Alu-Rex’s flagship product is covered by the most extensive warranty in the industry: a lifetime warranty on materials, durability, and clog-free performance. DoublePro® is the only gutter guard whose clog-free warranty covers pine areas.

The double membrane keeps debris from getting inside the gutter. The offset holes make it the perfect filter, allowing water to drain freely while blocking pine needles and leaves without ever getting clogged. The suction created by the two membranes makes it possible to drain three times more water than ever recorded in the heaviest storms. The inner membrane draws water through the wider holes.
