Ribbed Crimpable Hook

• Ribbed crimpable hooks attach securely to rectangular and round archwires.
• Unique inner rib design produces acceptable force loads when hook is tightly cinched onto wire.
• For best results, use with rectangular wire sizes 0.41 x 0.41mm (.016" x .016") to 0.56 x 0.71mm (.022" x .028").
• Hooks also grip round wire sizes 0.41mm (.016") to 0.56mm (.022").
