Mechanical Lift Hinge Kits for doors weighing up to 3000 lbs

For use on large acoustical doors that require enhanced sealing characteristics by compressing the seal against the frame and threshold. The Lifting action provides ½" rise in 180 degrees of door rotation via a unique high lead power screw and nut design that will take higher loads, wear less and operate easier than conventional cam-lift hinges. All wear surfaces are lubricated and sealed from the environment. Can also be used in self-closing applications where the minimum door weight is 150 lbs.

A (3)* hinge kit comprised of: (1) LIFTU hinge located at the center of the door that supports the weight and provides the lifting action; (2) Series W radial support hinges, properly spaced take the radial load. Refer to the Engineering Section on how to calculate radial load based on hinge spacing or contact the Engineering Department.
