SOSS 203SSUS32DPB – Frequently Asked Questions

1) Will a SOSS 203 invisible hinge work on a 3/4 inch thick door?
Yes. The 203 Series is built for wood or metal doors with a minimum material thickness of 3/4 inch, up to 1 inch thick. Below 3/4 inch there isn't enough material to take the mortise, so a thinner cabinet door needs a smaller invisible hinge instead. The hinge body itself is the 1-3/4 inch size.
2) Does the SOSS 203 hinge open a full 180 degrees?
It does. The 203 is a single action hinge with a full 180 degree swing, so the door lays back flat against the adjacent face. Single action means it swings one way only, not both, so plan the mortise on the side you want the door to open toward.
3) Is the SOSS 203 stainless hinge suitable for an exterior door?
Yes, that is the point of the stainless version. It is complete 316 stainless steel, which is the corrosion grade you want on exterior openings and coastal or wash-down interiors. Listed applications are cabinet, exterior, metal and wood. Note it is a light duty hinge, so it belongs on cabinet doors, panel doors and light leaves, not a heavy commercial entrance.
4) Can I use a SOSS 203 invisible hinge on a fire rated door?
No. The 203 Series carries no fire rating, so keep it off rated openings and specify a fire rated hinge where the door assembly has to hold a label. It is fine on non-rated cabinet, millwork, exterior and panel work.
5) What screws come with a SOSS 203 invisible hinge, and do I need anything else?
Wood screws are in the bag with every hinge. If you are hanging a metal door or leaf you'll want machine screws, which SOSS supplies as an added-cost option, so order those separately. The screw holes are not counterbored.
6) Do I have to specify handing when ordering a SOSS 203 invisible hinge?
No handing to call out. The 203 is a symmetrical invisible hinge, mortised into the edge of the door and the jamb, so the same part works left or right. What you do have to get right is which face the door swings toward, since it is single action, and the mortise routing, which is laid out in the SOSS hinge location and cased jamb detail drawings.
7) Why choose an invisible hinge like the SOSS 203 over a standard butt hinge?
Nothing shows when the door is closed. A butt hinge leaves knuckles on the edge of the opening; the 203 mortises fully into the door and jamb so the joint reads as a clean line, which is why it turns up on custom millwork, concealed panels and flush cabinetry. The trade-off is prep: a butt hinge screws to the face of the rabbet, while the 203 needs a routed pocket in both the door and the frame, cut to the SOSS template. If you can't rout a precise mortise, or the leaf is heavy, use a butt hinge; the 203 is a light duty hinge.
8) Will a SOSS 203 hinge clear an inset door or an adjacent wall when it opens?
Clearance depends on how the door sits in the opening, and SOSS publishes an open clearance detail plus a cased jamb detail for the 203 that give the swing geometry. Check those against your reveal and any adjacent return before you rout, because the concealed body needs its pocket depth in both the 3/4 to 1 inch door and the jamb.
9) Can a SOSS 203 hinge carry a door closer or electric power transfer for an access control device?
Neither. The 203 is a purely mechanical hinge with no power transfer path and no built-in closer, so an electrified lock or strike on that door needs a separate power transfer hinge or door loop, and any closing function needs its own closer.
10) What finish is the SOSS 203SS invisible hinge?
Satin stainless steel, US32DPB, over complete 316 stainless construction. Since the hinge is concealed when the door is closed, the finish matters mainly for how the edge reads when the door stands open and for corrosion life in wet or exterior conditions.
11) Does the SOSS 203 hinge have square or radius corners on the mortise?
Radius corners. That is good news for the shop, because a router with a matching bit cuts the pocket directly with no chisel work to square the ends.
