Mechanical Lift Hinge Kits for doors weighing up to 3000 lbs

Description:
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.
