SOSS 101SSUS32DPB – Frequently Asked Questions

1) Is the SOSS 101SS hinge OK for an exterior or wet location?
It is. The 101SS is complete 316 stainless steel, which is the marine-grade alloy, and the listed applications include exterior as well as metal and wood. That makes it a reasonable pick for coastal exposure, pool enclosures, or a washdown area where a plated or zinc hinge would bloom rust. The finish is US32DPB satin stainless.
2) How many SOSS 101 invisible hinges do I need per door, and where do they go?
The 101SS is sold one hinge to a bag, so a door takes multiple units ordered individually. Hinge count and placement depend on door height and weight, and SOSS publishes a hinge location drawing for the 101 that gives the layout: https://zensupply.com/content/pdf/soss/hinge_location.pdf. There is also a cased jamb detail at https://zensupply.com/content/pdf/soss/cased_jamb_detail.pdf for the jamb-side mortise.
3) What size mortise does the SOSS 101SS need in the door edge?
The 101SS is the 1 inch size in the SOSS 101 Series, with radius corners on the leaves. Router the pocket to match those radiused ends rather than squaring them off with a chisel, or the hinge will sit loose in the mortise. The dimensioned model drawing is at https://zensupply.com/content/pdf/soss/soss101.pdf.
4) Do I need to order screws separately for a SOSS 101SS invisible hinge?
Wood screws ship in the bag with each hinge, one hinge per bag. If you're mounting into metal you'll want machine screws, and those are a separate additional-charge item rather than something included. Plan the fastener call before the install day if the substrate is steel or aluminum.
5) Will a SOSS 101 invisible hinge let the door lay flat against the wall?
It opens a full 180 degrees as a single action hinge, so the leaf swings all the way back flat. That is the reason people specify these on cabinet doors, wall panels, and access doors where a butt hinge would leave the door standing proud. SOSS publishes an open clearance detail showing the swing envelope: https://zensupply.com/content/pdf/soss/open_clearance_detail.pdf.
6) Is the SOSS 101 hinge handed, and do I have to specify left or right?
There is no handing to call out. The 101SS is offered as a single model with one configuration, so the same hinge serves a left or right swing depending on which side of the opening you mortise it into. That also means one part number covers a whole building's worth of openings, which simplifies keeping spares on the shelf.
7) Can I put a closer or electrified power transfer on a SOSS 101 invisible hinge?
Neither. The 101SS is a plain mechanical hinge with no closer function and no power transfer path through it, and it carries no electronic option. If you need to run current to an electric strike or a latch in the leaf, the wiring has to come through a separate electric hinge or a door loop, not through this one.
8) Does the SOSS 101SS hinge have countersunk screw holes?
The holes are not counterbored, so the screw heads seat in a standard countersink flush with the leaf face. If your detail called for a counterbored hole to take a shouldered fastener or a plug, this is not that hinge.
