MULTIPURPOSE LADDER ATTACHMENT
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.
