Select options Rods & Nuts for KWM Gutter Brackets $1.75 – $4.25 Gutter Brackets hung from the roof with a rod are called hanger units. Existing roofs, with a standard shingle installation, will have the rod placed over the first course of shingles and the flat part of the rod secured with 1½” screws under the second row of shingles. A new roof installation allows the rods to be placed under the roofing material, especially important for tile or slate roofs. The 11″ rods are available in stainless steel and aluminum. Stainless rods are shipped straight and need to be bent onsite, while aluminum rods can be bent by hand. A rod bending tool can be rented to consistently bend the stainless steel rods to the same angle. The rod bender deposit is refundable upon the return of the tool. For coastal locations we recommend using our marine stainless steel rods. Rods are shipped with the 2 stainless steel nuts required.
