Designed to make working on a step, extension or multi-use ladder safer and more convenient, the Professional Ladder Utility System Master Kit contains a ladder mount, tool bucket with carrying handle and a universal tool holder. The tool bucket can be mounted on either side of a ladder, and the ladder mount secures the tool bucket at working level. Units feature a safety latch, safety strap and level-ling adjustment block. The tool holder is designed to hold various tools that do not fit in a tool bucket.
