Dormakaba J3-10-LG-626 – Frequently Asked Questions

1) Will the Dormakaba J300 interconnected lockset fit my existing door prep with 5-1/2 inch hole centers?
Yes. The J300 fits doors bored with either 4 inch or 5-1/2 inch hole centers, which covers both of the common interconnected prep patterns on multifamily entry doors. Backset is ordered as either 2-3/8 or 2-3/4 inches, so match that to the existing cross-bore. Door thickness range is 1-3/8 to 1-3/4 inches, so it works on both standard commercial 1-3/4 inch doors and older 1-3/8 inch apartment doors.
2) Do I have to specify handing when ordering a Dormakaba J300 lockset?
Handing is a required selection on the J300, left hand/left hand reverse or right hand/right hand reverse, because the strike and latch orientation are shipped set. The lock body itself is non-handed for installation, with one exception: the LS lever is handed and has to match the door swing. If you are ordering the L118, LG, LC or LR lever, the lever will work either way.
3) What is an interconnected lock and do I need one for apartment entry doors?
An interconnected lockset ties the deadbolt to the lever so that turning the inside lever retracts both the latch and the deadbolt in one motion. That single-motion egress is what most codes require on apartment and condo entry doors, and it is the reason you use an interconnected set instead of a separate cylindrical lock plus deadbolt. The J300 is built for exactly that: light-duty commercial openings in apartments, condominiums, hotels, assisted living, and multifamily housing.
4) Is the Dormakaba J300 rated for a fire door?
A UL listed 3 hour fire rated version of the J300 is available as an option, so it is not standard on every configuration. If the opening is a rated apartment corridor door, specify the fire rated option when you order. The J300 also carries ANSI/BHMA A156.2 Grade 2 certification and meets A117.1 accessibility code and ADA requirements.
5) What is the closest Grade 2 interconnected lock to the Dormakaba J300 for an apartment entry door?
The Schlage CS210-B500 is the nearest peer. Both are ANSI/BHMA Grade 2 interconnected locksets with an entrance function, so both give single-motion egress on a multifamily unit door. The J300 is ANSI/BHMA A156.2 Grade 2 certified and built for light-duty commercial openings such as apartments, condominiums, and assisted living, while the CS210-B500 in the Schlage CS210 Series is rated heavy duty. If the opening sees heavy tenant traffic, the CS210-B500 is the heavier-duty route; for the light-duty multifamily door the J300 targets, the J300 covers the same function.
6) I need a keyed lever lock for a school classroom, not an apartment. Is the J300 the right lock?
No. The Dormakaba J300 is an entrance-style interconnected lockset intended for multifamily housing, hotels, and assisted living, where single motion egress is the requirement. For a classroom opening, the Schlage S270 is the lock to specify: it is a Grade 2 cylindrical keyed lever lock with a classroom function in the Schlage S200 Series, rated heavy duty. Classroom function and interconnected entry function are different lock behaviors, so the two are not interchangeable regardless of both carrying Grade 2.
7) Can a Schlage handleset be used in place of the Dormakaba J300 on a unit entry door?
They solve different openings. The Schlage Residential FC58 Plymouth is an outside handleset with entrance function in the Schlage Custom FCT-Series - a residential handleset with a grip, not a Grade 2 commercial interconnected lockset. The Dormakaba J300 is ANSI/BHMA A156.2 Grade 2 certified, meets A117.1 accessibility code and ADA requirements for barrier-free accessibility, and is available with an optional UL listed 3 hour fire rating. On a commercial multifamily corridor door where the spec calls for a certified grade and a fire rating, the J300 answers the spec and the handleset does not.
8) Should I order the J300 as single cylinder or double cylinder?
Single cylinder gives you a key outside and a thumbturn inside; double cylinder is keyed on both sides. Double cylinder is chosen where there is glass near the lock and you do not want someone reaching through to the turn, but many jurisdictions restrict key-both-sides on a required egress door, so check your local code before you commit to it. Both are offered on the J300 across every lever and both finishes.
