The Spinlock EJB Style Tiller Extension - Spinflex Joint is designed for use with both 600mm and 900mm extensions. Its UV resistant and extra tough Spinflex joint allows for 360 degree control, swiveling freely through the full range. This unique joint is pre-moulded at a 30 degree angle to reduce bending stress during use and at rest, preventing early failures commonly found in vertically moulded joints. With the Spinflex joint, the tiller can be securely held in a helming position 30 degrees above horizontal, providing a choice of grip positions with the triple wave handle. This extension offers a precise and responsive helm control, and can easily be retrofitted from other products to upgrade to the Spinlock EA or EJ models.
