Don-Jo 1634-626 – Frequently Asked Questions

1) What is a Dutch door bolt and when do I need one instead of a regular surface bolt?
A Dutch door bolt is what ties the two leaves of a Dutch door together so the top and bottom halves swing as one unit when you want them to, and release so the top half can open independently when you don't. A regular surface bolt just locks a door leaf to the frame or threshold. The Don-Jo 1634 is surface mounted on the face of the door and throws into a strike on the opposing leaf, so if you have a service counter or classroom Dutch door where the halves need to be coordinated, this is the part. If your door is a standard single leaf and you just need to hold an inactive door shut, a surface bolt or flush bolt is what you want instead.
2) Does the Don-Jo 1634 Dutch door bolt come with the strike, or do I have to order that separately?
All three strikes come in the box. The 1634 is furnished with a rim strike, a mortise strike and a T-strike, so you pick whichever suits the way the opposing leaf is prepped rather than ordering a strike to match. That covers a surface-applied condition, a mortised-in condition, and a T-strike application, which is why one part number covers a range of Dutch door frame and leaf conditions without a second lookup.
3) How long is the Don-Jo 1634 Dutch door bolt and how much face of the door does it cover?
The 1634 measures 12 x 1-5/8 inches, so it takes up a foot of length across the meeting point of the two leaves and a hair over an inch and a half of width. That is a substantial run of face plate, so before you commit, check you have a clear 12 inch stretch on the door face at the bolt location with no lite frame, panel molding, or existing hardware in the way. The operating knob is 1 inch in diameter and projects off that plate.
4) I need a shorter Dutch door bolt than 12 inches. What else is there?
The Emtek 8516 is a 4 inch Dutch door bolt, which is the option when a 12 inch plate will not fit the face of the leaf or you want a less prominent piece of hardware on a decorative door. It does the same job of coordinating the two halves. Go with the Don-Jo 1634 at 12 x 1-5/8 inches when you want the longer commercial-duty plate and the full rim, mortise and T-strike package included.
5) Can I use the Don-Jo 1634 Dutch door bolt as a regular flush bolt on a pair of doors?
No, and that is a common mix-up. The 1634 is a surface-applied Dutch door bolt, meaning the plate sits on the face of the door and the bolt throws horizontally into the opposing leaf of a Dutch door. A flush bolt mortises into the edge of an inactive leaf and throws vertically into the head or threshold on a pair of doors. If you are securing the inactive leaf of a double door opening, you need a flush bolt or a surface bolt for that application, not a Dutch door bolt.
6) The Don-Jo 1634 dutch door bolt is 12 inches long and my dutch door rail is too narrow for it. What shorter dutch door bolt can I use?
The Emtek 8516 is a dutch door bolt in a 4 inch length, so it mounts on a much narrower rail than the 12 inch by 1-5/8 inch Don-Jo 1634. Both are surface-applied dutch door bolts that join the upper and lower leaves so the pair swings as one door. Measure the flat rail area where the leaves meet before choosing: the 1634 needs a full 12 inches of uninterrupted surface plus clearance for its 1 inch diameter knob, while the 4 inch Emtek 8516 suits a shallow rail or a door with glass or a panel close to the meeting line.
7) Is the Don-Jo 1634 Dutch door bolt solid brass or plated steel?
Brass. The 1634 is built from brass rather than plated steel, which is why it holds up in humid or coastal conditions and in openings that get wiped down constantly, like healthcare and food service counters. The finish is applied over that brass substrate, so wear at the knob, which is the spot that gets handled every time, exposes more brass rather than raw steel.
8) What finishes does the Don-Jo 1634 Dutch door bolt come in, and which one matches my existing lever hardware?
Six finishes, and they are all BHMA numbers so you can match them straight off whatever is already on the opening: 605 polished brass, 613 oil rubbed bronze, 619 satin nickel, 620 antique nickel, 625 polished chrome, and 626 satin chrome. If the building standard is 626 satin chrome, which is the most common commercial spec, order the 626 and it will read the same as the levers and closers. For a bronze-toned opening, 613 is the darker option and 620 the antique nickel.
9) Is the Don-Jo 1634 rated for commercial use or is it a residential-duty part?
Commercial. The 1634 is classed as commercial hardware, not residential, which is the distinction that matters when you are specifying for a school corridor, a hospital nurse station, or a municipal service counter where the bolt gets thrown many times a day. Combined with the brass body, that is what separates it from the lighter residential Dutch door bolts sold at retail.
10) Which dutch door bolt comes with the strikes included, the Don-Jo 1634 or the Emtek 8516?
The Don-Jo 1634 is furnished with Rim, Mortise and T-Strikes in the box, so one part number covers an applied stop, a mortised jamb prep or a T-strike condition without a separate strike order. The Emtek 8516 is a 4 inch dutch door bolt and its strike package is a separate question to confirm before you order. If you are standardizing across a building where the door and frame conditions are not identical opening to opening, the three-strike package on the brass 1634 is what keeps it to a single SKU.
11) I need a dutch door bolt in oil rubbed bronze to match the rest of the hardware. What are my options?
The Don-Jo 1634 dutch door bolt is made in 613 oil rubbed bronze, and in five other finishes alongside it: 605 polished brass, 619 satin nickel, 620 antique nickel, 625 polished chrome and 626 satin chrome. That six-finish range is the reason to spec the 1634 when the bolt has to disappear into an existing finish scheme rather than stand out. The comparable Emtek 8516 is a dutch door bolt in a 4 inch length, which is the one to look at if rail width, not finish, is the governing constraint.
12) How is the Don-Jo 1634 Dutch door bolt packaged if I am ordering for multiple openings?
The 1634 is sold in shelf packs of 10. That suits a property manager or contractor doing a run of Dutch doors across a building, since one pack covers ten openings in a single finish and every unit carries its own rim, mortise and T-strike set. If you are standardizing a facility, order the whole run in one finish code so the openings read consistently.
