Ives IVE-S48-B26D – Frequently Asked Questions

1) What is an Ives S48 mortise dutch door bolt used for?
The S48 is a mortise bolt for dutch doors, the split-leaf openings where the top and bottom halves swing independently. It locks the two leaves together so the door operates as one full-height door when you want it to, and releases so the top half can swing on its own. The chamfered end on the rod pulls the two leaves tight as it throws, so they close flush rather than sitting proud of each other. A 1 inch diameter knob operates it by hand.
2) Do I have to buy the strike separately for the Ives S48 dutch door bolt?
No. Every S48 ships with all three strikes: a Standard Strike (SS), a Mortise Strike (MS), and a Universal Strike (US), plus wood screws. You pick the one that suits the leaf you are bolting into on the job and set the other two aside. Nothing else has to be ordered to complete a wood door install.
3) My dutch door leaves do not line up perfectly. Will a mortise dutch door bolt still throw?
That is the specific condition the S48 strike opening is cut for. Ives builds extra tolerance into the strike opening to take up misalignment between the two leaves and keep the bolt from binding as it throws. It is not unlimited, but a door that has settled or a pair of leaves that sit slightly out of plane is the normal case here, not an exception. The chamfered rod end also does work for you: it cams the leaves back into line as the bolt goes home.
4) Is the Ives S48 a surface bolt or does it get mortised into the door edge?
Mortised. The S48 is a mortise bolt, so the body is routed into the edge of the door leaf and only the knob and faceplate show. That means door prep with a router or chisel, not just screwing a plate to the face. If you want something that mounts to the surface of the door with no routing, you want a surface bolt instead, which is a different part. The tradeoff is appearance and snag resistance: mortised hardware sits flush.
5) Is the Ives S48 bolt rated for a commercial building or is it residential hardware?
Ives classes the S48 as residential. It is brass and steel and it holds up in light commercial work, multi-family, and millwork jobs, but if you are specifying hardware for a high-traffic commercial opening under a Grade 1 spec, this is not the part to write in. For a dutch door in an apartment, an office suite, a historic renovation, or a custom interior, it is sized right.
6) Does the Ives S48 dutch door bolt meet ANSI/BHMA standards?
The S48 meets ANSI/BHMA A156.16, the standard covering auxiliary hardware, which is the family bolts and catches like this fall under. If your submittal or spec calls out A156.16 for door bolts, this one answers it. That is the only standard Ives states for it, so do not carry it into a fire door schedule on the strength of that citation.
7) What finishes does the Ives S48 dutch door bolt come in, and can I match the rest of my door hardware?
Six finishes, ordered by BHMA number: 605 bright brass, 609 blackened brass, 613 satin bronze oil-rubbed, 619 satin nickel, 625 bright chrome, and 626 satin chrome. Those are the standard BHMA codes, so if your levers and hinges are specified as 626 or 613, order the S48 in the matching number and it lands in the same family. For a property manager standardizing a building, 626 satin chrome (part S48-B26D) and 613 oil-rubbed bronze (S48-B10B) are the two that most commonly match existing interior trim.
8) How big is the Ives S48 bolt faceplate, and how much door edge do I need?
Ives gives the S48 dimension as 1-3/4 x 1/2 inches. That is a small footprint, which matters on a dutch door because the mortise goes into the meeting edge of the leaf and you are often working with a rail rather than a full stile. Lay the template on the actual rail before you route.
9) What is the exact part number to order an Ives dutch door bolt in oil-rubbed bronze?
S48-B10B is the 613 satin bronze oil-rubbed version. The rest of the line runs S48-B3 (605 bright brass), S48-B5 (609 blackened brass), S48-B15 (619 satin nickel), S48-B26 (625 bright chrome), and S48-B26D (626 satin chrome). Base model is S48; the suffix after the dash is the finish.
10) Can I use the Ives S48 on something other than a dutch door, like a pair of french doors or a cabinet?
Yes, within reason. Ives lists the S48 for dutch doors and similar applications, and the same logic applies anywhere you need one leaf held fixed while the other operates: residential interior doors, specialty and custom millwork, historic renovation work. The chamfered rod and the strike tolerance are tuned to pulling two leaves together, so it is at its best where the two halves need to close flush. It is residential-class hardware, so keep it off high-cycle commercial openings.
