Lass Enterprises, Inc.'s Dura Grip IV is an all purpose strap wrench that quickly and easily adjusts to fit any size or shape object up to 10 inches in diameter. The Dura Grip IV automatically locks the strap's position when torque is applied using the 8 1/2" handle - thus there is no need for the user to hold the strap while using the wrench. Manufactured of PVC (handle) and reinforced neoprene (strap), the Dura Grip IV is ideal for use in severe environments. The strap grips the object without scratching or marring its surface while the 8 1/2" handle allows for the application of plenty of torque to either loosen or tighten the object.
