SOSS Door Hardware Standard Hinge Sizing Chart 2018

Choosing the Right Hinge and the Right Number of Hinges

For your convenience, an interactive, easy to use hinge sizing calculator is available on our website, www.soss.com.

If the information you need is not on the online calculator or this chart, consult the factory.

To obtain the best performance from SOSS Invisible Hinges, it is recommended that the largest hinge model be used for the material thickness of the door.

Every door should be provided with at least one hinge for every 30 inches in height or portion thereof; however, more hinges may be required per chart below.

Door Width

For example, a 90" door needs three hinges and a 91" door needs four.

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.

To use this chart as a working guide, we suggest that you photocopy this page.
