ALPHA 28 Welding Tables from Strong Hand Tools are for fast modular fixturing for metal fabrication, assembly, and welding. Based on 28mm holes with 100mm spacing, there are various sizes available that can be re-configured or joined together to fit any size requirement. The modular plate design allows for plates to be offset, removed, flipped, or replaced as needed. A Nitride finish helps reduce corrosion and eliminate sticking of weld spatter.
