The Tucker? Dual Trim Hybrid brush features premium nylon bristles and a dual trim design. The bristles on the outer edge of the brush are slightly longer than the inner bristles. This allows for splaying out of the outer bristles into the corners of the windows while the inner bristles scrub away. The addition of the boar bristle in the middle provides for extra scrubbing power while the nylon outer bristle provides a glide that other boar bristle brushes can't match. This brush features 4 fan jets plumbed to a centralized Tee fitting and a female euro socket making it compatible with nearly every pole on the market today. The addition of the 2nd pair of fan jets allows for a faster, more thorough rinse compared to just 2 fan jets.
