Measuring your commercial grade gutters is the fastest way to determine the brush diameter size you need. The 7-Inch GutterBrush has an actual diameter of 6.5 inches and is designed for 7 inch gutters. The 8-Inch GutterBrush also solves clogs and keeps water flowing in a larger 8 inch or even 9 inch gutters. GutterBrush will effectively solve gutter clogging even if it is slightly undersized for the gutter.
GutterBrush Brush Gutter Guard Fit Criteria
To fit your large or other size gutter, you want to choose the GutterBrush diameter that fills the width of the gutter as fully as possible without overly compressing the bristles. In some cases it may be desirable for the brush to have a crowned or raised bristle profile, which is slightly higher than the outer edge of the gutter. This allows the wind to purge leaves from the brush. The raised profile is not always necessary and not possible in many metal building gutters known as Sculpted Eave Gutters.
When a raised profile of the brush is not desirable or possible:
1) Some commercial buildings have a raised gutter outer edge that is actually higher than the roof drip edge. Having the GutterBrush profile raised higher than the roof drip edge is usually not desirable.
2) Many gutter styles have a gutter width that is different than the gutter depth. If a gutter is taller than it is wide, a raised profile would not be possible.
FITTING - Get Sizing Samples
Getting the right size: To decide which GutterBrush size will work best inside your gutter, you can measure the inside dimensions to determine which GutterBrush product will best fill your gutter (without overly compressing the bristles.) Such can be a challenge because many gutters have complicated shapes with multiple angles and corners. The best way to be sure you purchase the best size is to set multiple different sample sizes into the gutter and compare the fit, as follows.
1) Buy our commercial sizing sample pack ( SKU smp-all ) which contains 18" length samples of 5 GutterBrush diameter sizes:
2) Once received, set each sample in the gutter and decide which size best fills the width of the gutter without overly compressing the bristles.
3) Another option is to print and use our sizing chart to (scissors) cut out circles that match the diameter of each of our Gutterbrushes, set these circles into the gutter to determine the best fit. Click here to go to the sizing chart
