ABSTRACT:
A strap wrench made up of a semi-rigid, form retaining, planar strip wrap around. This wrap around is formed into a shape retaining loop, the opening of the loop being readily adjustable. Because of the semi-rigid, form retaining characteristics of the wrap around strip, the loop will retain its shape and size as it is moved about and positioned over an object to be rotated. A simple squeeze of the strip will conform the size of the loop to the outer diameter of the object to be rotated. A flexible pull cord is attached to the fore end of the semi-rigid, form retaining strip and wrapped about the strip prior to or as the strip is placed about the object to be rotated. A simple straight line pull on the flexible cord exerts a force which acts along a line which is tangent to the object to be rotated and which acts at a distance removed from the axis of that object.
