Its knurled cone and adjustable jaws slip beneath stubborn terminal clamps while a centered screw pad lifts the clamp straight off the battery post. For wiper arms that ride on a tapered spline, the screw pad seats on the top of the splined post enabling a clean, coaxial pull without bending the arm or damaging the paint.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Lisle 54150 remove stuck battery terminals safely?\u003c\/h3\u003e\n\u003cp\u003eThe puller slips its jaws under the cable clamp and the knurled cone secures the clamping point.
