Sargent 2870-10G04 LL 26D – Frequently Asked Questions

1) What does the storeroom function on the Sargent 2870-10G04 actually do at the door?
Storeroom/closet function: the outside lever is always locked and the key retracts the latch for entry only, with no way to leave it unlocked from the outside. The inside lever always retracts the latch for free egress. That is the function you want on mechanical rooms, IT closets, stock rooms and any door that must never be left on a button. If you need staff to be able to secure the door from inside the classroom, that is a different function.
2) What backset does the Sargent 10 Line 2870-10G04 come in, and will it drop into an existing 2-3/4 inch prep?
Backsets offered are 2-3/8, 2-3/4, 3-3/4 and 5 inches, so a standard 2-3/4 inch commercial prep is covered directly. The 3-3/4 and 5 inch backsets are there for wide-stile and older institutional preps where the bore sits further off the edge, which is usually what saves you from re-drilling a door on a retrofit.
3) Can the Sargent 2870-10G04 go on a fire rated door?
It's UL listed for 3-hour fire doors and meets ANSI/UL 10C positive pressure fire test requirements, and it also carries a windstorm listing. Storeroom function suits fire door use because the outside lever stays locked and the inside lever always releases.
4) Does the Sargent 2870-10G04 come with a cylinder, or do I supply my own core?
It's supplied with interchangeable core prep, not a finished keyed cylinder, so you drop in the core your facility already uses. It works with most facility key systems including Sargent, and it accepts Schlage and Medeco LFIC cylinders. If your building is standardized on one of those, you order the lock and key it into your existing system rather than starting a new one.
5) What is the closest Grade 1 storeroom cylindrical lever lock to the Sargent 2870-10G04 if I need a different brand on the same opening?
The Sargent 2870-10G04 is a Grade 1 storeroom/closet cylindrical lever lock. Among other Grade 1 cylindrical lever locks, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever lock for 1-3/4 inch to 2 inch doors, but it is passage/closet function, so it does not lock. For a keyed storeroom function the Cal-Royal AG05 is a storeroom lever lockset with a deadlocking latchbolt, though it is Grade 2 and fits 1-3/8 inch to 1-3/4 inch doors. Match the function first: a storeroom opening needs a lever that stays locked outside while the inside lever always retracts the latch, which passage and dummy trims cannot do.
6) Can I use a Grade 2 storeroom lever instead of the Sargent 10 Line on a lower-traffic door?
Yes, on doors that do not need Grade 1. The Hager 2580 is a Grade 2 storeroom cylindrical lock with the Withnell lever covering 1-3/8 inch to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever lockset with a deadlocking latchbolt for 1-3/8 inch to 1-3/4 inch doors. The Sargent 2870-10G04 is Grade 1 and heavy duty, tested to 9.6 million cycles with UL listing for 3-hour fire doors. On stairwells, mechanical rooms, and other high-cycle or fire-rated openings, stay with the Grade 1; on a back-office supply closet the Grade 2 storeroom function behaves the same way at the door.
7) I need a keyed lever that lets staff leave it unlocked during the day - what takes the place of the Sargent 2870-10G04?
That is entry/office function, not storeroom. The Dexter C1000 entry/office cylindrical lever lock is Grade 1, clutching and keyed, for 1-3/8 inch to 1-3/4 inch doors. The Falcon B511CP6D is a Grade 2 medium duty cylindrical lever with entry/office function, and the Hager 2525 is a Grade 2 commercial cylindrical entry lock for 1-3/8 inch to 2 inch doors. Entry/office lets the outside lever be left unlocked; the Sargent 2870-10G04 storeroom function does not, which is exactly why it is chosen for supply and equipment rooms.
8) I need the door to unlock from an access control system - what do I order instead of the Sargent 2870-10G04?
The Sargent 2870-10G04 is a mechanical cylindrical lock with no electrical connection. For an electrified cylindrical lever, the Corbin Russwin CL33903 is a Grade 1 fail safe lever at 12VAC/DC for 1-3/4 inch to 2 inch doors, available with an NZ lever and D rose or in a keyed configuration. Fail safe means the lever unlocks when power drops, so confirm your fire and egress strategy calls for fail safe rather than fail secure before ordering.
