Hager 3579 US26 – Frequently Asked Questions

1) What does a keyed communicating function lock like the Hager 3579 actually do, and where would I use one?
Keyed communicating (F113) is the function for a door between two spaces that each need their own control, most often a pair of connecting hotel or patient rooms. The Hager 3579 3500 Series is the keyed communicating version with a blank plate on one side, so the door is operated and keyed from one side and the other side carries a plate instead of a lever. If you want a door both sides can always open freely, that's a passage lockset, not this one.
2) Will the Hager 3579 cylindrical lock fit a 1-3/4 inch commercial door?
Yes, 1-3/4 inches is the stated door thickness for the 3579 and it's the standard commercial door thickness, so a typical hollow metal or solid core opening takes it without any special prep.
3) What backset does the Hager 3579 use and will it hit my existing strike prep?
The 3579 uses a 2-3/4 inch backset, which is the usual commercial bore spacing, and it ships with a 1-1/4 x 4-7/8 inch ASA strike. If the frame already has ASA (T-strike) prep, the strike drops straight in. A frame cut for a smaller square-corner residential strike needs to be modified or a filler plate used.
4) Is the Hager 3579 lock fire rated for a 3-hour opening?
Fire rated, and UL/cUL listed to 3 hours. One condition matters on the install: the thru-posts and screws must be fitted. Leaving them out voids the BHMA certification and the UL rating on the 3579.
5) Does the Hager 3579 meet ADA and what ANSI grade is it?
BHMA certified to ANSI A156.2, Series 4000, Grade 2, and ADA compliant per ANSI A117.1. Grade 2 is the standard-duty commercial tier, which suits offices, retail and multi-tenant residential. For a high-abuse opening like a school corridor, a Grade 1 cylindrical lock such as the Dexter C1000 Series or the Corbin Russwin CL3100 Series is the heavier option.
6) What keyway does the Hager 3579 come in, and can I get it less core for my own small format cores?
Schlage C is the standard keyway on the 3579, with other keyways available, so it can be keyed into most existing Schlage C master systems. It's also offered SFIC prep less core, which is the one to order if you run your own interchangeable core system and want to stamp your own cores in. Standard cylinder is the choice if you want it keyed conventionally.
7) What is the closest Grade 2 cylindrical lever equivalent to the Hager 3579 if I need a keyed function on a commercial opening?
The Hager 3579 is a Grade 2 cylindrical lock in the keyed communicating function, BHMA certified to ANSI A156.2 Series 4000. The closest Grade 2 keyed cylindrical lever alternatives are the Cal-Royal AG05, a Grade 2 storeroom lever lockset with a deadlocking latchbolt, and the Falcon B511CP6D, a Grade 2 medium duty cylindrical lever in entry/office function. Both are keyed cylindrical levers at the same grade, but they perform storeroom and entry/office duty respectively rather than communicating, so confirm which function the opening calls for before swapping.
8) I need the same lever style on a door that does not need to lock at all - what do I use instead of a keyed communicating lock?
For an opening that only needs the door to latch, a passage lever is the right part rather than the keyed communicating Hager 3579. Grade 2 passage options include the Falcon B101, a medium duty non-handed cylindrical passage lever, the Arrow GL01 with the Sierra lever for doors 1-3/4 inch to 2 inch thick, and the Accentra 5301LN Augusta from the 5300 Series in passage/closet function. All three latch without any keyed operation.
9) My spec calls for Grade 1 on this opening - what cylindrical lever meets that instead of the Hager 3579?
The Hager 3579 is certified Grade 2 to ANSI A156.2, so a Grade 1 specification needs a different lock. Grade 1 cylindrical levers include the Corbin Russwin CL3110 from the CL3100 Series, a vandal resistant fire rated passage/closet lever for 1-3/4 inch to 2 inch doors; the Falcon K101, a Grade 1 heavy duty fire rated passage lever for doors 1-3/8 inch to 2-1/4 inch; and the Dexter C1000 Series in keyed functions such as classroom, classroom security, entry/office and asylum. Match the function your drawing calls for, since these Grade 1 units cover passage and keyed duties rather than communicating.
