For all kinds of masts, tubes... up to 60mm diameter. Includes reduction rings for smaller diameters and a lever to screw the spit into ground. Length 54cm, weight 1.5kgPlease note that when using this spit that the forces at the lower end of the tube or mast can be very high. This can damage the tubing. We recommend to install the mast completely without the spit, and then later set it into the spit when the guy wires are complete.
