Review of Roadmaster Accessories and Parts RM-643


Today we're going to b reviewing part number RM-643. These are the RoadMaster 68" Single Hook, Coiled Safety Cables. They're going to have a capacity of 6,000 lbs. They're going to offer extra security for you tow system. The cable is made from a aircraft-type, galvanized steel construction that's going to offer a superior strength. It's also going to feature the heavy-duty, drop-forged steel hooks that have a spring-loaded latche for added security. That's just going to help people to average what's inside the hook, inside the hook and keep it from becoming disengaged.

The cables have a nice vinyl coating that's going to keep the cables from scratching and chipping your tow bar system. Another neat feature is here on the eyelet of the cable, it has a nice solid steel piece. That way it allows the hook and the other connection for and through rotate freely around there. Without freeing or unthreading the actual cables. That's a great feature to have. You're going to get 2 safety cables. They are coiled, but they're going to have an overall length of 68" and a capacity of 6,000 lbs.

Now, here on this connection point, I have one of them unthreaded. Really easy, all you have to do is thread it back up. It's going to secure and place. If I have one of them opened as if we're getting ready for connection. I have one of them as if we're already connected.

The opening that this one gives us is going to be a half inch to slip over the connection point. Here on the inside of that hook, that opening is going to give us 2 5/8". Then this direction, it's going to give us a measurement of 5/8". That's going to do it for the review of part number RM-643. These are the RoadMaster 68" Single Hook, Coiled Safety Cables. .

My safety cables have a ball at one end, where does the ball fasten to baseplate kit 52289-5

Reply from Chris R.

The Base Plate Kit # 52289-5 does feature integrated safety chain tabs at the front (see answer page linked below). This is where you will attach your existing cables.

Do I need to replace my coiled cables if Im missing some of the blue covering?
Etrailer Expert
Reply from Jon G.

If some of the covering is missing I wouldn't say that warrants purchasing new cables as the covering is in place to help with longevity of use. If you start to see wear in the locations where that covering is missing though, that would be a good time to purchase new cables. I am linking our selection of safety cables that you can filter through.
