Measure the total length of all your gutters to determine the amount of GutterBrush you need. For the best performance we recommend that you completely fill your gutters end to end with GutterBrush.
Select a combination of boxes that add up to the amount of GutterBrush you need. If our lengths do not match up exactly to your measurement, we suggest rounding up to the next length to be sure you are not short.
GutterBrush comes in a combination of 3 foot and 18 inch lengths.
