Abstract
A reinforcement assembly for use in the hand access hole of a tubular shaft. In one embodiment, the assembly includes a pair of units placed opposing each other with one being inside the shaft and the other being outside the shaft. Each unit has a plurality of tenons that mate with open spaces of the opposing unit, and each has a flange surrounding the tenons that contact the shaft in the area immediately surrounding the hand hole. The two units are attached to each other and to the shaft by bolts or other suitable fastening devices. In another embodiment of this invention, the pair of units are positioned one inside the other with at least one mating mortise and tenon union for securely linking the units. A typical application of the assembly is reinforcement of the area surrounding the hand hole of a utility pole.
