The Mission & EDP platform have the ability to be adjusted to level with a leaning tree. The exisiting screw can be a little difficult to turn in cold weather or with gloves on. Our solution is the adjustment knob that allows the hunter to easily use the leverage of a larger knob to easily turn the bolt. The nut recess is designed to be a press fit, there is no need for any kind of bond, glue or epoxy. Simply press the adjustment knob on, and enjoy the luxury of this item.
