This mitre box is a simple mechanical means of preparing a shortened length of 300, 220, 100 or 100 x 50mm duct for connection to another standard part. e.g. elbow, cross connector, etc. The mitre box ensures that a true 90-degree cut is achieved with a panel saw (Part No: 100 x 060) on each of these duct sizes.
