The assembly of the spreaders to the mast is produced by the thru bars, plates with rivets and clevis pins. The new fittings include only aluminium thru bars. You will also find the references of the former stainless steel fittings.
⊕ The assembly allows an angulation from 0 up to 30 degrees and
> a 0° dihedral for catamarans
> up to 10° dihedral (to the top) for monohulls

> Reference determination of the thru bar according to the angle & dihedral, + type of spreader (BF2/BF3/BF4/BF5).
> standard : 0° angle / 5° dihedral. Others : angle = xx° / Dihedral = Y°
> Covers : according to the type of spreader
> Plates : according to the type of spreader + mast section
