Hager 3710 US26D – Frequently Asked Questions

1) Will the Hager 3710 interconnected lock fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The 3710 covers a 1-3/8 to 1-3/4 inch door thickness range as standard, so it works on older interior wood doors and on standard commercial 1-3/4 inch doors without a special order. It's cut for a 2-3/4 inch backset with a 4 inch center-to-center between the lever bore and the deadbolt bore, so the door prep has to match that spacing, not just the thickness.
2) What is an interconnected lock and why would I use one instead of a separate lever and deadbolt?
An interconnected lock puts the lever latch and the deadbolt on one chassis with a 4 inch center-to-center spacing, so retracting the inside lever pulls both bolts at once. That single-motion egress is why these get specified in apartments and multi-tenant corridors, where a tenant should never have to throw two separate devices to get out. A separate lever plus a standalone deadbolt gives you the same security but two motions and two independent preps. The 3710 runs the Entry - Single Locking (F95) function: key outside, thumbturn inside.
3) Will the Hager 3710 key into my existing Schlage C master key system?
Yes. The 3710 ships with a 6-pin cylinder in the Schlage C keyway as standard, which is the most common commercial keyway in North America, so it can be keyed into an existing Schlage C system. Other keyways are available as an option if your facility is on something else.
4) Can I put the Hager 3710 on a fire rated apartment entry door?
The 3710 is UL/cUL listed for all functions up to 3 hour "A" label single doors, with a UL10C positive pressure rating. It also meets the ANSI A117.1 accessibility code, so the lever trim satisfies ADA operable-hardware requirements. Single doors only for that fire listing.
5) What do I have to specify when ordering a Hager 3710 interconnected lock?
Three things decide the part: finish, lever design, and keying. Finishes run 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. Lever designs offered on the series are Archer, August and Withnell. Keying defaults to 6-pin Schlage C. Backset is 2-3/4 inch standard with 2-3/8 inch available as an option, so call that out if your existing prep is the shorter backset.
6) What is the closest Grade 2 keyed entry cylindrical lever if the opening does not need an interconnected deadbolt?
The Falcon B511CP6D is a Grade 2 cylindrical lever lock with an entrance/office function, medium duty. It handles a keyed entry opening with a latchbolt only, where the Hager 3710 pairs its keyed entry with a deadbolt for a Cylinder x Thumbturn interconnected setup. Choose the B511CP6D when the door prep is a single bore and the deadbolt is not part of the spec.
7) Which lever lock keys to the same Schlage C keyway as the Hager 3710?
Two peers share that keyway. The Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway keyed different and a 2-3/8 inch backset, and the Arrow MK33-BD-CS is a Grade 2 asylum function ball knob lock with a conventional Schlage C keyway cylinder. The Hager 3710 uses 6 pin cylinders in Schlage C keyway, so all three can go on one key system without a cylinder swap.
8) What should be specified instead for a door thicker than 1-3/4 inches?
The Hager 3710 is set up for a 1-3/8 inch to 1-3/4 inch door. For thicker leaves, the Corbin Russwin CL3110 passage lever covers 1-3/4 inch to 2 inch, and the Dexter C1000 asylum function lock covers 1-3/8 inch to 2 inch, both Grade 1. Note that neither is a keyed entry with a deadbolt, so confirm the function needed at the opening before substituting on thickness alone.
9) Which Grade 1 lever should be considered for a higher-cycle opening?
The Dexter C1000 entry/office lever is Grade 1 with a clutching keyed mechanism for 1-3/8 inch to 1-3/4 inch doors, and the Falcon K101 is a Grade 1 heavy duty passage lock, fire rated, spanning 1-3/8 inch to 2-1/4 inch. The Hager 3710 is Grade 2. On a high-traffic entrance where a clutching keyed lever is wanted, the C1000 entry/office matches the keyed function most closely.
10) What replaces the Hager 3710 on a storeroom or classroom door instead of an entry door?
Function drives the choice. 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, and the Cal-Royal AG03 is a classroom lever with a 6-pin Schlage C keyway and 2-3/4 inch backset. The AG03 shares the 2-3/4 inch backset and Schlage C keyway with the Hager 3710, so a door already prepped for the 3710 accepts it without re-boring.
11) Is the Hager 3710 handed? Do I have to order left or right hand?
Non-handed. One part number covers both swings, so you don't specify handing on the order and you can stock a single lock across a building of mixed-swing doors. What you do specify is finish and lever design.
12) Is Grade 2 enough for an apartment building entry door, or should I be looking at Grade 1?
