1/4 inch tubing fits into the stake. Perfect for drip systems. The spray is angled at the growing medium at 45 degrees (hose sold seperately). The advantage of the Angle Stake is its long neck which holds the 1/4" tubing securely in place. The angle of the stake helps prevent deposits in the tubing. This angled dripper stake fits 1/4" tubing and has a 45° angle to reduce sharp bending of the tubing, which causes clogging. It delivers a light emission of water for regular top drip irrigation.