10) The opening is a patient room or holding room that needs to be secured from the corridor side - is the Hager 3579 the right lock?
The Hager 3579 is a keyed communicating lock, which is a different function from asylum or institutional locks. For institutional openings the Dexter C1000 Series asylum lock in F87 function and the Arrow MK33-BD-CS Grade 2 heavy duty asylum lock with a conventional cylinder in Schlage C keyway are the purpose-built choices. The Arrow MK33 uses a ball knob rather than a lever, so confirm ADA lever requirements for the space before choosing it.
11) I want to keep the Schlage C keyway across the building - what else keys into the same system as the Hager 3579?
The Hager 3579 is a keyed communicating cylindrical lock available with SFIC prep less core as well as a standard cylinder. Peers that carry a Schlage C keyway include the Cal-Royal AG00 entrance lever with a 6-pin Schlage C keyway keyed different on a 2-3/8 inch backset, the Cal-Royal AG03 classroom lever with the same 6-pin Schlage C keyway on a 2-3/4 inch backset, and the Arrow MK33-BD-CS with a conventional Schlage C cylinder. The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, which lets Yale openings take a Schlage cylinder rather than serving as a lock itself.
12) The door on my job is 1-3/4 inch thick but I have a few at 1-3/8 inch - which locks cover both?
The Hager 3579 is built for doors 1-3/8 inch through 2 inch, so it covers both thicknesses in one part number. Peers with the same breadth include the Dexter C1000 Series asylum lock at 1-3/8 inch to 2 inch, the Falcon K101 at 1-3/8 inch to 2-1/4 inch, and the Deltana 6201 Manchester, 6411 Morant and 6431 Linstead entry levers at 1-3/8 inch to 2 inch. Locks such as the Arrow GL01 and Corbin Russwin CL3110 start at 1-3/4 inch, so they will not cover the thinner doors.
13) The Hager 3579 is fire rated - which comparable locks carry a fire rating for a labeled door?
The Hager 3579 is fire rated and UL/cUL listed for a 3-hour rating. Among the peers, the Falcon K101 Grade 1 heavy duty passage lever, the Corbin Russwin CL3110 Grade 1 vandal resistant passage lever and the Arrow MK02-TA privacy lock with Tudor knob are also fire rated. Verify the specific label hourly rating against the door assembly before ordering.
14) What finishes and lever styles can I get the Hager 3579 3500 Series lock in?
Five finishes are orderable: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 626 satin chrome and 630 satin stainless steel, each available with either the standard cylinder or SFIC prep. The lever supplied is the Withnell design. Exposed trim is wrought brass, bronze or stainless steel depending on finish, with the lever zinc based and plated to match the BHMA symbol.
15) How much of the door face does the Hager 3579 rose cover, and will it hide my old lock's marks?
Rose diameter on the 3579 is 3-11/32 inches (85mm), so it covers a standard 2-1/8 inch cross bore with room to spare. Wear rings or paint shadow outside that circle will still show. There are no exposed mounting screws on the trim, so the face stays clean.
16) Does the Hager 3579 latch stay locked if someone tries to shim the door?
The latchbolt is stainless steel with a 1/2 inch (13mm) throw and it is deadlocking, so the anti-friction plunger keeps the bolt from being pushed back with a card or shim once the door is shut. The 1/2 inch throw is the normal cylindrical lock projection, so it needs a properly aligned strike lip to hold reliably; a badly gapped frame is what causes latch failures, not the bolt.
17) Is there a version of the Hager 3500 Series lock for a healthcare or clean environment?
An anti-microbial coating option is offered in US26D satin chrome on the 3500 Series, which is the one specified for patient rooms, labs and food service areas. Lead lining is also available as an option, which matters for imaging suite doors.
18) I need a lever lock for the same building but a passage door, not a communicating door. What pairs with the Hager 3579?
The 3579 is keyed communicating only, so hall, closet and other free-swinging doors need a passage function lockset. Comparable Grade 2 passage levers include the Falcon B101 in the B Series, the Accentra 5301LN Augusta in the 5300 Series, and the Design Hardware J75. For a Grade 1 passage lever in the same openings, the Corbin Russwin CL3110 is fire rated and fits 1-3/4 to 2 inch doors.
