Poly all thread risers are used to raise or extend threaded sprinkler, fitting and pipework connections in irrigation systems. The all-thread design provides a threaded body for installations where the riser may need to be adjusted or installed to suit the required connection height.
This 20mm x 150mm all thread riser has 20mm (3/4") male BSP threading along the riser body. The UV stabilised poly construction is designed for outdoor irrigation use and is suitable for compatible poly, PVC and threaded irrigation fittings.
