Pro Aluminum Gutter Guard, Black, 100ft

Waterlock Pro is a professional-tier gutter guard system, manufactured from durable 0.027 in painted aluminum. Its flat, low-profile design slides under the first row of shingles and fastens along the front drip edge with just 3-4 color-matched zip screws per 5-foot section, making installation fast and straightforward. Instead of traditional mesh, Waterlock Pro features a louvered intake design with precision 0.7 mm openings that block leaves, pine needles, seeds, pests, and birds, while 6.7 mm underside intake ports capture high-volume runoff and channel it directly into the gutter during heavy downpours. Double-rib reinforcement along the front and back edges eliminate sharp edges for safer handling. A built-in overlapping strip between sections ensures seamless coverage with no gaps. Compatible with 5", 6", and 7" K-Style, box, and half-round gutter systems, Waterlock Pro works on metal, flat, and shingle roofs.
