A true blast from the past - now back in stock for a limited time only. Originally produced in the 1970s on machines long retired, our 4 in. Heavy Duty Pinhole Pipe offers unique drainage performance that old-school contractors still swear by. Crafted with tiny precision-drilled holes, it's ideal for yard drainage applications where knife-cut pipe is typically used. Resurrected for small-batch run, our 4 in. Heavy Duty Pinhole Pipe has a limited inventory and larger contractor orders may have quantity limits. Be sure to place your order soon before Pinhole Pipe disappears again!

Our specially designed 4" knife-cut line of High Octane® is best for fine and sandy soils. The perforations resemble a knife slit, just big enough for a piece of paper to enter but allows for minimization of infiltration from fine soils or sand. This type of material is a more cost-effective alternative to using the filter sock material and is used in many agricultural applications.
