Mast sections
E-sections, D-sections and R-sections
Our older types of mast sections are no longer in production. But we stock a full range of spare parts
and accessories for these masts. Please note that
the mast section is always the key for correctly
identifying the parts you are looking for.
170 -1233. Mast section measurements are given as follows:Major diameter/Minor diameter (i.e. 170/115).
Take note of the mast shape. This will help identi-
fication and the use of correct measurements.
The major diameter of the mast can usually be
found in the number engraved at the mast heel.
