I never had a good set of straps for my trailer and hated the ones I did use so I went and bought these the other day from my local Canadian Tire. Just had to drill a single hole on each side and mount with a bolt. The nice thing with these is they ratchet but also auto coil when unhooked. I'm sure these are pretty much the same as any newer trailer come with but just thought I would share with others that have older trailers.
