Customer Reviews
Rated 4.7/5 based on 52 reviews
Ordered the 5" aluminum single units for a repair job. Perfect fit on standard K-style gutters. Fast shipping and well packaged.
Bought a 500-box of 4-1/2" aluminum for a commercial project. Great bulk pricing, solid quality, and the order arrived on time.
Used the 6" copper finish ferrules on a high-end residential project. Clients loved the look. GutterAll had the best price I found anywhere.
Frequently Asked Questions
What size ferrule do I need for my K-style gutters?
Choose 4-1/2" ferrules for standard residential K-style gutters, 5" ferrules for enhanced capacity commercial applications, and 6" ferrules for maximum capacity industrial applications.
