Sits between the tension hook and the extension link and is how sag and tension are actually set on site. Right-hand thread one end, left-and-right the other, so turning the body draws the assembly in or lets it out without twisting the cable. Forged mild steel to IS 2004, hot-dip galvanised to IS 2629.
