Guide rings for greenhouse to train e.g. fruit or tomato stems - are clamped around plant stems on horizontal and vertical tie wires

摘要

The retainer type guide rings, consist of two hinged semi-circular ring halves, which at the free end have locking parts. One ring part has a hooked configuration, to secure this around e.g. vertical or horizontal tie wires. Horizontal and vertical tie wires (1,2) are supported inside a tomato culture greenhouse. Retainer (3) is clamped and consist of two hinged parts (4,5) with hinge (7). The hinge parts are serrated inside to increase grip onto the vertical wires. The plant stems are led through the guiding centre part. The bracket shaped piece (12) allows the guide rings to be clamped to the horizontal tie wires.
