Round H/D All Plastic

Reinforced all-plastic inserts for round tubing, designed for high-strength and high-torque applications. The extended body prevents twisting or pull-out when lateral force is applied — ideal for use with castors or adjustable feet that experience horizontal stress. Corrosion-proof and vibration-resistant, these inserts perform reliably in wet, chemical, or outdoor environments where steel fittings aren’t suitable.
