LeafBlaster Pro® is a stainless steel micro-mesh keeps out leaves, pine needles, and roof grit. The micro-mesh combined with an aluminum extruded frame provide the perfect amount of strength and flexibility for the ultimate gutter protection that won’t warp, crack, or rust, so you can expect protection season after season. The Z-bend technology lifts debris off the gutter guard so that it can blow off in the wind and ensures superior water flow, even in severe downpours. LeafBlaster Pro® is only to be installed by licensed contractors.
