Open-ended design makes it easy to cut, seam and splice together banners of any length. Accurately trims up to 4" of material off the edge of a roll, in one continuous cut. Materials are fed through the open side on one end, trimmed, then pulled through the other open side. Line up the edge of the material to the cutting blade and let the trimmer do the work. Clamping strip keeps material secure ensuring clean accurate cuts every time.
