A guide assembly 10, for one or more door panels in a bi-fold door assembly, comprises a mounting member 12 to mount the assembly to a door pane, the mounting member further including a mount body 18 defining a hollow chamber 20 adjustably receiving a roller body 26 connected to a roller head 28. A rotatable actuator 34 is operably coupled with the roller body 26 wherein rotating the actuator alters the position of the roller body 26 in the hollow chamber to adjust the spacing between the roller head 28 and the mount body 18. Retraction of the roller head allows easier installation into a track after which the roller can be extended. The height adjustment actuator 34 may be threadingly engaged with roller body 26; the actuator may be retained from axial movement. |
