Greenhouse String Hook - Vine Support

A simple half S-shaped hook for hanging support strings from the roof bars of a greenhouse. Clips directly onto the horizontal frame bar, letting you drop a string down to each plant so tomatoes, cucumbers, and other climbing vines can be trained upright as they grow — no tying knots to the frame, no drilling.

Just loop your twine or garden string through the hook and let it hang down to the base of the plant. As the plant grows, gently wind the stem around the string to keep it climbing vertically, saving space and improving airflow and light exposure.

Compatibility:

- Fits standard aluminium greenhouse roof/ridge bars (flat or slightly recessed profiles) - Works with garden twine, jute string, or polypropylene twine Print settings:
