Combo Piles

MacLean’s innovative and industry-leading design of the Strength Square™ pipe coupling system allows for square shaft leads to be directly coupled to round extensions without requiring additional components to purchase. MPS Combo Piles allow for the smaller profile square lead to penetrate tough soils and dense lenses while the round extensions provide excellent lateral support.
