Abstract
A clamp mechanism for an adjustable torsion bar of a boat lift. The torsion bar includes square tubes which fit together telescopically to allow the torsion bar length to be adjusted. Each clamp mechanism includes a pair of opposing angle members lined on the inside faces of their flanges with plates which extend along a part of the length of each flange. The angle members are applied in opposition to one another with the inside faces of the flanges directly against the larger tube and the plates against the smaller tube. The angle members are clamped to the tubes by nuts and bolts applied to lugs which project from the angle members.
