Abstract: A magnetic clamp for attaching to a ferromagnetic mounting surface to provide a securement location on the mounting surface is disclosed. The magnetic clamp includes a base member formed of substantially non-ferrous material, wherein the base member is operable to flex to accommodate for changes in curvature or irregularities of the mounting surface and at least one of magnet element arranged on the flexible base member for attaching the base member to the mounting surface. The magnetic clamp further includes a securement means as well as manually actuated release means to remove the magnetic clamp from the mounting surface.

Abstract: A magnetic clamp attachment assembly for securing a ladder arrangement to a ferromagnetic surface is disclosed where the ladder arrangement comprises two spaced apart side members and at least one rung extending between the side members. The magnetic clamp attachment assembly includes a spacer member sized and configured to extend over the spaced apart side members of the ladder arrangement and magnetic attachment means for attaching the spacer member and securing the ladder arrangement to the ferromagnetic surface.
