Thx guys, I should declare I was a fitter in a previous life. I have tensioned the odd roller door and my panel lift.
I would happily pay someone but the guy I had lined up I postponed and he said call me when ready, 4 days later I call and he says Iam booked up till Tuesday and then gone for a month! The other local guy ^*##ed my 2 doors 12 yrs ago and the reason I have previous experience.
Mr Horsepower thanks, I have read those and the steel-line install destructions. I may call if okay. I just have a few questions to be sure.
