The EZ 17 allows you to almost seamlessly transition between the two siding depths available in the EasyTrim® fiber cement system. This profile also provides the protection required on your fiber cement edges and a clean consistent straight line up your wall on all of your inside corners through our connecting ½” tabs extending out to both sides. The EZ 17 also features our patented ez.bump® for full water management, caulk free installation, and Fit & Finish™.
