How to Measure

Projection is the measurement from your point of attachment out to the very outside of the gutter.

Width will be the distance along the point of attachment.

Need help with your measurements?

Simply measure the area you would like to cover, taking your existing overhang into consideration, or just measure the area and let us know what your overhang is and GL Aluminum will do the rest. We would be happy to get back to you with a quote as soon as possible, including approximate shipping costs.

GL Aluminum recommends approximately 1' of overhang around the perimeter of your deck or cement pad to help protect it from the elements.

To find your post height deduct ½” per foot from your point of attachment, less another 4” for I beam height, then order them a little longer, they are the one component that you should trim on site.

Please inform us if you plan to erect a free-standing structure or a peaked cover; extra posts and beam will be necessary.

For custom designs or angles, please send us photos or a drawing via email to carol . and we will guide you through the ordering and installation process.
