SOSS 216ICUS26D – Frequently Asked Questions

1) Is the SOSS 216IC hinge approved for a fire door?
Underwriters Laboratories labeled the 216IC for swinging fire doors and frames carrying a 20 minute rating. The label covers hollow metal, sheet metal, tin clad, steel composite and wood core doors, which is the usual range for a 20 minute corridor or tenant-entry opening. Note that this is a self-closing hinge, so on a 20 minute opening it is doing the closing job as well as the hanging job.
2) What is the difference between an invisible spring closer hinge and a regular full mortise spring hinge?
Sightline and prep. The SOSS 216IC is a 6-1/4 inch invisible hinge, so with the door shut nothing shows on either face, and the closer buries inside the door or the jamb. It needs a routed pocket to do that. A conventional full mortise spring hinge such as the Hager 1250 or the McKinney 1502 in 4-1/2 by 4-1/2 mortises into the door edge and frame the way a butt hinge does and its barrel is visible in the gap, but the prep is standard hinge prep. Pick the 216IC when the opening is on show or the architect specified concealed hardware. Pick the butt-style spring hinge when you are working existing hinge cutouts.
3) Can a Pemko Markar spring loaded continuous hinge be used in place of a SOSS 216IC on a full sized entry door?
They are built for different openings. The Pemko Markar FM400 Series is a full mortise spring loaded continuous hinge with 80 lb load capacity for toilet partitions, the FM900 Series is a spring loaded continuous hinge with 80 lb capacity for toilet partitions, the FS402 Series is a spring loaded continuous hinge for toilet partitions with 80 lb load capacity, and the FS902 Series is the same partition hinge in 304 stainless steel with 80 lb capacity. The SOSS 216IC is a 6-1/4 inch invisible spring closer for full sized entry doors in metal and wood, 1-3/8 inch minimum door thickness, UL labeled for swinging fire doors and frames with a 20 minute fire rating.
4) What is the closest alternative to the SOSS 216IC when the door still has to self-close but the closer does not have to be hidden?
The SOSS 216IC is a 6-1/4 inch invisible spring closer that mortises into the door itself or into the jamb, so nothing shows on either face when the door is closed, and the closure rate is adjusted with an allen wrench after installation. Where a visible hinge is acceptable, the same self-closing duty is handled by full mortise spring hinges: the Hager 1250 is a full mortise spring hinge in standard weight steel construction, the Hager 1150 is the standard weight stainless steel full mortise version, and the McKinney 1502 is a 4-1/2 inch by 4-1/2 inch square corner full mortise standard weight spring hinge. Those three hang as conventional butt hinges with leaves on the hinge edge; the 216IC carries its closer inside the mortise.
5) The existing doors have radius corner hinge preps - which spring hinge matches, and does the SOSS 216IC?
The SOSS 216IC is a radius corner hinge, but it seats in an invisible hinge mortise cut into the door or the jamb rather than in a butt hinge prep. Where the opening already carries butt preps with rounded corners, the radius corner spring hinges are the Hager 1251 with 1/4 inch round corners and the Hager 1252 with 5/8 inch round corners, the Orca Hardware SPR4014 at 4 inch by 4 inch with a 1/4 inch radius and the SPR4058 at 4 inch by 4 inch with a 5/8 inch radius, the Deltana DSH35R4 single action spring hinge at 3-1/2 inch by 3-1/2 inch with a 1/4 inch radius in steel, and the BEST RD2060R radius corner standard weight spring hinge with a removable pin.
6) Is the SOSS 216IC sold as a pair or as a single hinge?
One hinge per box, priced each. Order the quantity your opening needs rather than assuming a box covers the door. That is worth checking against habit, because plenty of spring hinges ship two to a package, the Emtek 95013 among them, and buyers who order 'two' end up with four leaves on one product and two on another.
7) How do you adjust the closing speed on a SOSS invisible spring closer hinge?
With an allen wrench, after the hinge is in the door. The closure rate on the 216IC is fully adjustable and you do not have to pull the closer out of the mortise to change it, so a maintenance tech can slow a door that is slamming or speed one that is hanging open without taking the door down or cutting anything.
8) Does the SOSS 216IC hinge get mortised into the door or into the frame?
Either. The 216IC closer can be housed inside the door itself or inside the jamb, which gives you an out when the door leaf is too thin at the edge or the frame is the easier piece to rout. SOSS publishes a hinge location detail and a cased jamb detail for the 216 Series, and those are the drawings to route from. It opens a full 180 degrees as a single action hinge.
9) I need a door that swings both directions. Will the SOSS 216IC work?
No. The 216IC is a single action hinge, meaning the door swings one way only, out to a full 180 degrees. For a door that has to push both directions, look at a double action spring hinge instead: Deltana makes the DASHS double action saloon hinge in 4, 5 and 6 inch heights, and the DASH95 double action spring hinge with solid brass cover plates. Neither of those is an invisible hinge, so the hardware will show.
10) Can the SOSS 216IC hinge carry wiring to an electrified lock or exit device?
No. The 216IC has no power transfer and is not an electronic hinge, so it will not run wire from the frame into the door. If the opening has an electrified lock, an electric latch retraction device or a request-to-exit switch in the lock, you need a separate power transfer path, an electric power transfer, a door loop, or an electric hinge on one of the other leaves. The 216IC handles the swing and the closing only.
11) Do I need to buy screws for a SOSS 216IC, and will it go into a metal door?
