Edson’s new teak Pro-Series PowerKnob makes a handsome addition to any helm, and makes maneuvering in tight quarters or backing down a breeze. The teak knob is built to the same exacting standards as Edson’s stainless-steel knob, and features twin races of fast-action Delrin bearings for smooth operation. The knob straps easily to any stainless or aluminum wheel rim with a diameter of from 5¿¿8″ to 1 1¿¿8″, and even comes with its own allen wrench to simplify installation. Suggested retail price of the teak knob is $125, while the stainless knob sells for $99. Edson Intl., New Bedford, MA; (508) 995-9711; www.edsonintl.com.
