MTL Holdings has expanded their GT-1 tested product line with the introduction of the XL Gutter, the largest GT-1 tested gutter on the market. The XL Gutter is the largest gutter available, up to 14”, that is engineered and tested to meet the requirements of the ANSI/SPRI GT-1 Standard for Gutter Systems Used with Low-Slope Roofs.

This innovative gutter system incorporates a 2”-wide, heavy-gauge aluminum z-bracket and a lower mounting hanger to ensure the system stays secure and prevents wind uplift, no external brackets or wind straps needed. The XL Gutter is available through both Metal-Era® and Hickman Edge Systems.
