Fitting Procedure
- Remove the hook from the plate and give the plate a corrosion protection coat.
- Place the plate centrally on the front line of the mast at the correct level, shorter side down. Using the plate as a jig, drill for the pop rivets (Ø 4,9 mm for O:22, Ø 6.5 mm for O:35 and O:50).
- Fit the 4/6 rivets.
- Through the plate, drill the mast wall at the upper and lower edge of the oval holes (Ø 8,0 mm for O:22, Ø 10 mm for O:35 and O:50).
- Saw out the mast wall between the holes along the straight parts of the oval; file the edges.
- Fit the hook into the slot, threaded-hole end first into the upper part of the slot.
- Remove remaining rivet mandrels.
- Feed the stay's terminal eye onto the hook and refit the hook as in step 6.
- Fix the hook with the screw and washer.
The O-ring stops the hook being lost inside the mast.
