Abstract: The invention provides a barbeque lid adjustment device including a shaft member attached to a movable lid of a barbeque grill or cooker and a rotatable elongate member. The rotatable elongate member includes an engagement section at one end for engaging a cooking bin of the barbeque grill or cooker and a handle section at a distal end for rotating the elongate member about an axis coincident with the shaft member. The elongate member is rotatably attached to the shaft member between the engagement section and the handle section and enables a user to adjust a lid of a barbeque grill with one hand to various partially open positions for controlled cooking.
