40mm x 1.5mtr Interlocking Aerial Mast Sections
They have 3 splines that when they are fitted together, they cannot twist.
Once assembled they should be considered permanent, as they lock together
and are difficult to separate,
We recommend a maximum of three fitted together in one installation
Interlocking Mast Sections are the perfect solution
for sending long aerial masts by carrier
and reduces the carriage costs
