Don-Jo 1630-626 – 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 the hardware that ties the top and bottom leaves of a dutch door together so the two halves swing as one when you want them to. The Don-Jo 1630 is a surface-mounted version: it screws to the face of the door rather than requiring a mortise pocket, and the 1" diameter knob lets someone throw or retract it by hand without tools. If your door is a single full-height leaf, you want an ordinary surface bolt or flush bolt instead. The dutch door bolt earns its place only where there are two independently hinged halves that need to be locked together, which is why it shows up on service counters, classroom and nurse-station half doors, and stockroom pass-throughs.
2) How much room do I need on the door face to mount a Don-Jo 1630?
The bolt body measures 4-1/2 x 1-5/8 inches, so you need a flat, unobstructed run of face on the leaf a little over 4-1/2 inches long and at least 1-5/8 inches across, plus clearance for the 1" knob to be grasped. On a narrow stile aluminum or glass door, check that 1-5/8 inch dimension against your stile before ordering, because it mounts on the face and not in the edge.
3) What is an equivalent dutch door bolt to the Don-Jo 1630?
The Emtek 8516 is the closest cross-brand counterpart, also built as a dutch door bolt. The Don-Jo 1630 measures 4-1/2 inches by 1-5/8 inches in brass with a 1 inch diameter knob and is furnished with rim, mortise, and T-strikes; the Emtek 8516 is a 4 inch dutch door bolt. Both serve the same purpose - locking the upper and lower leaves of a split door together - so the choice comes down to the plate footprint the door face and existing prep will accept and the strike style already in the opening.
4) The existing bolt plate on my dutch door is shorter than 4-1/2 inches - what should I use instead?
Where the door face or the existing paint line will not take a 4-1/2 inch plate, the Emtek 8516 dutch door bolt is a 4 inch unit and covers a shorter footprint. The Don-Jo 1630 plate is 4-1/2 inches long by 1-5/8 inches wide, so on a retrofit over an older cutout the half inch of extra plate length is the dimension to check against the stile before ordering. Both are surface-applied dutch door bolts, so neither requires a new mortise pocket in the door itself.
5) What finishes does the Don-Jo 1630 dutch door bolt come in?
Five orderable finishes: 605 polished brass, 613 oil rubbed bronze, 619 satin nickel, 625 polished chrome, and 626 satin chrome. If you are matching existing hardware in a building, 626 satin chrome and 613 oil rubbed bronze are the two that most commonly line up with commercial lever and hinge finishes already in place. Pick by the BHMA number rather than the name, since brass and bronze finishes read differently between manufacturers.
6) Is the Don-Jo 1630 solid brass, and will it hold up in a humid or coastal building?
The 1630 is brass. Brass resists corrosion better than plated steel in damp service areas, kitchens, and coastal exposure, which is the usual reason a spec calls for it on a dutch door at a counter or a food service pass-through. In the plated finishes (619, 625, 626) the substrate underneath is still brass, so a scratch through the plating does not start a rust bloom the way it would on a steel bolt.
7) I need a bolt for a pair of doors, not a dutch door - is the Don-Jo 1630 the right part?
No. The Don-Jo 1630 is a dutch door bolt: it joins the upper and lower halves of a single split door so the two leaves operate as one, and it is worked by a 1 inch diameter knob on the face of the door. A pair of swinging doors needs a flush bolt or a surface bolt mounted on the inactive leaf top and bottom, which is a different part. The Emtek 8516 is also a dutch door bolt, so it is a peer for the same split-door application rather than an alternative for a door pair.
8) Is the 1630 dutch door bolt rated for commercial use or is it a residential part?
Commercial. Don-Jo classes the 1630 as a commercial product, which is why it is the one that shows up on school half doors, nurse stations, municipal counters, and multi-tenant service openings rather than a hardware-store surface bolt. For a property manager standardizing across a portfolio, that matters more than the finish: it means the same part number works on the office openings and the residential ones.
