Review of Roadmaster Accessories and Parts RM-910648-20


Today, we're going to be taking a look at the Roadmaster 20 inch Safety Cable Extensions. These are going to extend the length of your towing system without having to buy new safety cables. The extensions are going to add 20 inches, so you can use high-low receivers, hitch extensions and other accessories. It's going to come with two cables and two quick links. These are going to be rated with a capacity of 8000 pounds. The cables are a braided steel construction with a vinyl coating. So that coating is going to keep the cables from scratching any component of your towing setup.

The cable portion with the vinyl coating is going to give us a diameter of about 3/8 of an inch. Now these quick links are made from a steel construction with a zinc finish. They're going to do a great job at resisting rust and corrosion. It's going to feature a threaded connector for easy connecting and disconnecting, that can be done by hand, or you can use a wrench. This will accept an 5/8 inch wrench or a 15 millimeter wrench. A few measurements that I want to go over with the quick links. I want to go over the overall measurements, so from outer edge to outer edge going this direction, we're looking at about 3 3/16 inch to 3 1/4.

Then going this direction to the outer edge of that barrel, we're looking at about 1 9/16 to 1 5/8 of an inch. Now the opening, measuring the gap right here, that's going to give us a measurement of pretty close to 7/16 of an inch. The diameter of the actual link is going to be 3/8 of an inch, but that threaded portion has a slightly larger diameter. That's going to give us a diameter measurement of about 7/16 to 1/2 of an inch. We'll go over the internal measurements as well. So the usable space from inside edge to inside edge, it's going to be about 2 1/2 inches.

Measuring the usable space, just below that barrel, we're looking at about 3/4 of an inch. Then, to the flat side of the barrel, we're looking at about 5/8 of an inch. Again, these are going to add 20 inches of extension to your towing system. They've got the nice strong connection points on there as well and again, they're just a nice strong durable unit. That's going to do it for today's look at the Roadmaster 20 inch Safety Cable Extensions.