9) Do I need to specify handing when ordering the Sargent 10 Line lever lock?
No handing to specify. The 2870-10G04 is non-handed, so one part number covers left and right hand doors. That is what you want when you are stocking spares for a building instead of matching a specific opening.
10) Is a Grade 1 cylindrical lock worth it over a Grade 2 storeroom lever for a high traffic door?
On a door getting constant use, yes. The Sargent 10 Line is ANSI/BHMA Grade 1 and tested to 9.6 million cycles, nine times the Grade 1 cycle requirement, with 1.5 times the required torque resistance and a steel cylindrical housing with a stainless latch. A Grade 2 storeroom lever such as the Hager 2580 or the Cal-Royal AG05 is the lighter-duty route for interior closets and lower-traffic openings where the cycle count and lever-torque abuse just aren't there.
11) What lever, rose and finish does the Sargent 2870-10G04 come in?
One configuration: the L lever on the L rose, which is 3-1/8 inches, in 26D satin chromium plated over nickel. 26D is the standard commercial finish, so it matches most existing office, school and healthcare hardware without a special order. All 10 Line lever designs conform to ADA requirements for barrier-free operation.
12) I need a Grade 1 lever on the same door but not keyed. What pairs with the Sargent storeroom lock?
For unkeyed openings on the same run of doors, Grade 1 cylindrical passage levers include the Falcon K101, which covers 1-3/8 to 2-1/4 inch doors and is fire rated, the Corbin Russwin CL3110 vandal-resistant passage lock for 1-3/4 to 2 inch doors, and the Falcon T101 heavy duty passage lever. For a dummy trim on an inactive leaf, the BEST 9K Series 1DT is the Grade 1 option. Keep the storeroom Sargent on the doors that must stay locked and use passage function where free access is fine.
13) Is there a Grade 1 cylindrical storeroom alternative if the Sargent 10 Line won't fit my door?
If the opening is under the 4-1/2 inch stile the 10 Line needs, or you want a different key platform, the Dexter C1000 Series is the Grade 1 cylindrical line to look at, covering 1-3/8 to 2 inch doors in asylum function and 1-3/8 to 1-3/4 inch in classroom, classroom security and entry/office. For a lighter duty storeroom lever, the Hager 2580 is Grade 2 and takes 1-3/8 to 2 inch doors, and the Cal-Royal AG05 is a Grade 2 storeroom lever with a deadlocking latchbolt for 1-3/8 to 1-3/4 inch doors.
14) Is a passage lever the same thing as the Sargent 2870-10G04 storeroom lock?
No. Passage levers have no cylinder and never lock. The Falcon K101 is a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, for 1-3/8 inch to 2-1/4 inch doors, and the Design Hardware X75 is a Grade 1 passage lever lockset for 1-3/4 inch doors - both share the Grade 1 rating with the Sargent 2870-10G04 but neither accepts a key. The Sargent is keyed with a single cylinder. Buyers standardizing a corridor often pair the two: passage on the non-secured doors, storeroom on the ones that must stay locked.
15) The Sargent 2870-10G04 takes an interchangeable core - what alternatives work with an interchangeable core key system?
The Sargent 2870-10G04 is supplied with LFIC prep and accepts Schlage and Medeco LFIC cylinders alongside Sargent key systems. Within the interchangeable core family, the BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim in the same 9K line used for IC keying, and the BEST 7KC Series 1DT is the Grade 2 medium duty equivalent - both are non-keyed dummy trim, so they mount as the pull side of a pair rather than as a lock. If the existing hardware is Yale and the key system is Schlage, the Accentra 107S is a Schlage cylinder adapter kit for Yale hardware.
16) What matches the Sargent 2870-10G04 on the inactive leaf of a pair or a false door?
Dummy trim, which mounts a lever with no latch behind it. The BEST 9K Series 1DT is a Grade 1 heavy duty single dummy trim cylindrical lever, keeping the same Grade 1 rating as the Sargent 2870-10G04 lock on the active leaf. The Accentra 455LN Augusta from the 5400 Series is a Grade 1 heavy duty single dummy cylindrical lever, and the Callan Bentley is a Grade 2 dummy lever. Dummy trim carries no cylinder and no latch, so it cannot secure an opening on its own.
