Calibrates and opens the channel rail to the channel diameter
Use the keder spike to bring bent keder strips back into shape. Insert a mandrel of the appropriate thickness (different thickness 7 and 9 mm at each end) and hammer through the keder strip with light blows using a camping hammer.
If the keder strip is widened, the keder spike can also be used for the opposite. Simply insert it and then tap on the outside of the strip with the hammer, the keder spike then serves as a template on the inside.
TIP: Dirt can also be the reason for problems when pulling in the piping rail. Simply clean the channel rail with white spirit or thinner and then spray with silicone-based sliding sprays.
