Conventional column connection solutions often don't work for metal columns due to different material properties and their larger outer diameter. The following solution can be used to connect 2 metal columns:

• 0.53 mm to 0.25 mm (you have to order: 1x 980-06597, 1x 980-01428, 1x 980-05636)
• 0.32 mm to 0.25 mm (you have to order: 1x 980-06597, 1x 980-01428, 1x 980-05636)
• 0.25 mm to 0.25 mm (you have to order: 1x 980-06597, 2x 980-01428)
