder your key system already uses.
14) The storage room needs to release on a fire alarm - can a Sargent 7G04 do that?
No. The 7G04 is a mechanical cylindrical lock with no electrical connection. For an opening tied to access control or an alarm release, the Corbin Russwin CL33903 is a Grade 1 fail safe electrified cylindrical lever running on 12VAC/DC, available with the NZ lever and D rose, and it fits doors 1-3/4 inch to 2 inch. Fail safe means the lever unlocks when power drops. Keep the 7G04 on openings where a mechanical key is the only control needed.
15) Does the Sargent 7G04 need extra door prep for the through-bolts?
No extra prep. The through-bolts on the 7G04 are internal, so they run inside the standard cylindrical bore and cross-bore rather than through separate holes drilled in the door face. A door already prepped for a 161 cylindrical lockset takes it as is, which is what makes this a clean swap on an existing opening.
16) What finishes does the Sargent 7G04 come in, and is there anything for a healthcare setting?
Fourteen finishes are offered, from bright and satin brass (03, 04), bright and satin bronze (09, 10), the dark oxidized bronze family (10B oil rubbed, 10BE, 10BL clear coated), 20D dark statuary bronze, bright and satin nickel (14, 15), bright and satin chrome (26, 26D), through to black and white suede powder coat (BSP, WSP). 26D satin chrome is the usual commercial default and the easiest to match across a building. For healthcare and food service, the 7G04 is also offered with Microshield antimicrobial coating.
17) I need to match the lever style on my other Sargent 7 Line doors. What levers are available on the 7G04?
Three lever designs: B, L and P. Whichever style is already on your other 7 Line openings can be carried across, so a storeroom door reads the same as the passage and office doors next to it. All three are non-handed and all meet the ADA lever requirement, so the choice is purely aesthetic, not functional.
18) Can I replace an old knob lockset with the Sargent 7G04 to meet accessibility rules?
That is a common reason to buy it. The 7G04 is a lever, and it meets ADA and ICC A117.1 requirements, so it takes an opening off a knob that no longer complies. Because it is a cylindrical lock in the standard bore, it goes back into the same hole an old knob lockset came out of. Confirm your backset (2-3/8 or 2-3/4 inch) matches the existing bore and pick the strike that suits the frame prep already in place.
19) Should I use a cylindrical lock like the Sargent 7G04 or go with a mortise lock for a storeroom?
Go cylindrical when the door is already bored for one and the traffic is ordinary. The 7G04 drops into the standard bore, needs no pocket cut in the door edge, and its internal through-bolts stiffen the assembly without more prep. A mortise lock is the answer when you need a deadbolt and latch in one case, heavier abuse resistance, or a lock case that accepts more function and trim variety, and it requires a routed pocket the door has to be prepped for. For a supply or utility room on a standard commercial door, the cylindrical is the practical choice.
20) Is there a heavier duty alternative to the Sargent 7G04 for a high traffic keyed opening?
The 7G04 is a standard duty Grade 2 cylindrical lock. For a heavier keyed cylindrical lever on the same door prep, the Dexter C1000 series runs Grade 1 with entry/office, classroom, classroom security and asylum functions available. The Corbin Russwin CL3100 series is Grade 1 and fire rated but in passage/closet function, which is non-keyed. The Arrow MK33 asylum lock is heavy duty with a conventional cylinder in the Schlage C keyway, which matters if the facility is standardized on Schlage C rather than a Sargent keyway.
21) What should I use on the closet doors that do not need to be keyed, to match the Sargent 7G04 on the storerooms?
The 7G04 is a keyed single cylinder lock, so on a closet that only needs a latch there is no reason to buy the cylinder. Non-keyed Grade 2 cylindrical passage/closet levers include the Accentra 5301LN Augusta, the Accentra 4601LN, the Falcon B101 medium duty passage, the Arrow GL01 with Sierra lever, and the Hager 2510 with Withnell lever. Grade 1 non-keyed options are the Falcon K101 and T101 and the Design Hardware X75. If the requirement is to keep the Sargent lever and rose on a closet door, the 7G04 can also be ordered LC, less cylinder.
22) Is a Baldwin 5103 or Emtek lever an alternative to the Sargent 7G04?
They are not interchangeable. The Baldwin Estate 5103 is offered as passage, privacy and handed half dummy trim, and the Emtek Arts and Crafts and Cortina leversets listed are dummy pairs - dummy trim has no latch at all and passage has no key. The 7G04 is a keyed storeroom lock rated Grade 2 for commercial use, and it is non-handed, where the Baldwin 5103 half dummy is ordered specifically as left hand or right hand. Use the Baldwin and Emtek trims for decorative interior doors and the 7G04 where the opening has to be secured with a key.
23) We do not want to issue keys for a storage room - what takes the place of a Sargent 7G04?
Code-operated levers remove the key from the equation. The Delaney LP250 is a Grade 2 electronic keypad leverlock, the Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function covering doors 1-1/8 inch to 2 inch, and Emtek offers a Classic keypad leverset. The 7G04 is a mechanical keyed lock taking a single cylinder, which is what lets it sit inside an existing Sargent master key system with keyed alike, keyed different or master keyed ordering. Pick the keypad route when access changes often and the key system route when the room has to answer to a building master.
24) What is the equivalent of the Sargent 7G04 for a restroom that needs privacy rather than a key?
A storeroom lock is the wrong function for a restroom because it locks from the outside with a key rather than from the inside by the occupant. Grade 2 privacy cylindrical options include the Hager 2540 with Withnell lever on doors 1-3/8 inch to 2 inch and the Kwikset 300BRNL Breton privacy lever at Grade 3 on 1-3/8 inch to 1-3/4 inch doors. Arrow also lists an MK02-TA privacy lock with a Tudor knob, non-keyed and fire rated, if a knob is acceptable. The 7G04 stays on the storage and mechanical rooms.
25) Is the Sargent 7G04 approved for exterior doors?
Yes, within reason. The 7G04 is built for standard duty commercial interior and exterior use. It suits secondary exterior doors, service entries and outbuildings on a storeroom function. A main public entrance seeing constant cycles is beyond a Grade 2 standard duty lock, and there you want a Grade 1 heavy duty cylindrical such as the Falcon K Series or a Corbin Russwin CL3100 Series lock. If the door is exposed, take a finish that holds up outdoors rather than a clear coated brass.
26) Is the BEST 7KC or 9K dummy trim a way to match a Sargent 7G04 on an inactive leaf?
Dummy trim is the right part for an inactive leaf but it is not a lock. The BEST 7KC single dummy trim is Grade 2 medium duty and non-keyed, and the BEST 9K 1DT single dummy trim is Grade 1 heavy duty and non-keyed; the Accentra 455LN Augusta is a Grade 1 single dummy and the Callan Bentley is a Grade 2 dummy lever. None has a latch or a cylinder. The 7G04 is the keyed storeroom lock for the active leaf, and you would pair it with dummy trim on the inactive leaf so the levers read the same across the pair.
27) I need a black or white finish on a commercial storeroom lever - which options carry one?
The Sargent 7G04 is offered in BSP black suede powder coat and WSP white suede powder coat alongside satin chrome 26D, satin nickel 15, oil rubbed bronze 10B and the brass and bronze finishes, on the same Grade 2 storeroom lock. Among the comparable commercial levers, the Hager 2580 storeroom is listed in 26D and the Cal-Royal AG05 storeroom in 26D. If the design calls for a painted black or white lever on a keyed storeroom door rather than a plated one, the 7G04 covers it without changing function or grade.
