These worked very well when installed on my trailer. If a was able to change anything on these I would add a quick cli[p to the pins that secure them to the trailer. The Stainless cotter key is great if you don't want to use these on different trailers. I have several trailers I use these on depending on what I am going to pickup. They were thinner than the ones I was used to using, however I found out these worked really well at the back of the trailer where the slots were thinner because of the Lights. They also have some ratcheting ones that I really like but they only have a 5400 lbs.
