This invention relates to a ladder safety fastening device with extendable telescoping arms for securing a ladder to such things as eves troughs, industrial joist, fascias and the stabilization of ladders for the mounting and dismounting off of a roof.
Ladders perform an invaluable function in the lives of everyday workers, homeowners, trades people and maintenance crews to name a few.
Insofar as there functionality goes, technology has given us both the designs and the materials needed to produce some of the strongest ladders available. Although rugged construction and design of ladders have improved over the years, safety has not, that is the primary goal of this device.
This invention relates to a ladder add-on which in particular focuses on the safety of the user.
It is common in extension ladder usage to have someone hold the ladder at the base or tie the ladder off at some points to avoid incidents of ladder slip out.
Where-by resorting to this device, once fastened to a secure location prevents any chance of ladder slip out and provides fall protection as well.
