ABSTRACT:
A tool used in the construction of frames includes multiple clamps that are used to secure frame members at precise angles and orientations for welding. The tool includes a vertical support post upon which is mounted a table. First and second clamps are pivotably mounted to the table and allow two frame members to be secured in contact with one another and parallel to the table at a precise angle. A column extends upwardly from the table. At the upper end of this column is a support arm which is held parallel to the table by the column. A third clamp is mounted on the distal end of this support arm. This third clamp can be used to position a vertical or diagonal member in contact with the frame members held by the first and second clamps for welding. Additionally, the tool includes first and second attachments which can be used to secure vertical or diagonal members to the frame.
