Description
D400 and D400 Lite are a socket type fit into the chosen mount tower tubing.
The fit between the D400/ D400 Lite yaw shaft and the internal diameter of the mount tower is achieved using a tower liner.
As standard the tower liner will fit a mount tower tube with a 42 mm bore.
Custom tower liners machined to suit other tower tube sizes are available on request.
