Drop the slug into the mast slot through the
gate using a tool to catch the slug at the desired height. Fix the slug
in place with a single bolt. Offer up the bracket, attaching loosely to
the slug with the second bolt. Now remove and refit the first bolt.
Tighten both bolts. Bracket is then a permanent fixture. Simply attach
Micro Compass clip bracket by means of the 4 stainless nuts and bolts.
The compass may be clipped on and off each
time you sail.
