The Alliance Rubber Pro Slip-On Grip (8 Pack) is an extremely versatile solution to grip and torque problems at home, in the office or in the field. Use the bands to improve your grip on slippery kitchen utensils or to open jars. Use them to increase torque on screwdrivers or other tools. Use them on the boat to add a grippy surface to items like binoculars to prevent them from going overboard. They're especially useful in cold weather. The Pro Slip-On Grip 8 Pack contains 2 each of the small, medium, large and x-large grips. It offers a wider gripping surface and stronger tensile strength than the standard Universal model.
