To help keep sheets aligned during the cutting process, the base has a permanent 1/2" grid printed with Imperial and metric rulers. A soft-grip ergonomic handle makes for easy-grip cutting. The 24” Premier heavy-duty trimmer includes the following safety features to keep you safe when cutting - a patented automatic blade latch locks with every cutting motion, a finger guard runs the entire length of the blade, and a torsion spring stops the blade from falling during operation. Ideal for small offices, schools, churches and other businesses, the 24” Premier heavy-duty trimmer cuts media up to 24” wide.
