Hold stock from the outside, leaving clearance for inside welds, or hold stock from the inside for outside welds. Hold and position sheet metal, round pipes, square, angled or flat stock. The Inside / Outside Angle Magnets are constructed from two independent rectangular magnets for consistent, undiminished magnetic force when both sides are attached to work-pieces. Use mounting holes to link two magnets together for use as fixture elements. Use hex hole on magnet for breakaway leverage.
