This industry-standard handhole size is included as a standard in many of the poles in this catalog. The opening is oval in shape and measures 4” x 6”, with the major dimension along the vertical axis. The hole in the shaft wall is reinforced with a frame of aluminum alloy 356-T6, which projects slightly through the wall and is completely joined to the shaft with a fillet weld, the minimum size of which is 5/16”. The opening is protected by a snug-fitting cover attached by means of two stainless steel hex head screws. The external contour of the reinforcing frame and cover, although projecting slightly for sound welding, is curved to conform to the roundness of the shaft. The cover has a surface finish which is comparable to that of the shaft. The standard location of the handhole is centered 18” above the bottom of the shaft and will be located 90 degrees clockwise from the plane of the bracket, as viewed from above.
