Edson’s Standard Quadrants are cast Manganese Bronze or 356-T6 heat-treated Aluminum.

Available in 8” through 24” radius sizes, the Edson Quadrant is effective whether mounted fore or aft of the rudderpost.
The quadrants are machined to accept #618 Take-Up Eyes, making installation and adjustment of steering cables easy.
All bearing surfaces are machined, a positive fit is assured by the Edson Capped Hub, and the clamping action allows installation without having to remove the rudder.

NOTE: All Quadrants must be mechanically affixed to rudderpost.
