Case 580 coupler

These couplers have been the most technically challenging for us to make. Note how the sides have to be precisely formed to fit the typical Case bucket hangers. Getting this form on a 20 mm side plate, which holds its shape after multi seam welding is not an easy task. Furthermore the liner bosses in the couplers have to be perfectly aligned for a good fit. We consider making such couplers a testimony to our precision fabrication and high skill levels of our colleagues.
