With the galvanized heart-shaped thimble, the loops used for setting up the shade sails are protected from wear and rubbing. Also, the thimble helps to facilitate the sliding of bindings and ropes through these loops. Select the appropriate number that is necessary for your model. This number is indicated during the selection of the shade cloth size. To cover a diagonally reinforced M2 shade sail, 4 pieces are required, while for an equally reinforced M3 product, the number of pieces will vary between 10-20, bearing in mind the size of the shade sail. The order of 4 heart-shaped thimbles for the M2 diagonal reinforced shade cloth includes a kit with 4 thimbles, 8 plastic cable ties and some rope to cover the cable tie, together with an instruction manual. It is also possible to order even one piece.
