SOSS 216SDB – Frequently Asked Questions

1) What are SOSS SDB steel door hinge reinforcements used for?
The SOSS SDB reinforcements are ready-made all-steel plates that weld into a hollow metal door to carry a SOSS invisible hinge. Instead of a fabricator cutting and forming a reinforcement channel on the bench for every hinge pocket, the SDB plate drops into the prep and gets welded in place. They are a door prep component, not the hinge itself, so you order the hinge separately.
2) Which SOSS SDB reinforcement do I order for a SOSS 218 invisible hinge?
For the 218 and 418 hinges, order the "218 & 418 - Single Piece Insert" version. That one is a single piece rather than a two-part set. The 216/416 and the 220 both take upper and lower pieces instead, so the three are not interchangeable, match the reinforcement to the hinge model number you are installing.
3) Which SOSS invisible hinge models do the SDB reinforcements fit?
Three hinge families are covered: the SOSS 216 and 416, the 218 and 418, and the 220. Each has its own SDB version, ordered by hinge type. If the hinge on your door is outside those three families, the SDB does not apply to it.
4) How many SOSS SDB reinforcements do I need per door?
Count by hinge, not by door. Each bag holds one pair and is priced per pair, covering one hinge location. A door hung on three invisible hinges needs three, one for each pocket, top, middle and bottom.
5) Can SOSS SDB reinforcements be installed without welding?
No. The SDB plates are made to be welded directly into the door, that is the whole point of the part. They suit a shop or a fabricator with welding capability during door prep or a field weld on a hollow metal door. If you cannot weld on the job, this is not the reinforcement method for that opening.
6) Why is the SOSS 216/416 and 220 reinforcement supplied as an upper and lower piece?
A SOSS invisible hinge is routed into both the door edge and the frame as one long mortise, and on the 216/416 and 220 the reinforcement is split into an upper and a lower piece that sit at each end of that pocket. The 218/418 uses one continuous insert instead. Both are sold as a pair per bag, so a single bag reinforces one hinge location.
7) Where do I get the routing dimensions for a SOSS SDB weld-in reinforcement?
Each SDB version has its own SOSS spec sheet for the matching hinge series, one for the 216/416, one for the 218/418 and one for the 220. Pull the sheet for your hinge model before cutting the door, the prep is specific to that series and the reinforcement is sized to it.
8) Are SOSS SDB reinforcements rated for commercial traffic openings?
They are a commercial-grade door hardware item, all steel, and they are used in office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings. For a property manager standardizing invisible hinges across a building, the SDB is the piece that keeps a high-cycle steel door from working the hinge pocket loose.
