This extended length check strap allows the back door of a Toyota RAV4 to open wider than normal. The item was easy to fit, three 10mm nuts, and 30 minutes work. I found the door to be a lot stiffer to open and close than previously but with a bit of grease and use that has started to loosen. Overall a good investment to enable you to open the back door of your RAV4 to more easily load large items.
