A bulk lot of threaded irrigation pipe risers — a mix of galvanised steel and green PVC, in assorted lengths (roughly two dozen pieces). These are the short threaded uprights used to raise and connect sprinkler heads to an irrigation supply line. Some still carry their retail barcodes, and one is labelled 15 × 150 mm. A handy grab-bag for setting up or repairing a garden watering / sprinkler system. Sold as-is as a job lot.
