The Premier T12 Paper Trimmer measures 13 1/4" x 19 1/2" and can cut pages up to 11 " in total length. The cutting is done on the "medium duty" wooden bed, and this is imprinted with 1/2" grid marks and also with metric and English rulers to help the user obtain the most accurate cuts possible. The board has no-skid feet to prevent sliding during use, which ensures safety and prevents documents or sheets from being ruined from movement during use. Of course, the results of the Premier T12 Paper Trimmer are ensured by the intelligent design of the entire unit. The bed is equipped with a clamp that holds all of the sheets in position to prevent any movement, tearing, or inaccurate cuts. The self-sharpening blades are also meant to provide optimal safety, and can cut 15 sheets at once. The entire length of the cutting arm blade is covered with a finger guard that prevents any risks to those using the device. The Premier T12 Paper Trimmer also features a torsion spring on the arm, which holds the arm open without any risk of falling, while the automatic latch on the blade locks after every cutting motion. The unit is covered by the manufacturer's lifetime limited warranty (including the blade). This gives the use a clear indication of the expectations they can have for this heavy duty trimmer. Weighing in at 7 lbs, it is easily portable, and with the safety features built into the design, it won't create any waste or poor results. The T12 can handle only approximately 15 sheets at one time, but this is supported by the locking clamps and cutting guides built into the unit. With so many patented and trademarked features, this is an innovative resource for a common procedure. It is sure to give great results and for many years into the future.
