Anchor Shackle Introduction

Anchor shackle also called D shackle, or U shackle, is made of hot dip galvanized forged steel, the cotter pin is made of stainless steel. It's one of the most important link fittings for the insulator strings. The anchor shackle is to be fixed on the crossarms of poles, and the other side is to be linked with ball eye, tension clamp or suspension clamp. The dimensions of the anchor shackle are compatible with the ball-ended eye links and cross-arms of associated steelwork.

Standard: BS 3288, IEC 61284, BS 729, ISO 1461, ASTM A-153.

Types of shackles: U shackle, Twisted shackle, Vee shackle, Twisted strap.

4. Application

The anchor shackle is a super important link fitting to connect the tower and insulator strings.

D shackle

Forged steel shackle

The anchor shackle is made of forged steel, the surface is hot dip galvanized according to BS 729. The mechanical strength range is 40kN-530kN.
Forged steel shackle, also called D shackle, is an important component for the complete hardware fitting strings to connect the cross-arm and ball eye, or other link fittings for the transmission, distribution lines, and substations.
