Don-Jo 1639-626 – Frequently Asked Questions

1) Will the Don-Jo 1639 dutch door bolt work on my frame, or do I need a special strike?
Strikes come in the box, all three types: rim, mortise, and T-strike. That covers a surface-applied strike on the face of the opposite panel, a mortised strike cut into it, and a T-strike, so the same bolt handles wood or hollow metal panels without a separate strike order. Pick the strike that suits the panel prep and set the other two aside.
2) Is a 36 inch dutch door bolt too long for my door panels?
The 1639 measures 36 inches long by 1-5/8 inches wide, so it is sized to run the height of a standard dutch door panel rather than sit as a short surface bolt near the meeting rail. If your panels are short, or you only need a stub bolt at the joint between the two leaves, a 4 inch dutch door bolt like the Emtek 8516 is the shorter approach. Measure the panel before you commit to the 36 inch bolt, since it cannot be cut down without losing the throw.
3) What is the difference between a Don-Jo 1639 dutch door bolt and an Emtek 8516 dutch door bolt?
Both are dutch door bolts, so both join the upper and lower leaves of a split door so the pair swings as one. The difference is length: the Don-Jo 1639 is a 36 inch bolt, 1-5/8 inches wide, while the Emtek 8516 is a 4 inch bolt. The 1639 runs a long span across the meeting rail and comes in a brass body with rim, mortise, and T-strikes; the 8516 is the short-body approach. If you want the bolt to be a discreet piece of hardware at the meeting rail, the 4 inch Emtek is the shorter form; if you want a bolt that reaches well up the panel, the 36 inch Don-Jo is the longer one.
4) I need a shorter dutch door bolt than 36 inches - what else works?
The Emtek 8516 dutch door bolt is a 4 inch bolt and performs the same job of locking the two leaves of a dutch door together. Reach for it when the meeting rail area is short, when a rail-mounted lock or a shelf crowds the panel, or when a long bolt body would run into glazing or a panel joint. The Don-Jo 1639 is the 36 inch bolt and is the choice where a full-span bolt is wanted. Both are dutch door bolts, so the mounting concept is the same; the span across the door is what changes.
5) Is the Don-Jo 1639 solid brass or brass plated?
Solid brass is the substrate, not a plating over steel. That matters for exterior dutch doors and for coastal or wash-down interiors where a plated steel bolt corrodes at the throw and starts binding. The finish over it is what you choose separately.
6) What finishes does the Don-Jo 1639 dutch door bolt come in?
Five orderable finishes: 605 polished brass, 613 oil rubbed bronze, 620 antique nickel, 625 polished chrome, and 626 satin chrome. For a property manager matching existing openings, 626 satin chrome is the usual match to satin chrome lever hardware and 613 to dark bronze. Order the finish code, not the color name, since 625 and 626 read nearly the same on a spec sheet and very differently on the door.
7) Do I need to specify handing on the Don-Jo 1639 dutch door bolt?
No handing to specify. The 1639 is ordered by finish only, so the single decision on the order is which of the five finish codes you want. The bolt mounts to the face of the door and the strike goes on the opposing leaf, which works the same on a left or right hand dutch door.
8) Is a surface bolt the same thing as a dutch door bolt?
No, and swapping one for the other will leave a dutch door working wrong. A dutch door bolt such as the Don-Jo 1639 or the Emtek 8516 ties the upper and lower leaves of a split door to each other so the two halves operate as a single door when you want them to and separate when you throw the bolt. A plain surface bolt secures a door leaf to the frame, head, or sill instead. If the requirement is to make the top and bottom halves of a dutch door swing together, it is a dutch door bolt you want, not a generic surface bolt.
9) Is the 1639 dutch door bolt rated for a commercial opening or is it residential trim?
Commercial is how the 1639 is classed, and the solid brass body backs that up for service counters, classroom dutch doors, and healthcare pass-throughs that cycle all day. The 1 inch knob is sized for a gloved hand rather than a decorative thumb turn.
10) How many Don-Jo 1639 bolts come in a pack?
The 1639 ships in shelf packs of 10. Worth knowing if you are doing a single door repair versus standardizing a floor of dutch doors, since one opening takes one bolt.