Wood and machine screws both come in the box, so the fasteners for a wood door and for a hollow metal or sheet metal door are already covered. The 216IC is UL labeled for hollow metal, sheet metal, tin clad, steel composite and wood core doors, and it is rated for full sized entry openings in metal and wood. What is not in the box is the routing, the pocket has to be cut in the door edge or the jamb before the hinge goes in.
12) How much wall clearance does an invisible hinge need to swing open?
Enough that it is worth checking before you commit, because an invisible hinge pivots differently from a butt hinge and the leaf edge travels out as it opens. SOSS publishes an open clearance detail and a 90 degree open drawing for the 216 Series, plus a hinge location detail, and those give you the geometry for a door running against a return wall, a cabinet, or a second door in a tight vestibule. The 216IC itself will go the full 180 degrees if the opening allows it.
13) Is the SOSS 216IC heavy duty enough for a high traffic commercial door?
It is rated heavy duty and commercial, built out of zinc and steel. That puts it a step above most of the butt-style spring hinges in the same job class, the Hager 1250 and 1251, the McKinney 1502 and the Orca 4014 and 4058 series are all catalogued medium duty. If the opening is a tenant corridor, a stairwell vestibule or a back-of-house door that cycles all day, the heavy duty rating is the reason to spend on the 216IC over a medium duty spring butt.
14) Which spring hinges besides the SOSS 216IC carry a UL label?
The SOSS 216IC is UL labeled for use on hollow metal, sheet metal, tin clad, steel composite or wood core swinging fire doors and frames with a 20 minute fire rating. Two other UL spring hinges sit in the same class: the Design Hardware UL Spring Hinge, a medium duty spring hinge, and the Emtek 95013, sold as a pair, 3-1/2 inch by 3-1/2 inch with square corners, UL listed, plated steel. The 216IC differs in form - it is the concealed closer type rather than a butt hinge.
15) How does the duty level of the SOSS 216IC compare to other spring hinges?
The SOSS 216IC is a heavy duty commercial hinge built of zinc and steel. The full mortise butt-style spring hinges alongside it are medium duty: Hager 1150, Hager 1250, Hager 1251 and Hager 1252 are all medium duty standard weight, the McKinney 1502 is medium duty standard weight, the Orca Hardware SPR4014, SPR4040, SPR4058 and SPR4058Z are medium duty, the BEST 2060R and RD2060R are medium duty standard weight, and the Design Hardware UL Spring Hinge is medium duty.
16) Which spring hinges have square corners instead of the radius corner on the SOSS 216IC?
The SOSS 216IC is a radius corner hinge. The square corner spring hinges are the BEST 2060R, a square corner standard weight plain bearing spring hinge with a removable pin, the Emtek 95013 at 3-1/2 inch by 3-1/2 inch with square corners in plated steel, the McKinney 1502 at 4-1/2 inch by 4-1/2 inch square corner full mortise standard weight, and the Orca Hardware SPR4040 at 4 inch by 4 inch square corner.
17) Is the BEST 2060R a direct spring hinge equivalent to the SOSS 216IC?
They work differently. The BEST 2060R is a plain bearing spring hinge with a removable pin, square corners, standard weight, and its product function reads plain bearing; the BEST RD2060R is the radius corner version, also plain bearing with a removable pin. Both are butt hinges that hang on a pin at the hinge edge. The SOSS 216IC is a spring closer hinge with an adjustable closure rate set by an allen wrench after installation, mortised into the door or the jamb so the closer is hidden from either side when the door is closed.
18) How does the size of the SOSS 216IC line up against other spring hinges?
The SOSS 216IC is a 6-1/4 inch hinge. Among the butt-style spring hinges, the Emtek 95013 and the Deltana DSH35R4 are 3-1/2 inch by 3-1/2 inch, the Orca Hardware SPR4014, SPR4040, SPR4058 and SPR4058Z are 4 inch by 4 inch, the McKinney 1502 is 4-1/2 inch by 4-1/2 inch, and the Deltana DASHS double action saloon hinge comes in 4 inch, 5 inch and 6 inch heights. The 216IC dimension describes the invisible hinge body that sits inside the mortise rather than a visible leaf.
19) The frame has a Z hole pattern - which spring hinge is drilled for it?
The Orca Hardware SPR4058Z is a 4 inch by 4 inch spring hinge with a 5/8 inch radius corner and a Z hole pattern; the Orca SPR4058 is the same 4 inch by 4 inch 5/8 inch radius corner hinge without that pattern designation. Hole pattern is not a factor on the SOSS 216IC, which mortises into a pocket in the door or the jamb and ships with wood and machine screws for the installation.
20) What finishes does the SOSS 216IC invisible hinge come in?
Five, and they are the standard BHMA numbers so they line up with lockset and lever finishes across a building: 606 satin brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black and 626 satin chrome. Worth remembering that the 216IC is invisible with the door closed, so the finish only reads when the door is standing open. If you are matching a floor of existing openings, match to the lever and the strike rather than agonizing over the hinge.
21) What are the material differences between the SOSS 216IC and comparable spring hinges?
The SOSS 216IC is built of zinc and steel. Among the comparable spring hinges, the Hager 1150 is standard weight stainless steel and the Hager 1250, 1251 and 1252 are standard weight steel construction, the Pemko Markar FS902 Series is 304 stainless steel, the Emtek 95013 is plated steel, the Deltana DSH35R4 and DSH35R4-A are steel, and the Deltana DASH95 carries solid brass cover plates.
