Abstract: A multipurpose ladder attachment comprises a bracket plate, a pair of U-bolts, and nuts for attaching the bracket plates to a ladder. Upper apertures in the bracket plate receive the threaded ends of the upper U-bolt, and lower apertures in the bracket plate receive the threaded ends of the lower U-bolt. At least two of these attachments are typically used in tandem on a ladder. Each bracket plate has a tapered slot extending downward from the upper edge that terminates in a hole. The holes in opposing bracket plates may be used to receive a pipe on which wire spools can be hung. The holes in opposing bracket plates can also be used for holding a piece of conduit as it is sawed. If the pipe to be sawed is too large to be received in the holes, it may be cradled in the tapered slots above the holes.

Abstract: A Cathodic Protection apparatus for water supply pipes and especially for the protection of copper pipes in buildings has a pipe section for inserting into the water line entering a building. A pipe section has a pipe coupling on each end thereof for installing the pipe into the water supply line. A sacrificial anode is supported on a rigid conductor and is held axially aligned in the center of a pipe section by a pair of electrically conductive support brackets. The brackets are attached to the sides of the pipe section by adhesive and an electrically conductive bolt is passed through the pipe section and through the support bracket attached to the pipe section and attaches an electrical ground conductor to the outside of the pipe section for grounding the pipe section. Once attached to a section of a building water supply line, the building copper pipes are protected from corrosion due to electrolytic action.
