1 pack = 1 corner
(eg if you are buying a rectangular sunshade you need to purchase 4 packs of hardware)
Choose between the fittings and the fitting kit to measure the space available between the corner of the sun visor and the anchorage point. This space is less than 25 cm, it is also sufficient for the packets to be stretched (without steel wire). If the space is larger than 25 cm, the remaining space is required to add a steel wrap, so it is necessary to choose the larger steel wadding package.
A worm system is sufficient to put a corner of the chosen sunshade.
