These bundles of thatch are used to seal the hip rafters of thatched gazebos. They are spaced at approx. 400-450mm spacing with 2 bundles attached to a 70 x 35mm length of timber which is screwed to the hip rafter. 

These bundles need to be zip tied individually and then with a long zip tie, arrange 3 bundles over the corner and tie to the timber.
