Tightening tool
A rod tightening tool includes an elongated member, a clamping assembly and a wrench attachment end. The elongated member has a semi-hollow interior and defines an opening at one end thereof providing access to the semi-hollow interior. The elongated member has a slot formed along a portion thereof that extends to the semi-hollow interior. The clamping assembly has a first member and a second member. The first member is installed for sliding movement along an exterior surface of the elongated member. The second member is installed to the first member such that the first and second members clamp to the elongated member. The wrench attachment end is fixedly attached to the elongated member.
