SOSS 103CUS26D – Frequently Asked Questions

1) What door or panel thickness does the SOSS 103 invisible hinge need?
The 103 Series is a 1-1/2 inch invisible hinge for material 3/4 inch to 1 inch thick. That range is what makes it a cabinet-door and thin-panel hinge rather than a passage door hinge, since a standard commercial door runs 1-3/4 inches. If you're hanging a 1-3/4 inch door, this is the wrong size in the SOSS line.
2) Does the SOSS 103 hinge stay hidden when the door is closed?
Completely. It's a mortised, fully concealed hinge: with the door shut there's no knuckle, no leaf, nothing visible on either face or the edge. That's the whole point of the 103 in millwork and fine cabinet work where a surface or butt hinge would break up the face. SOSS publishes a cased jamb detail and a hinge location drawing for the 103 so the mortises get cut in the right place.
3) Can SOSS 103 invisible hinges be used on a fire rated door or opening?
The 103 Series carries no fire rating, so keep it off any labeled opening. On a fire rated assembly the hinges are part of the listed hardware set and swapping in an unrated concealed hinge voids the label. Use it on cabinet, millwork, and non-rated wood or metal work.
4) How far will a door on SOSS 103 invisible hinges open?
A full 180 degrees. It's a single action hinge, so the door swings one way to 180 and no further in the opposite direction. For a cabinet or a concealed panel that needs to lay back flat against the adjacent face, that's the swing you want. SOSS publishes an open clearance detail for the 103 showing what room the hinge needs through its arc.
5) Do SOSS 103 hinges come with screws, and do I need anything else to install them?
Wood screws ship with the hinges as standard. If you're mounting into metal you'll want machine screws instead, which SOSS offers as an added-cost item rather than in the box. Beyond fasteners the install is a routed mortise in both the panel edge and the jamb, so the real prep item is a router and template work, not extra hardware. The screw holes are not counterbored.
6) How are SOSS 103 hinges sold, by the piece or by the pair?
By the pair. Two hinges come carded together as one pair, and a full container holds 10 pair. So one order quantity gets you two hinges, not one. Count your openings before ordering: a typical cabinet door takes one pair, but a tall or heavy panel often takes three hinges, which means buying two pair and having one spare.
7) What finishes does the SOSS 103 invisible hinge come in?
Three: 622 matte black, 626 satin chrome, and 606 satin brass. If you're matching concealed hinges to pulls or other trim already in the room, those BHMA finish numbers are what to match against, and all three are available at the 1-1/2 inch size.
8) What is the SOSS 103 hinge made of, and will it hold up in a commercial building?
Zinc and steel construction, and it's catalogued for commercial use, showing up in office fit-outs, healthcare and education millwork, retail casework, and multi-tenant residential. Keep the light duty rating in mind: it earns its place on cabinet doors and concealed panels that get normal daily use, not on high-cycle heavy leaves.
9) Do SOSS 103 hinges have square or radius corners on the leaf mortise?
Radius corners. That matters for prep: a radiused mortise can be routed and left as-is with no chisel work to square the corners, which is why these go in fast with a template. Cut the mortise to the SOSS 103 template and the leaf drops flush.
10) Is the SOSS 103 an electrified hinge for power transfer to a lock or device?
No. The 103 is a purely mechanical hinge with no power transfer and no electric option, and there's no closer built into it. If you need to carry current through the opening to an electric latch or a monitored contact, this hinge won't do it and you'll need a separate power transfer device.
