Carson makes the HDPE valve boxes and enclosures that protect the parts of an irrigation system nobody sees until something goes wrong. The boxes are built to take vehicle and foot traffic, resist UV, and stay serviceable after years in the ground.
Our Carson range covers 910 round 10 in. boxes, 1220 (20 in. x 12 in.) and 1419 (19 in. x 14 in.) rectangular boxes in 12 in. depths, matching 6 in. extensions to build up to grade, and T-lid covers in green, black, tan, grey and purple. Purple lids identify reclaimed and non-potable water in line with common colour-coding requirements.
