Strong and durable replacement trimming mat for the Leitz Precision A4+ Office Trimmer (product code 90270000). The mat is designed to sit directly under the trimming path to protect the trimmer rotary blade and ensure accurate trimming or perforating every time. Features 4 trimming positions (2 on each side) to get maximum use from the trimming mat, when the blade does not trim cleanly, simply rotate the mat or flip it over to the second trimming surface. When all four positions have been completely worn it can be replaced with a new trimming mat so you have peace of mind that your paper trimmer will provide accurate trimming for many years.
