chain pocket/rail question?

The C hooks look like rubber tarp strap holders not for chains, the gap that the winch slides in may or might not be thick enough to hold a chain or binder, you can buy weld on tie downs or best to buy a thick steel strip and weld it to cross members all the way down bottom sides of the bed of your truck that hooks can be wrap over an hooked so a slack chain cant come off on bad roads?

 

I would say the bar thats welded to the crewmembers is what you fasten to. I wouldnt be crazy about that system but not afraid to use it either. I've seen it before. Usually on straight trucks deliver lumber etc.

 

I assume you just bought this truck? Like I said before it looks like a lumber or drywall delivery truck to me. I see them without rub rails fairly often. You could add those chain pull ups if you wanted but make sure you tiw them to the crewmembers to be safe. If its not 102" already the safer and more practical thing to do is to get a conventional rub rail added to it. Then chain to the spools and use the existing straps. Depends what your plans are and how much money you want to spend.

 

You can buy long sec. of winch slide track at trailer or truck parts store and weld it on other side of winch you have now if you leave some space next to side rail for a chain to be hooked around it.
