What is the reinforcing cable option ?
The reinforcing cable option is made for installations that have a surface over 25m² and are highly exposed to wind. It is then possible, thanks to this option, to obtain a perfect tension on big sails.
The peripheric reinforcing strap, usually present on the sails, is replaced by a stainless steel cable (4mm diameter). Not only does this solution add more resistance, it also allows you to adjust the cable's tension thanks to two cable-clamps.
The adjustment of the tension to apply to the sail in order to obtain a tightened sail can be made through two ways :
- With the tension system between the ring of the sail's corner and the fixture point (wall or pole).
- With the cable-clamps, allowing you to adjust the length of the cable circling the sail.
Rules of tension:
You note that the sides of the sail are tightened, but curved, and that the sail form a pouch.
Solution: for the sail to be more plane, the length of the cable circling the sail must be shortened.
You note that the sails is tightened in the middle, but a fold is created in the diagonals (or medians), and at the same time the sides aren't tightened.
Solution: The cable's length must bu shortened thanks to the cable-clambs.
You note that the sides of the sail are tightened in a straight line between fixture points, and that the sailsform a pouch.
Solution: You need to extend the length of the cable circling the sail, then tighten the sail on the fixture points (wall of poles). Then, apply rule n°1.
The set up is made progressively, following the aspect of the sail after each adjustment, in order to finally obtain a tightened sail.
