SOSS 216US26D – Frequently Asked Questions
1) What door applications work with the SOSS 216 series invisible hinge?
The SOSS 216 series handles doors from 1-3/8" minimum thickness up to 95 pounds. Works well for interior doors, cabinet doors, and lightweight entry doors. Verify your door weight and thickness before ordering.
2) How many SOSS 216 hinges do I need per door?
Use two hinges for doors up to 60 pounds. Three hinges for doors 60-95 pounds. Space hinges evenly with top hinge 7" from top of door and bottom hinge 11" from bottom.
3) What mortise depth is required for the SOSS 216?
The SOSS 216 requires a 4-5/8" deep mortise. Use the manufacturer's template for precise mortise cutting. Depth must be exact for proper door alignment and smooth operation.
4) Can the SOSS 216 be used for right or left hand doors?
Yes, SOSS 216 hinges are reversible for right or left hand applications. The same hinge works for both swing directions. No separate left or right hand models needed.
5) What finishes are available for the SOSS 216 series?
Common finishes include satin stainless steel, bright stainless steel, and zinc plating. Finish availability varies by supplier. Check specific finish options when ordering.
6) Will SOSS 216 hinges meet commercial door codes?
SOSS 216 hinges are typically used for residential and light commercial applications. For heavy commercial doors or fire-rated applications, verify code compliance with your local authority before installation.
7) What tools are needed to install SOSS 216 invisible hinges?
