Edson ComfortGrip™ PowerKnob - Fits All Wheel Rims from 5/8" to 1-1/8" Diameter - Edson Product #-969ST-18CG Edson�s latest addition to their popular PowerKnob line of steering wheel knobs is the new ComfortGrip™ model, featuring a rubber grip insert for the ultimate in fingertip control. The rubber insert is soft to the touch with a tactile, non-slip finish and deep fingergrips for a secure hold. Made of Santoprene®, it is highly durable, and resistent to sunlight, saltwater, oils and perspiration, making it an ideal material for the demands of the harsh marine environment. The ComfortGrip PowerKnob body is built of marine-grade stainless with precision milled and highly polished surfaces. Because of the highest quality construction and materials, the knob is covered by Edson�s 25 year warranty. Edson engineers created the PowerKnobs to be super-smooth in the harshest of environments by incorporating twin races of captive Delrin® ball bearings and precision milled stainless bearing surfaces. Edson PowerKnobs can be mounted to nearly any wheel by using either a simple, clamp-on design that minimizes installation time (tools included!) or by bolting directly onto solid-rimmed wheels with an included stainless bolt. On the water, Edson PowerKnobs are a real benefit to the boater. They aid in maneuvering in tight quarters and allow fast action when backing down on a fish or into a slip. The Edson PowerKnob can improve handling on any type of boat, from a flats boat, center console, ski boat or runabout to a sportfish, motoryacht or trawler. And when combined with Edson�s classic ComfortGrip PowerWheel™ featuring the same tactile rubber finger grips on the underside of the wheel rim, the boatowner can enjoy the best in both comfort, strength and elegance. The knobs are available through Edson�s network of Authorized Dealers, marine catalogs or factory direct.
