Standard installation is designed for ceilings 107” or taller. If your ceiling is shorter than 107” please
refer to the table below and use the bracket hole height measurements that correspond to your ceiling
height.
Some modified installations will result in a shallower rack depth and linkage arms will be at an angle
when deployed. The linkage arms must be parallel to each other when the rack is installed to allow the
rack to fold correctly.
