How To Install Your Gutter Guard Samples: Set them into the gutter to compare brush gutter guard sizes. The brush should fill the width of the gutter as best as possible without overly compressing the bristles. A raised or "crowned" profile is desirable, however with a high outer gutter edge, a raised profile is not possible and not necessary for gutter clog protection.
