The 200 mm One Touch winch handle from Lewmar is a practical winch handle that can be operated with one hand. To attach the crank handle to the winch, simply grasp the arm of the crank handle, squeeze it together and open the locking mechanism. To remove it, simply grasp the arm of the crank again, press it together, open the safety mechanism again and pull the crank off. This is real one-handed operation - the second hand remains free to hold the sheet or to secure yourself - an extra plus in safety.
