Oldcastle Infrastructure

Oldcastle Infrastructure manufactures the Carson and Christy enclosure lines — the valve boxes, extensions and covers that make up the buried access points on almost every commercial irrigation system.
Our Oldcastle range covers 708 6 in. and 910 10 in. round boxes, 1220, 1324 and 1419 rectangular boxes, Jumbo 12 in. rectangles, extension boxes for building up to finished grade, and lids and covers in green, black, tan and purple plus Christy F-8C cast iron water lids for traffic-rated locations. Boxes and lids are sold separately so you can match an existing installation instead of replacing the whole assembly.
