One new item  that we developed  named IMO container lashing , 
4 Points each side to reach much higher securing force


Since the lasted revision of the  IMO guidelines the max. force which should be applied to the lower container lashing point is

1000KG and just 500KG to the upper point.
Using two sides, that gives a max. strength of 3 tons. By using 4 instead of 2 lashing points on each side of the container we can reach a much higher securing force..
