Dovetail shapes or wedge shaped joints, reach far back into the history of mankind. Even the Egyptians used perfect 'dovetailed' joints in the pyramids.
The Roman Empire constructed magnificent buildings and traversed wide spanned archways with massive stone blocks in dovetail form and erected them without any additional bonding. Many can still be admired today throughout Europe and the Middle East and analysis of the remains, suggest that they were of structurally sound construction.
The company Hoffmann Engineering - the inventor of the Hoffmann- Key - has perfected this jointing process and offers this multi-functional jointing method for endless possibilities and opportunities in industry. The Hoffmann Double Dovetail Key is ideal for secure and fast connection of two wooden parts.
