How many hinges do you need? Use the Torsion Calculator to help determine your ideal hinge combination. For best results, choose a combination of hinges that provides as close to your lid's required support as possible. A simple formula can also be used to determine suggested hinge combinations: (Lid Depth x Lid Weight in Pounds) / 2 = Suggested Inch-Pounds of Support. As an example, if the formula returns a value of 125 inch-pounds, suggest using two 60 inch-pound hinges. If three or more hinges are required, the support capacity of the outside hinges must be the same. It is also suggested that hinge configuration is symmetrical.
- Step 1: Attach hinge to lid with 3/4" screws (included). For the lid to be flush with the back of the box, the top of the hinge should be 1-9/16'' from the back edge of the lid. To create an overlay, increase the 1-9/16'' dimension by the desired amount of overhang. NOTE: Our Lid-Stay Torsion Hinge JIG IT (#23625, sold separately) lets you attach the hinge to the lid in seconds, and requires no measuring. Ideal for both flush and overlay applications.
- Step 2: With all hinges attached to the lid, position the lid on the back of the box. Complete the installation using 1'' and 3/4'' screws.
