Seal-Tite WR Gutters are specifically engineered and tested to meet the requirements of the ANSI/SPRI GT-1 Standard for Gutter Systems Used with Low-Slope Roofs. The gutter system incorporates a 1-in. wide, 2-piece extruded aluminum internal gutter bracket for strength and support. The bracket also reduces telegraphing of the metal due to expansion and contraction of the gutter during temperature changes.
