Attachment of Spreader.
Primary Pin: Fit down through the bracket’s primary hole and the Fwd or Aft
spreader hole as required.

and through D to E.
Please see the table on the previous page for the specific positions.
Spreader Ends
Spreader End Cap:
The spreader end cap incorporates two shroud wire slots to give a tight grip on either 2.5 or 3mm wire. The
sizes are identified on the front face of the end cap (See diagram above). To find which wire slot you
require for your mast, please see the table below.
The end cap can also be rotated so that the shroud can be positioned at either the forward or aft position of
the spreader end (see diagram above). To find out which position is required for your mast, please see the
table below.
To attach the shroud, slacken the end screw, rotate the end clamp if necessary, then insert the shroud.
Ensure that the shroud is tensioned between T-Terminal and spreader tip, then tighten the screw firmly.
This method “locks in” the dihedral angle.
Length Adjustment:
The position is described by the number of adjustment holes visible (e.g. In the diagram above there are 1
½ holes visible).
Please see the table below for your class specific positions.
Security
All clevis pins must be fitted with the flat head on top, and locked with a split ring. Tape all split rings, pins
and the outboard end of the spreader extrusion. This will reduce chafe on the mainsail and prevent flailing
sails/halyards becoming damaged.
Self-amalgamating tape is best, but pvc electrical tape is an adequate alternative.