19) Is the Hager 3579 approved for high wind or hurricane zone work?
The 3500 Series lock carries Miami Dade County approval, which is what a Florida HVHZ job typically asks for on an opening's hardware. It's also UL/cUL listed for 3 hours and BHMA Grade 2 certified, so it covers the usual spec lines together.
20) Is a dummy lever a substitute for the Hager 3579 on the second leaf of a pair of doors?
No. A dummy lever is fixed trim with no latch, so it cannot secure or latch a door the way the Hager 3579 keyed communicating cylindrical lock does. Dummy trim such as the BEST 9K Series 1DT single dummy, the BEST 7KC Series 1DT single dummy, the Callan Bentley Grade 2 dummy lever or the Baldwin Estate 5103 half dummy in left or right hand is the right choice only where the leaf is held by flush bolts or similar and needs a pull only.
21) Can I use a Grade 3 residential lever where the Hager 3579 is specified?
The Hager 3579 is a commercial Grade 2 lock certified to ANSI A156.2. Grade 3 levers such as the Cal-Royal AUS00 entrance/office lever with a solid brass forged body for 1-3/8 inch to 1-3/4 inch doors, the Callan Artino entrance leverset, the Callan Asheville passage leverset and the Kwikset 200BRNL Breton passage lever for 1-3/8 inch to 1-3/4 inch doors sit a grade below and are built for lighter interior and residential duty. If the facility standard or drawing states Grade 2, a Grade 3 lever will not meet it.
22) What should I use instead of the Hager 3579 if I want keyless code entry on the door?
The Hager 3579 operates with a cylinder and key. For code entry without keys, the Lockey 1150 heavy duty mechanical keypad lever set with double combination in passage function fits doors 1-1/8 inch to 2 inch thick, and the Lockey 2835DC double combination mechanical keyless lever lock fits doors 1-3/16 inch to 2 inch. The Lockey 2835 single combination version is ADA compliant. Electronic options include the Delaney LP250 Grade 2 electronic keypad leverlock and the Emtek Classic keypad leverset.
23) The opening needs access control tied into the building system - what replaces a mechanical communicating lock?
The Hager 3579 is a mechanical keyed lock with no electrical provision. Where the opening has to release from an access control system, the Corbin Russwin CL33903 Grade 1 fail safe electrified cylindrical lever operates on 12VAC/DC and fits doors 1-3/4 inch to 2 inch, offered with the NZ lever and D rose and in a keyed 12VAC/DC version. Fail safe means the lock unlocks on loss of power, so confirm that behavior suits the opening's egress and security requirements.
24) A bathroom or bedroom door needs to lock from inside only - is the Hager 3579 the right function?
No. The Hager 3579 is a keyed communicating lock, which is not a privacy function. For inside-only locking use a privacy lock: the Arrow MK02-TA is a Grade 2 privacy lock with a Tudor knob, fire rated, for doors 1-3/4 inch to 2 inch; the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors; and the Baldwin Estate 5103 privacy lever with the 5048 rose is a decorative option. The Arrow uses a knob rather than a lever, which matters where ADA lever operation is required.
25) I am standardizing lever trim across a floor - which passage levers match a commercial Grade 2 standard rather than a decorative one?
The Hager 3579 is a commercial Grade 2 lock offered with Archer, August and Withnell lever designs. If the rest of the floor needs matching passage function at a commercial grade, the Design Hardware J75 flat lever passage lockset from the J Series is Grade 2 for 1-3/4 inch doors and the Design Hardware X75 from the X Series is the Grade 1 flat lever equivalent. Decorative passage leversets such as the Bravura Atlanta, Orlando and Tampa or the Baldwin Estate 5103 passage lever are Grade 2 or residential trim styles intended for a different look.
26) Is the Hager 3579 chassis suitable for a damp or coastal opening?
The chassis is heavy gauge steel with a zinc dichromate coating for corrosion resistance, and the latchbolt is stainless steel. For an exposed exterior opening, ordering it in 630 satin stainless keeps the visible trim in stainless as well.
