Manfred 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 an hex ballnose key (depending on the hinge model). A single person can easily align even the largest door panels instantly and precisely under full load.
Each plane of adjustment has its own specific mechanism.
The turnbuckle linkages feature a left and right handed thread, which are used to adjust the sideways and compression locations of the hinge. Turnbuckles are adjusted using a simple 11mm Open Ended Spanner.
Cap Screw Linkages
Cap screw linkages are used in the place of turnbuckles where accessibility is restrictive and spanners are inappropriate. The standard tool required is a 5mm Hex Ballnose Allen Key (preferably in a T Bar configuration).
1. Once mounted, the first adjustment to make is to set the correct height position. Unscrew the uppermost set screw to allow the height adjustment arm to move. Then turn the lower set screw until the desired height is reached. Finally, turn the upper set screw down to hold the height adjuster arm in place.
2. The next step is to manipulate the sideways and compression linkages until the panel is aligned. When adjusting the length of a linkage there might be a slight crossover effect on the other linkage. For example when adjusting the panel compression it might be necessary to compensate for the crossover effect on the sideways linkage.
Thus, aligning the panel is a quick and simple process of refinement.
Manfred Frank hinges are built to last. The patented principle incorporating self locking adjustment mechanisms ensures permanent perfect panel alignment. Manfred Frank offers a GUARANTEE -NO LOSS OF ADJUSTMENT for the life of the hinge.
Any future alignment changes due to building or frame structure settling will only require two basic tools and just moments of a single person’s time. No lifting or supporting equipment is needed.
