This side rafter bracket is generally used on properties where there is no fascia board at the eaves (often referred to as open eaves).The rafter bracket is screwed onto the side of the foot of the rafter at the eaves. A standard fascia bracket is then attached to the vertical section of the rafter arm using the small nut and bolt supplied.The fascia bracket can then be adjusted up or down to ensure that the correct fall is achieved on the gutter.
