Dome removes for easy cable installation and adjustment. Independant friction and detent are adjustable and removable. 3 stroke, suitable for 33 or 43 cables. Larger center bearing for longer life. T-Handle Control. The A in the part # means that the control comes with one long handle for clutch, and one short handle for throttle. The clutch handle has an adjustable neutral detent. A detent gives you a click so you know where neutral is (without looking at the control). The throttle handle has an adjustable friction so you can get the right feel for your control.
