A ladder safety system for secures the upper end of an extension ladder to the roof, eave, or wall of a building. For each ladder rail there is a rail-mountable bracket member that removably mounts onto the rail, a rigid plate member that removably attaches onto the building, and an adjustable strut or arm. Each of the bracket member and the plate member has an eye or ring affixed onto it, and the strut joins the eye member of the bracket member to the eye member of the plate member. The plate member articulates on the strut to permit it to be oriented to attach to any convenient horizontal, vertical or sloping surface.
