Measuring your commercial grade gutters is the fastest way to gauge the size you need. The 7-Inch GutterBrush is designed for gutters of that size, but it can be placed in a larger gutter and still prevent clogging. The 8-Inch GutterBrush also solves clogs and keeps water flowing in a larger 9-inch custom gutter.

You want to fill 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 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.

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 a gutter brush 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 3 different samples in the gutter as follows. 

1)  Buy our commercial sizing sample pack ( SKU smp-com ) which contains 6" length samples of all 3 of our largest commercial sizes: for $ 9.95

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   Be careful to purchase the commercial sizing samples and not the residential.   Click here to go to Sizing Samples

3)  Another option is to print and use our sizing chart to (scissors) cut out circles that match the diameter of each of our brushes, set these circles into the gutter to determine the best fit. Click here to go to the sizing chart
