E/Z Strips are an incredibly easy way to adjust the width of the shutter set without having to use a saw. -Each E/Z Strip is 1/8" thick. To reduce the width of the set by 1/8", simply pry off an E/Z Strip using your finger or a screwdriver. Each subsequent strip reduces the width by 1/8" more. -If you take off too many E/Z Strips, simply snap as many as necessary back on. -E/Z Strips make it easier than ever to install shutters on the inside of the window. -They can also be used for outside mounts when more depth clearance is required.
