Directions
After determining the weight and width of the door, draw a straight line through the door width and weight to line
“A", as indicated in the example. Continue with a horizontal line sideways from the point of intersection with line
“A" until the door thickness is reached. Use the number of hinges and the model number indicated on this line.
The nomograph below has been developed to assist you in determining the correct size and number of hinges for your installation.
If the information you need is off the chart, consult the factory.
The general rule used to determine the number of hinges is:
Every door should be provided with at least one hinge for
every 30" inheight or portion thereof; however,morehinges
may be required per chart.
For example, a 90" door needs three hinges and a 91" door needs four.
Example
A wood door 30" wide, 200 lbs., with a thickness of
1-3⁄ 4" will require four #218 SOSS Invisible Hinges.
The red line shows how the sizing and selection
were determined from the nomograph.
