Hager 3570 WTN US26D – Frequently Asked Questions

1) How does classroom function work on the Hager 3570 lever lock?
Classroom function (F84) means the outside lever is locked and unlocked by key only. Turn the key to lock the outside lever and the door stays secure from the corridor while the inside lever always retracts the latch for free egress. There is no inside button or thumbturn, so a teacher cannot lock the door from inside the room with this function. If staff need to lock down from inside the classroom, look at a classroom security lock with two cylinders instead, such as the Dexter C1000 Classroom Security lever.
2) Is the Hager 3570 handed, or does one lock work on both left and right doors?
Non-handed. One 3570 cylindrical lever lock works on a left or right hand door, which is why a school or property manager can stock a single part number for a whole building rather than pairing handing to each opening.
3) What backset does the Hager 3570 classroom lock use, and can it go into an existing 2-3/8 inch bore?
Standard configuration is a 2-3/4 inch backset, which is the usual commercial prep. The 3570 is also offered in 2-3/8 inch, 3-3/4 inch and 5 inch backsets, so a door already bored at 2-3/8 inch can be served by specifying that backset rather than re-prepping the door.
4) Will the Hager 3570 latch into the strike already in my frame?
It is supplied for an ASA strike, 1-1/4 x 4-7/8 inches, with a 1/2 inch throw deadlocking stainless latchbolt. If your frame already has the standard 4-7/8 inch ASA lip prep, the 3570 drops in. A frame cut for a small T-strike or a 2-3/4 inch faceplate will need the opening enlarged or a filler plate.
5) Can the Hager 3570 be keyed into our existing Schlage C master key system?
Yes. The 3570 ships with a Schlage C keyway as standard on the single cylinder, so it keys alike or masters into an existing Schlage C system. Other keyways are available on request. If you run small format interchangeable cores, order the SFIC prep version, which comes less core so your locksmith installs your own cores.
6) Can the Hager 3570 go on a fire rated classroom door?
Yes. All functions are UL and cUL listed up to 3 hours on an A label single door, with UL10C positive pressure rating. One install caution: the thru-posts and screws must be fitted, since omitting them voids the UL rating and BHMA certification.
7) Which classroom lever lock should I use on a door thicker than 1-3/4 inches?
The Hager 3570 accommodates doors from 1-3/8 inch to 2 inch. The Dexter C1000 classroom lever is listed for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal AG05 storeroom lever is also 1-3/8 inch to 1-3/4 inch, so for a 2 inch leaf the Hager range covers it where those two stop.
8) What do I have to specify when ordering a Hager 3570?
Three choices: lever design (Archer, August or Withnell), finish, and cylinder type (standard cylinder or SFIC prep less core). Finishes offered are 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome and 626 satin chrome. Lead lining is an available option for radiology and imaging doors.
9) Does the Hager 3570 lever meet ADA requirements for accessible openings?
The 3570 uses a lever handle and meets ANSI A117.1 accessibility code, so it satisfies the no-tight-grasping requirement for accessible doors. Rose diameter is 3-11/32 inches and there are no exposed mounting screws on the trim.
10) What other brands offer a classroom lever lock like the Hager 3570?
Two close alternatives: the Cal-Royal AG03 classroom lever, which also uses a 6-pin Schlage C keyway and a 2-3/4 inch backset, and the Dexter C1000 classroom lever, which has a clutching lever and fits 1-3/8 to 1-3/4 inch doors. The Hager 3570 is the one to pick if you need door thickness coverage out to 2 inch, since the Dexter stops at 1-3/4 inch.
11) If the door does not need to be keyed, what takes the place of the Hager 3570?
The 3570 is a keyed lever lock. For an unkeyed opening on the same cylindrical prep, the Falcon B101 is a Grade 2 medium-duty non-handed cylindrical passage lever and the Falcon K101 is a Grade 1 heavy-duty passage lever with non-handed levers listed for 1-3/8 inch to 2-1/4 inch doors. Accentra 4601LN is a Grade 2 passage cylindrical lever in the 4600 Series.
12) What is the difference between the Hager 3570 and an institutional or asylum function lever?
The Hager 3570 is a classroom lock keyed on the outside with a single cylinder. An asylum or institution function lock is keyed on both sides: the Dexter C1000 asylum (F87) is Grade 1 for doors 1-3/8 inch to 2 inch, and the Arrow MK33-BD-CS is a Grade 2 asylum lock with a Schlage C conventional cylinder. Use those where both faces must be keyed.
13) Can I use a residential-grade lever instead of the Hager 3570 on a commercial classroom door?
The Hager 3570 is a commercial cylindrical lock. Grade 3 levers such as the Cal-Royal AUS00 entrance/office lever or the Kwikset 200BRNL Breton passage lever are lighter-duty options for doors 1-3/8 inch to 1-3/4 inch thick, and neither is a classroom function. For a commercial classroom opening the 3570 is the right tier.
14) I need keyless entry on a classroom door instead of a keyed lever - what are my options?
The Hager 3570 is keyed with a Schlage C cylinder. For pushbutton access, the Delaney LP250 is a Grade 2 electronic keypad leverlock, and the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function for doors 1-3/16 inch to 2 inch. Keypad units are not classroom function, so verify the door schedule.
15) What classroom-door alternative should I look at if the opening needs vandal resistance or electrified control?
The Hager 3570 is a mechanical cylindrical lock. For heavier or electrified duty, the Corbin Russwin CL3110 is a Grade 1 vandal resistant cylindrical lever with passage function and a fire rating for 1-3/4 inch to 2 inch doors, and the CL33903 is a Grade 1 fail safe electrified cylindrical lever at 12VAC/DC for the same door range.
16) I need matching passage and privacy levers for the rooms that do not get keyed. What pairs with a classroom lock like this?
A classroom lock only covers keyed openings. For hall, closet and non-keyed doors alongside it, cylindrical passage levers such as the Falcon B101 or the Accentra 5301LN Augusta cover the same style of opening, and the Corbin Russwin CL3110 is a vandal resistant passage option for 1-3/4 to 2 inch doors. Bathroom and bedroom doors need a privacy function instead, such as the Baldwin Estate 5103 privacy lever.
17) How durable is the Hager 3570 chassis for a busy school corridor?
The chassis is heavy gauge steel with a zinc dichromate coating for corrosion resistance, and the latchbolt is stainless steel. Exposed trim is wrought brass, bronze or stainless steel depending on finish. It is rated for standard duty commercial use, so for extremely high traffic entries a heavy duty Grade 1 chassis such as the Falcon K101 or T Series is the step up.
18) Does a dummy lever work as a substitute for the Hager 3570 on the inactive leaf of a pair?
No - a dummy has no latch. The Hager 3570 is a cylindrical latching lock with an ASA strike. For a pull-only inactive leaf, use a dummy trim such as the BEST 9K Series 1DT Grade 1 heavy-duty single dummy, the BEST 7KC Series 1DT Grade 2 medium-duty single dummy, or the Accentra 455LN Augusta Grade 1 single dummy in the 5400 Series.
