ABSTRACT:
A strap wrench which includes a plurality of gripping pads located on the strap that facilitates tight engagement of the cylindrical object that is used to be located thereabout for the purpose of gripping and turning of the cylindrical object. The strap wrench also includes a brake that provides for securely locking of the position of the strap when it is in its tightly mounted position preventing any loosening movement of the strap. The brake includes a ratcheting mechanism that permits movement of the handle in only one position when the brake is in the locked position. The strap may include a joint assembly which will permit the strap to be separated to be located in conjunction with a cylindrical object and then rejoined.
