The Optiparts shim plate is designed to provide a flat, stable mounting surface for tiller extension bases onto round tubing. This plastic adapter is engineered to fit tubes ranging from 25 mm to 32 mm in diameter. By contouring to the round shape of the tiller or tube, it eliminates play and ensures a firm, rock-solid attachment for your tiller extension joint.
Contoured Fit for Round Tubes: Perfect for installing tiller extension universal joints on tubes from Ø 25 mm up to 32 mm.
Prevents Wear & Movement: Distributes pressure evenly to prevent slipping, loose play, or damage to the tiller tube.
Marine-Grade Plastic: Built from tough, UV-stabilized composite plastic for long-lasting performance in marine environments.
Easy Mounting: Fits seamlessly beneath standard tiller extension mounting bases.
