I have just been following along, is there space for the bottom roller wobble with the arm to the door in between? Mine seems very loose despite tightening the bolt up. Thanks!
How did you pinch the bolt on the lower runner? Cause when I try to do the 13mm bolt up to pinch in the bottom half the bolt tightens up and the lower end does not pull. Causing the roller to lock up instead of being free?? Any ideas please ?
