Adjustment-PrincipleManfred Frank hinges feature an ingenious and unique principle, which is protected by worldwide patents. Panel alignment is achieved by altering the distance between pivot points, which in turn varies the hinge geometry. There is no need for any lifting or support equipment. With only a spanner or a hex ball nose key (depending on the hinge model), a single person can easily align even the largest door panels instantly and precisely under full load.
