Don-Jo 1636-626 – Frequently Asked Questions

1) What is a Dutch door bolt actually for, and do I need one on both halves?
A Dutch door bolt joins the upper and lower leaves of a split (Dutch) door so the two halves operate as a single door when you want them locked together. The Don-Jo 1636 surface mounts to the face of the door and throws into a strike on the mating leaf, so one bolt per opening is the normal install. It is not a door-to-frame security bolt on its own, it is what makes the two halves move together.
2) Do I have to buy a separate strike for the Don-Jo 1636 Dutch door bolt?
No. The 1636 ships with rim, mortise and T-strikes in the box, so you can mount it surface-applied to a rim strike, mortise the strike into the mating leaf, or use the T-strike depending on how the two halves meet. Pick the strike that matches your door edge condition and set the others aside.
3) How long is the Don-Jo 1636 Dutch door bolt and will it fit on a narrow rail?
The 1636 measures 18 inches long by 1-5/8 inches wide. That 1-5/8 inch width sits flat on most commercial stiles and rails, but the 18 inch body needs a continuous flat run of face material spanning the joint between the two leaves. On a short-rail or heavily glazed Dutch door, measure that run before you commit, because there is no shorter length in the 1636.
4) I only have a few inches of clear rail on my dutch door - is there a shorter dutch door bolt than the Don-Jo 1636?
Yes. The Don-Jo 1636 measures 18 inches long, which needs a long uninterrupted run of door face to mount flat. Where you only have a few inches of clear surface, the Emtek 8516 is a 4 inch dutch door bolt and fits a much smaller mounting area. Measure the flat, obstruction-free surface on both leaves before choosing, since the 1636 spans the meeting line with the bolt body itself.
5) What is the difference between the Don-Jo 1636 dutch door bolt and the Emtek 8516?
Both are dutch door bolts, but they are sized for very different openings. The Don-Jo 1636 is an 18 inch long by 1-5/8 inch wide surface bolt in solid brass, furnished with rim, mortise, and T-strikes and a 1 inch diameter knob. The Emtek 8516 is a 4 inch dutch door bolt. If you are joining the upper and lower leaves of a dutch door and want a long bolt body spanning the meeting rail, the 1636 is the one sized for that; if the stile or rail area only allows a short bolt footprint, the 4 inch Emtek is the shorter-body option.
6) What finishes does the Don-Jo 1636 come in so it matches the rest of my hardware?
Six finishes: 605 polished brass, 613 oil rubbed bronze, 619 satin nickel, 620 antique nickel, 625 polished chrome and 626 satin chrome. For a property standardizing on satin chrome levers and closers, 626 is the match; 605 pairs with polished brass trim. Those are BHMA finish numbers, so they line up with whatever is stamped on your existing hardware.
7) Is the Don-Jo 1636 solid brass or brass plated?
Solid brass through the body, not a plated pot metal casting. That matters on exterior Dutch doors and in kitchens, clinics and coastal facilities where a plated zinc bolt pits and binds. Finish plating sits on top of the brass, so surface wear does not expose a dissimilar base metal.
8) Is this bolt heavy duty enough for a school or hospital Dutch door that gets used all day?
The 1636 is a commercial-rated bolt, built in solid brass with a 1 inch diameter knob sized for repeated hand operation rather than a small residential thumb turn. Don-Jo lists it for office buildings, schools, healthcare, retail service counters and government facilities. For a nurse station or classroom Dutch door cycled constantly, the brass body and full-size knob are the reason to pick it over a light-duty barrel bolt.
9) Can I use a flush bolt in place of the Don-Jo 1636 dutch door bolt?
They are not interchangeable in the same prep. The Don-Jo 1636 is a surface-mounted bolt that screws to the face of the door, so it needs no routing, and it comes with rim, mortise, and T-strikes to land in different frame conditions. A flush bolt is mortised into the door edge and requires machining, and it latches a single leaf to the frame or floor rather than bridging the two leaves of a dutch door. If you want a dutch door bolt in a shorter body instead, the Emtek 8516 is a 4 inch dutch door bolt.
10) For a commercial dutch door in a school or clinic, should I spec the Don-Jo 1636 or the Emtek 8516?
The Don-Jo 1636 is designated for commercial use and is built in solid brass with a 1 inch diameter knob, and it ships with rim, mortise, and T-strikes so it can be adapted to different frame and leaf conditions on the same order - useful when you are standardizing dutch doors across classrooms or exam rooms. The Emtek 8516 is also a dutch door bolt but a 4 inch one, so it suits openings where the mounting surface is short rather than where you want one long bolt body tying the two leaves together.
11) What model do I order and what do I have to specify?
Order Don-Jo model 1636. The only choice you make is finish, one of the six BHMA numbers. There is no handing, no length option and no backset to call out, the bolt is surface applied and all three strike types come with it.
