发明名称 Method of making a chain binder locking and unlocking tool and product
摘要 A method of making and using a tool for use in locking and unlocking a load-enveloping chain binder, the tool being formed by cutting off the front end of a cylindrical pipe section at an acute angle to provide a leading edge on one side of the front end and an opposite trailing edge. One side of the pipe section is creased rearwardly of both the leading and trailing edges to form an axially sloping, internal, piloting and stop projection against which the handle of the chain binder is received, and while simultaneously squeezing the lateral sides of the pipe pipe section to provide a handle rearwardly of the internal projection.
