SOSS 418US26D – Frequently Asked Questions

1) What is the minimum door thickness required for the SOSS 416 invisible hinge?
The SOSS 416 requires a minimum door thickness of 1-3/8 inches. This measurement applies to both the door and frame material where the hinge will be mortised.
2) What door weight capacity does the SOSS 416 support?
Each SOSS 416 hinge supports up to 95 pounds. For heavier doors, use multiple hinges spaced according to manufacturer specifications.
3) Is the SOSS 416 handed for left or right swing doors?
The SOSS 416 is non-handed and works with both left-hand and right-hand swing doors. The same hinge can be installed for inswing or outswing applications.
4) What finish options are available for the SOSS 416?
The SOSS 416 comes in multiple finishes including satin stainless steel, bright stainless steel, and oil-rubbed bronze. Check product specifications for available finish options.
5) Where are invisible hinges typically used?
Invisible hinges are ideal for high-end residential doors, commercial applications, and architectural projects where visible hardware disrupts the design. Common uses include entry doors, interior doors, and cabinet applications.
6) What tools are needed to install the SOSS 416?
Installation requires a drill, router or chisel for mortising, measuring tools, and the manufacturer's template. Use the provided template for precise placement and mortise dimensions.
7) How deep must the mortise be cut for the SOSS 416?
Follow the manufacturer's template for exact mortise depth specifications. Precise mortising is critical for proper operation and door alignment with invisible hinges.
8) Can the SOSS 416 be adjusted after installation?
Limited adjustment is possible through the mounting screws. For major adjustments, the mortise may need modification. Proper initial installation reduces the need for later adjustments.
9) What door materials work with the SOSS 416?
The SOSS 416 works with solid wood, engineered wood, and composite doors that meet the minimum thickness requirement. Verify material density can support the mortise without compromising door integrity.
10) Are there other SOSS invisible hinge models for different applications?
SOSS offers multiple invisible hinge models with different weight capacities and dimensions. Browse our hinges section for other SOSS models and invisible hinge options.
11) What maintenance do invisible hinges require?
