The Positioning square-D28-175*50*175 (hole-hole) is a heavy-duty locating and supporting accessory designed for D28 3D welding table systems. It is mainly used for 90° angle positioning, vertical alignment, edge limitation, and large workpiece support during welding, fabrication, and assembly operations. The extended structure provides a wider positioning range, making it suitable for applications that require strong support and stable fixture performance.
Featuring a standard D28 hole-hole configuration, this positioning square can be quickly installed on the welding table surface or side panel with quick locking pins. The multiple hole positions allow operators to adjust the installation location according to different workpiece sizes and processing requirements, providing flexible and precise fixture arrangements for complex welding projects.
Manufactured from high-strength steel and processed through CNC precision machining, the Positioning square-D28-175*50*175 (hole-hole) offers accurate dimensions, excellent vertical accuracy, high rigidity, and strong resistance to deformation. Its reinforced structure helps maintain stable positioning during repeated welding operations and supports larger components with reliable performance.
This positioning square can be combined with screw clamps, positioning rulers, locating blocks, support angle irons, and other D28 welding table accessories to create a flexible modular fixture system. It is suitable for metal fabrication workshops, industrial welding production, and custom assembly applications where precise positioning, efficient setup, and dependable support are required.
