The Adjustable Arm set up is extremely useful for large offset situations where just installing longer pivot bolts and spacers not only weakens the hinge, but renders the hinge to be non NFPA 96 compliant because the service hold open pin will not reach from the cam to the upper hinge arm. This solution is best used when offsets are in excess of 3 inches. The adjustable arm solution moves the offset to the lower mounting bolts, thereby keeping the functionality of the service hold open retainer. The twin lower arm bolts are extended and spacers are added to them, rather than on a single pivot bolt. On extreme offsets we will add a third lower arm bolt in a triangulated pattern. This adds the strength of an additional bolt, as well as limits the amount of twisting flex that would normally happen. This solution can be used on both the Super Hinge and Quick-Fit Super Hinge models.
