The ‘V-notch’ of this sturdy M-1070-1R block wedges on the strand for new build construction or two .750” cables fit between the frame and retaining pin for overlash jobs. The steel gate retains the cable being pulled out. The rubber roller of the M-1070-1R supports a cable up to 1 1⁄2”.

Note: Cable blocks are not to be used as snatch blocks or adjacent to powered cable pulling rigs, winches or when cable is pulled with vehicular assistance.

The sufficient use of mid-span blocks is a key factor in maintaining safety, gaining production, and quality installed cable. Placing blocks approximately 30 to 35 feet apart will keep the cables straight, reduce the required pull-out pressure, and maintain the round configuration of the cables. Using a block at each pole and perhaps one in mid-span causes deep sags, increases pull-out pressure, and sacrifices production, cable configuration, system life and safety.
