Clip it through your harness waist band first, tape it so that it doesn’t move and then the screws will rack in the end where the gate opens. The ice screw hanger pushes against the gate of the karabiner, opening it and allowing you to hook the screw onto the karabiner with one gloved hand.
Much better is to make your own Simond style double rack:
