Infinite Adjustability (Holes vs. Slots): Many of our 3D squares feature a combination of standard boreholes and elongated slots. This allows for precise micro-adjustments before locking the block down with a clamping bolt.
Multi-Functional Geometry: Use flat rules as straight backstops (fences), 3D squares for vertical 90-degree clamping, and T-squares for specialized structural node locating.

Create a Solid Fence: Use two Fast Clamping Bolts to secure a 1000mm Flat Locating Rule across your table. This creates an immovable X-axis straight edge to push your main structural beams against.
The Perfect Corner: Place a Flat Square at the corner intersection of two beams. Clamp the beams directly into the square to guarantee a perfect 90° joint before applying your tack welds.
Vertical Support: Use a slotted 3D Positioning Square to hold up a vertical post. Slide the square along the slot to achieve the exact millimeter placement before fully tightening the bolt.
