The butterfly clip is a two‑part plastic fastener that folds and locks together to grip shade cloth, insect net or other greenhouse fabrics without tearing them. It is made from UV‑stabilised plastic so it withstands strong sunlight and outdoor weather, making it suitable for long‑term use in net houses, shade houses and fences. The clip can be attached directly to support wires, ropes, pipes or hooks to tension the netting and keep it in place, and its simple snap‑lock design allows quick installation and removal. Typical uses include securing shade net above greenhouses, closing side curtains, fastening windbreak nets and hanging protective covers around crops.
