135 Degree Gutter Angles, or 45 angles as they sometimes referred to as, are generally used when the guttering and fascia runs above a bay window. As the system is symmetrical, both internal and external corners use the same fitting - there is no difference.You should always support any gutter angle by positioning a fascia bracket within 150mm on both sides of the angle. This will prevent the fitting from sagging when it is weighed down by water or snow.
This product would be ideal for homeowners looking to install rain gutters, especially those with a sloping roof pitch, requiring a bend of 135 degrees.
