The retaining portion of the structure is configured to receive a first section 118 of a workpiece 104 such that a second section 120 of the workpiece is positioned at an angle 121 relative to the magnetic portion of the structure. The magnetic portion of the structure is positioned at a first side 108 of the workpiece. The locking magnet is configured to exert an attractive force 144 that causes the magnetic portion of the structure to move towards the second section of the workpiece when the locking magnet is positioned at a second side 110 of the workpiece.
