Video Transcript for Roadmaster Safety Chains and Cables RM-910648-20 Review

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.

great little cables. Just long enough to put through the frame of my jeep. I use these to attatch my tow cables. Made hooking it up very easy. Love them.

cables are still working great for towing my jeep behind my motorhome. They make hooking up the safety cables easy.

I always use etrailer when Im looking for products to address a specific application. These safety cables are being used on my 2016 Jeep Wrangler which has a custom offroad bumper installed. I needed cables that would fit through the lower bumper and were no longer than 20 inches, but had at least a 6000 lb capacity. These type of cables were the only ones that would address the problem and they work great. I will continue to shop at etrailer since you have the best overall selection that I have seen.




by:

These cable extenders were exactly what I needed. My tow bar for my jeep was set up for pulling with my pickup, however when I wanted to pull with my motorhome, I had to add a riser which made the cables too short. I therefore ordered the cable extenders and now they fit perfect.

  • Will Safety Chains Damage Bumper On 2018 Chevy Volt With EcoHitch Invisi Trailer Hitch Receiver
    I spoke with EcoHitch about the EcoHitch Invisi Trailer Hitch Receiver part # 306-X7338 and they stated that you'd actually run the safety chains behind the bumper from underneath to avoid them hanging down and causing damage. If you are still worried however you could use the Roadmaster 20" Safety Cable Extensions part # RM-910648-20 which are coated so even if contact were to occur it would not cause damage.

  • Adapter for Falcon Tow Bar With Rock Hard 4x4 Patriot D-ring Bumper
    As long as the bumper you mention is rated by its manufacturer for towing, you won't need a base plate. The Roadmaster # RM-522 Falcon All-Terrain tow bar can be used on a D-ring bumper like the Rock Hard 4x4 Patriot Bumper if the proper adapter is used. You'll need to remove the D-rings on the bumper and measure the width of the tab that they attach to. If the tabs are 3/4 of an inch wide, use # RM-035 or # RM-035-1 if the tabs are 7/8 or 1 inch wide. Because D-ring bumpers don't typically...

  • How to Attach Tow Bar Safety Cables to D-ring Bumper When Flat Towing Jeep Wrangler
    To make the physical connection between the Roadmaster # RM-676 Nighthawk tow bar and the tab the D-ring is connected to, you'd need the # RM-035 for 7/8 or 1 inch wide tabs or # RM-035-1 for 3/4 inch wide tabs. I'd also recommend you check with the manufacturer of your bumper to make sure it's rated for towing the weight of the vehicle. For the safety cables, since you're not using traditional base plates and there's no apparent place to mount the cables you'll need to use extensions...

  • Hitch Extender for Towing Small Trailer
    As long as you are staying within the manufacturers specification in regards to the weights you will be perfectly fine. The Curt Extender # C45796 has a tongue weight capacity of 350lbs and 3500lbs towing or 50% of hitch capacity, whichever is less. In your case for your 2014 Subaru Outback that would be 300lbs tongue weight and 2150lbs towing. You will also more than likely need a Wiring Extension # HM47004 as well as Safety Cable Extensions # RM-910648-20. Be sure to keep these secured...

    When using d-ring mount adapters like the Blue Ox Aftermarket Off-Road Bumper Adapter - 7/8" Pin # BX88357 you'll need to attach the safety cables, like part # RM-643, to the frame of the vehicle.