The 3710 is BHMA certified ANSI A156.2 Series 4000 Grade 2, rated for standard duty commercial and heavy duty residential. For unit entry doors in multi-family, corridors, and offices, that's the normal specification. If the opening is a high-traffic public entrance taking hundreds of cycles a day, step up to a Grade 1 cylindrical lock such as the Dexter C1000 Series entry/office lever or the Corbin Russwin CL3100 Series. Note those are single-function cylindrical locks, not interconnected, so you'd add a separate deadbolt.
13) What's a keyed entry alternative to the Hager 3710 if I don't need the deadbolt?
If the opening only needs a keyed lever, the Cal-Royal AG00 entrance lever is Grade 2 with a 6-pin Schlage C keyway on a 2-3/8 inch backset and a 1-3/8 to 1-3/4 inch door thickness range, so it keys into the same system. The Falcon B511CP6D is another Grade 2 entry/office cylindrical lever. Neither includes a deadbolt, so if the door needs one you're back to the 3710 or to adding a separate deadbolt with its own prep.
14) Is there a lighter duty entry lever for a residential-grade opening?
For an interior or light residential door, the Cal-Royal AUS00 is a Grade 3 entrance/office lever with a solid brass forged body covering 1-3/8 inch to 1-3/4 inch doors, the same thickness range the Hager 3710 covers, and the Callan Artino is a Grade 3 entrance leverset. The Hager 3710 carries a Grade 2 commercial rating, so specify it where the opening is graded for commercial traffic and the lighter Grade 3 levers where it is not.
15) What is the difference between the Hager 3710 and a lever set with a separate deadbolt combo?
The Callan Bennett is a Grade 3 entrance leverset with a deadbolt combo, meaning the lever and the deadbolt are two separate units installed in two separate bores. The Hager 3710 is a Grade 2 keyed unit whose lever and deadbolt work as one Cylinder x Thumbturn assembly, so retracting both together is a single motion. Where the door is already prepped with two independent bores, the combo approach fits the existing prep.
16) Do the Baldwin Estate 5103 or Emtek dummy levers work as a replacement for a keyed entry lock?
No. The Baldwin Estate 5103 is offered in passage, privacy, and half dummy versions, and the Emtek Arts and Crafts and Cortina leversets are dummy pairs. None of those are keyed. The Hager 3710 is a keyed lock with a cylinder, so a dummy or passage lever only suits a door that is not meant to lock, such as an inactive leaf or a closet.
17) What is the alternative if the tenants should not carry a key at all?
For keyless access on the same class of opening, the Lockey 2835 is a mechanical pushbutton keyless lever lock with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, and the Delaney LP250 is a Grade 2 electronic keypad leverlock. The Hager 3710 is a keyed unit using Schlage C cylinders, so moving to a keypad removes key management but also removes the ability to put the door on an existing Schlage C master system.
18) Can a Yale or Accentra lever be brought onto a Schlage C key system alongside the Hager 3710?
The Accentra 107S is a Schlage cylinder adapter kit for Yale hardware, which is what lets Yale-prepped trim take a Schlage cylinder. The Hager 3710 already runs 6 pin Schlage C cylinders, so on a facility standardizing to one keyway the 3710 needs no adapter while the Yale trim does.
19) Is a Kwikset Breton or Delta lever an equivalent to the Hager 3710?
No. The Kwikset 200BRNL Breton is a Grade 3 passage lever for 1-3/8 inch to 1-3/4 inch doors and the 300BRNL Breton is Grade 3 privacy. They cover the same door thickness as the Hager 3710 but are non-keyed at a lighter grade, while the 3710 is Grade 2 and keyed. On a unit entry door the Breton pair is a bed/bath and hall solution, not the entry lock.
20) Will the Hager 3710 hold up in a coastal or humid building?
The chassis is heavy gauge steel with a zinc dichromate coating for corrosion resistance, and the exposed trim is wrought brass, bronze, or stainless steel depending on finish. For a wet or salt-air opening, the stainless-family finishes (626 satin chrome, 625 bright chrome) hold up better than a bright brass. The deadbolt itself is brass with a concealed hardened steel roller to resist sawing.
21) I need to match existing hardware in the building. What finish is the Hager 3710 available in?
Five finishes: 605 bright brass, 606 satin brass, 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. 626 satin chrome is the usual commercial default and the easiest to match against existing closers, hinges and exit devices; 613 is the one to pick when the building is on an oil-rubbed bronze standard. All five are offered with the Withnell lever.
22) Which lever works for the non-locking doors in the same building as the Hager 3710 entries?
For corridor, hall, and closet doors, the Falcon B101 is a Grade 2 non-handed cylindrical passage lever and the Accentra 5301LN Augusta is a Grade 2 cylindrical lever in passage/closet function. Both sit at the same Grade 2 rating as the Hager 3710, which keeps the whole floor on one performance grade while only the entries carry the keyed cylinder and deadbolt.
