Lateral load capacity: 20 tonnes yield with a Safety Factor of 5 providing a Safe Working Load of 4 tonnes (calculated on a mooring line load acting at an angle of 60º to the horizontal).
Fixing Bolts: 4 x 20 mm bolts.  These should be M20 High Strength Bolts to AS 1511-1984 (or equivalent).
Bolts should be cast into concrete with a minimum embedment of 100mm and the concrete should have a 28 day compressive strength of 50 MPa.
Where the concrete is to have a lesser 28 day compressive strength, the embedment length shall be determined by an appropriately qualified Structural Engineer.