9) Can I key all the Dormakaba J300 locks in my building alike?
Keying is a required choice on the J300 and both keyed different and keyed alike are available at no charge. For a building where maintenance carries one key to a group of units, order keyed alike within that group; unit entry doors normally go keyed different. Order the whole group in one go so the keying is set together rather than trying to match a later batch.
10) What is a good alternative to the Dormakaba J300 if I need a heavy duty interconnected lock?
The J300 is an economy Grade 2 set built for light-duty, price sensitive commercial work. If the opening sees harder traffic, the Schlage CS210-B500 entrance interconnected lockset is also Grade 2 but rated heavy duty. The Deltana CL300ILC is another Grade 2 interconnected entry set, offered with the Clarendon lever, if you want a different trim look at the same grade.
11) Can I use the Dormakaba J300 on a classroom or office door instead of an apartment entry?
Not really the right tool. The J300 is an interconnected set, meaning lever and deadbolt release together in one motion, which is what apartment and condo entries need. A classroom door wants a classroom-function cylindrical lever instead, and the Schlage S270 is a Grade 2 classroom lock in that form. Use the J300 where a unit entry needs both a latch and a deadbolt with single-motion egress.
12) Is the Dormakaba J300 lockset ADA compliant for a barrier-free unit?
Yes. The J300 meets A117.1 accessibility code and ADA requirements for barrier-free accessibility, and all five trim styles are levers rather than knobs, which is the operable-without-grasping part of that requirement. That makes it usable on accessible units in assisted living and multifamily buildings.
13) Is the Deltana CL300ILC an equivalent to the Dormakaba J300 interconnected lockset?
They are the same class of product. The Deltana CL300ILC is a Grade 2 interconnected lock with an entrance function furnished with the Clarendon lever, and the Dormakaba J300 is an ANSI/BHMA A156.2 Grade 2 certified interconnected lockset. The difference a specifier cares about is lever range and trim: the J300 is offered with the L118, LG, LC, LR, and handed LS levers in Satin Chrome, Satin Nickel, Dark Bronze, and Bright Brass on a 2-1/2 inch rose, while the CL300ILC is the Clarendon lever design. Match the lever family already on the other unit doors before choosing.
14) What do I use for the inside of a door that does not need to lock, if the J300 is on the entry?
For a non-locking inside trim, the Schlage Residential FC94 with Latitude lever and Collins trim is an inside dummy handleset in the Schlage Custom FC-Series - it is pull-only trim with no latch or cylinder. The Dormakaba J300 is a keyed interconnected lockset offered in Single Cylinder and Double Cylinder function options with Keyed Different or Keyed Alike keying. Use the J300 where the door has to latch and key, and the dummy trim only where the leaf is inactive.
15) For a retrofit where the door already has 4 inch or 5-1/2 inch hole centers, which Grade 2 lock fits without new prep?
The Dormakaba J300 fits doors with 4 inch and 5-1/2 inch hole centers, takes 2-3/8 inch or 2-3/4 inch backset, and covers 1-3/8 inch to 1-3/4 inch door thickness, which is what makes it a direct swap on existing interconnected prep. The Schlage CS210-B500 is the other Grade 2 entrance interconnected option to price against it, and the Deltana CL300ILC is a Grade 2 entrance interconnected lock as well. Confirm the existing hole centers on the door before committing, since interconnected prep is not universal across brands.
16) What finishes and lever styles does the Dormakaba J300 come in?
Two finishes are stocked, 626 satin chrome and 690 dark bronze, and each pairs with any of four levers: L118, LG, LC and LR. The handed LS lever is a fifth style in the series. Every one of those lever and finish combinations is available in both single and double cylinder. Trim is a 2-1/2 inch diameter rose with concealed fasteners on the outside, so the exterior face shows no screws.
