Master Link for Ladder Chain

Urethane-covered cables forming a ladder chain are interconnected by master links fastened with swedged collars.

Each master link assembly includes two cross members fastened together by retainer clips. The cross members are fastened to the cables by swedging cylindrical collars on the cables and into a conical cavity in the cross member. The cross members are then held together by retaining clips.

Swedging provides a secure joint without the application of deleterious heat. In addition, the joint is self-tightening because the cross member acts as a die which forces the collar onto the cable as tension is applied.
