buttons B on the opposite side of the same leech. Choose for 1 or 2 or both together.

1. Buttons installation with sewing system

Remove the liner from the button (A) and glue it as close as possible to the edge of the 

sail, without overlapping it on the colored luff tape.

Repeat the operation with the button B, on the other side of the sail, making sure that 

the holes of the buttons A and B coincide; to facilitate the operation, after having glued 

in button A, insert two needles in two opposite holes of the button, turn the sail and 

insert the button B in the two protruding needles and glue.

Sew buttons A and B using the appropriate needle and thread.

2. Buttons installation with screw system

Without removing the liner, place the button A in the desired area and mark the position 

of the hole with a pencil or pen. (no marker pen because the ink expands a lot).

Hole the sail, or make 2 cross-cuts of 3mm with center the sign made.

After removing the liner of button B, position the button and insert the screw that will 

protrude on the other side of the sail where you will apply, removed the liner, button A.

Insert the nut in the special cavity of button A and screw it in place.

Threadlocker between the screw and nut is recommended to prevent loosening.

By choosing this method, the use of sewing is your discretion.

Repeat the operation for all buttons.
