The ground spike is part of the Kärcher Rain System. It securely fixes the Kärcher Rain System hose and the drip hose in the desired position and establishes the necessary distance from the ground. The 17 cm long ground spike features a marking aid for conveniently determining the optimal insertion depth. The rubber ring on the eyelet ensures a secure fixation of the hoses. The Kärcher Rain System combines the advantages of micro-dripping and conventional irrigation. The highly efficient Kärcher Rain System operates at pressures of up to 4 bar and offers a 1/2" hose with drip and spray cuffs. The Kärcher Rain System can be individually adapted to almost any garden and works perfectly with the SensoTimer for demand-based irrigation control.
