1 1/2" (3.8 cm) Round Corner Square Extension with Helix

Extensions with helix are placed directly after the lead section (no bare extensions in between). They are used when additional bearing area is needed and to develop increased installation torque.

Hot Dip Galvanized per ASTM A123.

Description
