You've got two culvert sections to join and you need them locked together tight before the dirt work finishes - a gap or shift at the joint means infiltration, erosion, and a job that has to be redone. A proper culvert band clamps the sections together firmly and keeps the joint stable through backfill and compaction. 12-inch diameter to fit standard corrugated metal culvert pipe. 2-foot band length gives you plenty of overlap for a solid joint on both sides of the connection. Galvanized steel construction fights rust and corrosion through wet Iowa and Nebraska seasons - this is the fitting that stays together season after season without needing to be dug up and replaced. Standard on drainage and culvert work across Knox County, Cedar County, and Plymouth County. In stock at Crofton Lumber Stocked at Crofton Lumber and Akron Lumber.
