The “new design” fully swiveling head is fitted with high tensile stainless steel pins. The swiveling stud eye is fitted with a bronze thrust bearing, which has solid lubricants for free movement under load.

The new design swivel allows the trawl block to tilt to any angle when turning to port or starboard during towing, preventing the warp from rubbing on the frame of the block.

Maximum load on the head fitting is 25 tonne.
