What trial and angular extras are available?
Try 45° squares | ||
| There are several 45° squares on the stock, making them a trial square. It can be found either at the base or at the end of the blade of the stock. Instead of a fully square stock, one corner is missing, forming a 45° angle; this does not interfere with the correctness of the angles. | |
 | The rough and corner squares are used in the same way, only the orientation required to represent the corners changes. | |
Spirit Level Flasks | ||
 | A vial similar to those found at the spirit level can be found in the stock of several trial angles; this allows the tool to check angles and horizontality. The tool can be installed to check the horizontal and vertical workpiece. | |
Scales | ||
 | Many trial corner squares have a scale along the blade; this often means the rule is not needed. Measurements can be in inches on one side and millimeters on the other, or with just one type. The scale is useful for setting the distance for the corner cut. | |
adjustable squares | ||
 | The fitting and corner squares are adjustable, meaning that the stock and blade are hinged, allowing the tool to not only measure different angles, but also fold up for storage. Some of the adjustable angle brackets will snap into selected angle positions and some will scale down the stock with angle positions. | |
Adjustable and fixed squares | ||
 | The advantage of adjustable squares is that they can measure/mark/check multiple angles. However, the accuracy of an adjustable square is not as reliable as a fixed one due to movement (they can fail). | |
