• Screws are cut at both ends of the metal body, and one is right-threaded and the other is left-threaded (reverse threaded).
• Rotating the body tightens (or loosens) the bolts at both ends, allowing the tension to be adjusted.
• The material is iron and not plated.
• Used to adjust the tension.
• Used for temporary buildings, lightweight buildings, agricultural and horticultural houses, tents, signboards, plants, packing materials, antenna pole support, etc.
• Because the fabric is rustable, it should be used under oily environment or where corrosion resistance is not required.
