Securement to trailer
This is the style strap you have. jpg ...126. Those hooks do not fit between the side of the trailer frame and the tiedown rails.
...210.jpg, To get them to fit, grind the outer end of the hook at a 45° angle. Should not take much and will not affect the strength. Then you can drop it between the frame and tiedown rail, come up and hang the hook.
I will try this another way by posting the photos and description individually.
