ABSTRACT:
This is a device that will provide additional security for individuals who work on extension ladders. It can be fit to any extension ladder and provide a support mechanism so that, if the ladder were ever to shift backward, it would stop the ladder from shifting, thereby protecting the worker. Because of the telescoping nature of the tube, it provides protection and it may be used in a variety of settings.
