Cal-Royal DDSB4-US10B – Frequently Asked Questions

1) What length Dutch door bolt do I need for a Dutch door top half?
The Cal-Royal DDSB comes in 4, 8, 12, 18 and 24 inch lengths (DDSB4, DDSB8, DDSB12, DDSB18, DDSB24). Pick by how far the bolt has to reach from the mounting point to the strike location: a short 4 or 8 inch bolt is enough where the bolt sits right at the meeting rail of the two door leaves, while the 18 and 24 inch versions are for running the bolt up a tall leaf to a head strike or down to the floor. All five lengths come in every one of the seven finishes.
2) Do I have to buy a strike separately for the Cal-Royal DDSB Dutch door bolt?
No separate strike order. Each DDSB bolt ships with both a mortise strike and a universal strike in the box, so you can either mortise the strike into the frame or edge of the mating leaf for a flush look, or surface-apply the universal strike when you do not want to cut the wood or the frame will not take a mortise. That covers most door and frame preps without a second line on the order.
3) What is a comparable Dutch door bolt to the Cal-Royal DDSB in a 4 inch length?
The Emtek 8516 is a Dutch door bolt offered in a 4 inch length, which lines up with the 4 inch Cal-Royal DDSB. Both are Dutch door bolts, the hardware that pins the upper and lower leaves of a split door together so the pair swings as one. The DDSB differs in that it is solid brass, carries a 1 1/8 inch decorative knob, and ships with both a mortise strike and a universal strike in the box, so the same part can be set into a mortised frame prep or a surface-applied one. If you need a bolt only for a short reach at the meeting rail, the 4 inch DDSB and the Emtek 8516 cover the same job at the same length.
4) I need a Dutch door bolt longer than 4 inches - what are my options?
The Cal-Royal DDSB runs in 4, 8, 12, 18, and 24 inch lengths, so anything past a short 4 inch reach stays within the same model: DDSB8, DDSB12, DDSB18, and DDSB24. The Emtek 8516 Dutch door bolt is a 4 inch bolt, so a longer throw means moving to one of the longer DDSB sizes. Length matters when the bolt has to reach past a thick meeting rail, a rail-and-stile panel, or an applied molding to land on the strike, and the 18 and 24 inch sizes give a contractor room to place the knob at a comfortable operating height while the rod still engages well below.
5) Is a Dutch door bolt the right thing to lock the two halves of a Dutch door together?
Yes, that is exactly the job. A Dutch door bolt is a surface-mounted sliding bolt fitted across the meeting rail so the top and bottom leaves throw together and operate as one door. The Cal-Royal DDSB does that with a decorative knob you slide by hand. If instead you want a bolt to hold a normal door leaf into the head or the floor, that is a flush bolt or a plain surface bolt, not a Dutch door bolt.
6) Will the Cal-Royal DDSB hold up in a commercial building or is it a residential part?
It is specified as commercial hardware, solid brass throughout, and conforms to ANSI/BHMA 156.16, the standard covering auxiliary hardware including surface bolts. Cal-Royal lists it for office buildings, schools, healthcare, retail, industrial and warehouse, multi-tenant residential, and government work. Solid brass rather than plated pot metal matters on a bolt that gets slid by hand several times a day.
7) I am standardizing Dutch door hardware across a whole property. Can I run one bolt model on every opening?
Yes. The DDSB is one model in five lengths and seven finishes, so you can hold a single finish across the property and vary only the length to suit each door, and every unit arrives with both strike types so odd frame conditions in older buildings do not force a second part number. That keeps the attic stock to one finish family and a couple of lengths.
8) I want a Dutch door bolt that matches the brass hardware already on the door - which one?
The Cal-Royal DDSB is solid brass and comes in seven architectural finishes: US1 flat black, US3 polished brass, US5 antique brass, US10B antique bronze oiled, US15 satin nickel, US15A satin nickel oxidized, and US26 polished chrome, each offered across the 4, 8, 12, 18, and 24 inch lengths. That range lets a property manager hold one finish code across a set of Dutch doors regardless of the bolt length each opening needs. The Emtek 8516 is the comparable Dutch door bolt at 4 inches if the rest of the opening is already Emtek.
9) Can I use a Dutch door bolt like the Emtek 8516 or Cal-Royal DDSB as a flush bolt on a pair of doors?
No - a Dutch door bolt is not a flush bolt for an inactive leaf. Both the Cal-Royal DDSB and the Emtek 8516 are Dutch door bolts, made to join the top and bottom halves of a split door so they operate together. A pair of swinging doors needs a flush or surface bolt made for an inactive leaf, mounted top and bottom to the frame head and floor. The DDSB does ship with mortise and universal strikes, which covers different Dutch door frame preps, but the strikes do not change what the bolt is for.
10) Is the Emtek 8516 the same as a Cal-Royal DDSB for a commercial opening?
They are both Dutch door bolts and the Emtek 8516 matches the 4 inch size, but the Cal-Royal DDSB is specified for commercial use and conforms to ANSI/BHMA 156.16 for surface bolts. On a school, healthcare, or government job where the spec calls out an ANSI/BHMA-conforming surface bolt, the DDSB is written to that standard; the 8516 is catalogued only as a Dutch door bolt. If the drawing carries a BHMA line item, that is the difference that decides it.
11) Is the Cal-Royal DDSB easy to operate for someone with a full load in their hands?
The bolt is thrown by a 1-1/8 inch diameter decorative knob rather than a small thumb tab, which gives you something to grip with a gloved hand or a knuckle. It is a manually operated surface bolt, so it does not release with the lockset; whoever passes through the Dutch door still has to slide it.
