Hi everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at this replacement vertical bolt for the Roadmaster Sterling and Sterling All-Terrain tow bars. Now, if you need to replace the vertical bolt that secures your tow bar arms to the shank on your Roadmaster Sterling or Sterling All-Terrain tow bar, this is the bolt that you are going to need. Specifically, this bolt is going to work with the Roadmaster Sterling or Sterling All-Terrain model numbers RM-555, RM-575, RM-576, RM-585, or the RM-586. Now, let me give you just some brief measurements here.
Looking at the length of the bolt, measuring from below the head to the end of the bolt itself, we're sitting at 4 3/4 inches long. The diameter of this bolt is 3/4 inches on that diameter. And then the height of the head, we are sitting right at 3/4 of an inch. Now, since this bolt is the replacement from Roadmaster, you can trust that it is going to work with the aforementioned model numbers of your Roadmaster Sterling or Sterling All-Terrain tow bar. Well, that's gonna conclude our brief look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..
I bought all new parts to rebuild my 2003 vintage Roadmaster All Terrain Tow bar. Cleaned, installed, and now it performs like a brand new unit. I found the videos by trailer very helpful during the process.
Part came in as promised and appears to be a direct replacement for the original.
Replaced broken parts. Great
