from the direction of pull. Make the front hole about 1 1/2 to 3 feet deep and the rear hole 2 feet deep (fig. 6-44). After driving pickets into the holes, you should secure the guy to the front picket. Then lash the pickets together with a chain or wire rope to transmit the load.
Pickets used in the construction of picket holdfasts may be made of wood or steel. A wood picket should be at least 3 inches in diameter and 5 feet long. A single picket holdfast can be provided by driving a picket 3 to 4 feet into the ground, slanting it at an angle of 15 degrees opposite to the pull. In securing a single guy line to a picket, you should take two turns around the picket and then have part of the crew haul in on the guy as you take up the slack.
