Thanks for all the info. What a friendly helpful bunch . As my garage door is 7'6" then I should be ok with no rear cover or hoops , thanks for that Degby . David I'm going to be in Inverness on Friday 6th November and most of Saturday so if it's ok with you I would love to see the cckw close up , not just one but two !! I would really appreciate that as it will tell me all I need to know
