A spring gate set consists of 4 parts: the gate handle, gate handle insulator, gate spring and the insulator for attaching the spring. PATURA spring gate sets contain an especially large spring and are suitable for all gate widths from 3 to 5 metres. In the opened condition the spring carries no current, contracts to about 25 cm and hangs down, with the handle, from the gate post. To shut the gate, the gate handle and spring are attached to the gate insulator on the other side of the gate. Which then allows current to run inside the handle and through the spring.
