The bottom bracket measures 1200mm long, and it can lift to a maximum height of 930mm. They are 5.7 kg each.
When replacing, it is best to replace opposite lifters at the same time, to prevent undue stress which will bend the arms.
These are stronger than the tubular arms.
CARE - when fitting, insure they are replaced in the same direction as they were i.e. if the fixed corner is on the right, replace it with the fixed corner on the right.
This will vary for each side.
The enlargement shows the bracket closed. The image shows the mounting holes in the vertical face, and there are also holes in the horizontal faces for alternate mounting.
When this is in the fully down position the distance from fixed pivot point to the centre of the roller in the channel is 1120mm. When the roof is at 800mm high the distance is 820mm, when the roof is at its maximum height of 930mm, the distance is 620mm.