17) What is the difference between the Sargent 2870-10G04 and an asylum or institutional function lever?
The storeroom function on the Sargent 2870-10G04 keys the outside and leaves the inside lever always free to exit. Asylum function keys both sides, so there is no free egress from within. The Dexter C1000 asylum (F87) is a Grade 1 cylindrical lock for 1-3/8 inch to 2 inch doors, and the Arrow MK33-BD-CS is a Grade 2 heavy duty asylum/institution/utility lock with a ball knob and a conventional cylinder in the Schlage C keyway. Confirm your egress requirements before specifying a both-sides-keyed function on an occupied space.
18) Which lever locks cover a thicker door than the Sargent 2870-10G04?
The Sargent 2870-10G04 covers 1-3/8 inch to 2 inch doors with a minimum 4-1/2 inch stile. The Falcon K101 goes to 1-3/8 inch to 2-1/4 inch, though it is a passage function with no cylinder. Among keyed options at the same range, the Hager 2580 Grade 2 storeroom lock covers 1-3/8 inch to 2 inch. Measure the leaf before ordering: a 1-3/8 inch door takes adapter plates on the Sargent, and the Dexter C1000 classroom and entry/office versions stop at 1-3/4 inch.
19) Can I put a residential-grade lever on the same doors as the Sargent 2870-10G04?
The Sargent 2870-10G04 is a commercial Grade 1 heavy duty lock. The Kwikset 200BRNL Breton passage lever and 300BRNL Breton privacy lever are Grade 3 for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AUS00 entrance/office lever is Grade 3 with a solid brass forged body for the same thickness range. Those suit apartment interiors and light-traffic residential openings; commercial corridors, stairwells, and fire-rated doors are where the Grade 1 rating and the 9.6 million cycle durability of the Sargent earn their place.
20) What replaces a keyed lever like the Sargent 2870-10G04 when I do not want to issue keys at all?
Keypad levers remove the key from the equation. The Lockey 1150 is a heavy duty mechanical keypad lever set with double combination in passage function for 1-1/8 inch to 2 inch doors, requiring no power or wiring. The Delaney LP250 is a Grade 2 electronic keypad leverlock. The Sargent 2870-10G04 is a keyed single cylinder lock with LFIC prep, so it stays on the facility key system and rekeys by swapping cores - the deciding question is whether you want the opening tied to your master key hierarchy or managed by codes.
21) Is a privacy lever an acceptable substitute for the Sargent 2870-10G04 on a restroom or single-occupancy door?
Only if the door does not need to be keyed. The Arrow MK02-TA is a privacy cylindrical lock with a tudor knob, non-keyed, fire rated, for 1-3/4 inch to 2 inch doors, and the Hager 2540 is a Grade 2 privacy cylindrical lock with the Withnell lever for 1-3/8 inch to 2 inch doors. Privacy function locks from inside with a thumbturn and releases with an emergency tool, with no cylinder for staff keys. The Sargent 2870-10G04 is keyed storeroom, so it keeps the door secured against everyone without a key rather than against whoever is currently inside.
22) Does the Sargent 2870-10G04 need to be handed like some lever locks?
No. The Sargent 2870-10G04 is non-handed, so one part number serves left and right hand openings and there is no hand to specify when ordering. The Falcon K101 and B101 are likewise non-handed cylindrical levers. By contrast, the Baldwin Estate 5103 half dummy is sold as separate left hand and right hand parts, so the hand has to be determined at the door before the order goes in. On a fleet of doors the non-handed lock keeps the stockroom to one SKU.
23) What is the Sargent 2870-10G04 built out of, and will it hold up in a school or hospital corridor?
Wrought brass and bronze roses over a steel cylindrical housing, with a stainless steel latch. That construction plus the 9.6 million cycle rating is why the 10 Line ends up on education, healthcare, government and manufacturing corridors where a lever gets pulled on hard all day. It is a commercial-duty lock, not a residential one.
24) What door prep standard does the Sargent 10 Line lever lock follow?
Door and frame prep follows ANSI/BHMA A156.115, and Sargent supplies templates for marking the mounting holes. Prep varies with which backset you order, so pick the backset first and drill to that template, not to a generic one.
