The depth of the outlet will range dependant on the ground circumstances plus the construction that’s currently being retrofitted or developed.
Caution spend near awareness to how the shackle is orientated. It can be done which the hoist line useful for the pile hammer may rub, then possibly dress in the cotter pin, triggering probable harm to the hoist line or the cotter pin (important) staying dislodged with time.
