Video Transcript for Roadmaster Safety Chains and Cables RM-910648-8 Review

Today we're going to be taking a looking at the Roadmaster 8 inch safety cable extensions. These are going to extend the length of your towing system, without having to buy new safety cables. Extensions add on an extra 8 inches, so you can use high low receivers, hitch extensions, and other accessories. It's going to come with both cables, and it's going to come with the quick links. The cables are a braided steel construction. Nice strong, durable design.

Here in the center it's going to have a vinyl coating. The coating is going to help keep the cables from scratching any component of your towing setup. The cable portion, with the vinyl coating, has a diameter of around 3/8 of an inch. The quick links are made from a steel construction, with a zinc finish to resist rust and corrosion. They feature a threaded connector right here, for easy connecting and disconnecting. It can be done by hand, or you could use a wrench if you want to.

A 5/8 inch wrench, or a 15mm wrench would work well for this unit. I want to give some measurements right here of the actual quick link. If we take a look at the overall length and width, measuring from outer edge to outer edge, that's going to measure about 3 and 3/16 of an inch going that way. About 1 and 9/16 of an inch going this direction. Pretty close to 1 and 5/8 measuring from the outer point of the barrel to the side right here. The opening that we have between these two areas right here, so measuring the opening of that gap. That's going to measure pretty close to half an inch, about 7/16 of an inch, right in that area.

Internally . I also want to mention real quick, that the diameter of the unit is going to be 3/8 of an inch. You can see here that the threaded portion of the quick link is a little bit larger in diameter, that's actually going to have a diameter of about 7/16 of an inch to 1/2 an inch. These simply allow for easy connecting and disconnecting of the cables. If we measure the usable space on the inside, going lengthwise, we're looking about 2 and, pretty close to 2 and 1/2 inches, maybe 2 and 9/16. If we measure right below that barrel, that's going to give us about 3/4 of an inch.

If we measure right to the barrel, we're looking at about 5/8 of an inch. These are very easy to use. Again, nice strong, durable construction. They're going to add, or offer, about 8 inches of extension. They have that 8,000 pound capacity. That's going to do it for today's look at the Roadmaster 8 inch safety cable extensions. .

These extended my chain connections on my truck, making it much easier to connect for towing. All are high quality and have been in daily use. Look like new. I would buy them again. 543417

Purchased the Swagman Traveler XCS Platform Style Rack bicycle rack mounted on a 15 ¾ “ Hidden Hitch ball mount. It allowed me to tow 2 bicycles mounted on the hitch and still tow our 15 ft. pop up camper. After a year on the road hauling the camper, I could not be happier. The Swagmen bike rack is superbly engineered and manufactured. The designers seemed to think of everything as far as usability and durability. I definitely recommend also using the Roadmaster Quiet Hitch Anti Rattle device. It provided positive clamping to eliminate tow bar movement within the hitch receiver. Also purchased the Roadmaster 8” Safety Cable Extensions which were needed to allow attachment of the safety chains which were not long enough to reach the hitch mounting once the longer ball mount was installed. Also praise to Kelsey W. at etrailer.com who assisted me by answering my questions and guiding me through the sale. All equipment arrived within the time promised and all in good shape. 504199

Thank you for the email. I do have a copy concern. The part i bought has an advertised breaking capability of 8000 lbs, but the quick links only have a 2200 lbs strength. What am i missing? 575928


Comments

Thats a great question. The 2200 lb figure from the quick links refers to the Working Load Limit of the quick links, which applies when the gate or threaded portion of the link is open not fastened. When the gate is secured, the breaking strength is 5 times the 2200 lb working load limit, or 11000 lb. In this case, the cables are rated at 8000 lb so capacity of the system as a whole is 8000 lbs.

I purchased a new Motorhome which was 6 inches taller then my old one. I was able to use a 6inch high low drop hitch for my tow car, but the safety cables were too short. So I purchased the 8 inch extensions from etrailer. This saved the hassle of replacing my short ones for longer ones and saved the cost of replacing. Thank you etrailer ! 308676

The cable extension was perfect for my 5x8 cargo trailer chains when towing with a RAM 2500 (and now 3500). Had to use a ball mount with a 10" drop to get the trailer level, and this extension was just right for the extra length this required. The quick links were a little small for the chain attachment on the truck, so I replaced these with a larger clevis hook. Very satisfied with the quality of the parts. 635511

Product was just as described. Worked well to extend chain length. Poorly packaged. 577715

The product seems very durable and looks exactly as described. The most helpful part of the description was the exact size between the ends of the loops. It fit my towing assembly perfectly. I haven't used it yet, but this extension looks thicker than the safety cable I am trying to extend, so I have no worries about how it will perform. 547318

After looking at several local stores, I finally found these. Nothing else had the weight rating I was looking for to pull my travel trailer. I have a 6" lift on my truck so most trailer chains won't reach any longer. These solved both problems! Great quality & work great! Highly recommended if your truck is lifted. 426918

Great product, built very stout. Made up for the few inches I needed for my trailer to work with my new truck instead of a complete replacement. Shipped fast to, arrived earlier then expected. 276020

Incredible customer service! Unsolicited direct contact from a customer service rep after my purchase to ensure that all things were good to go. I'll be back when I need more trailer parts!! 202533


Comments

They work great. Put on a new actuator that lengthened the neck of my trailer. This made a quick fix without having to replace the safety chains.

Ask the Experts about this Roadmaster Accessories and Parts
Do you have a question about this Accessories and Part?


  • Is the Weight Capacity of the RoadMaster Safety Cable Extensions Per Pair
  • I spoke to my contact at Roadmaster about the RoadMaster 8" Safety Cable Extensions part # RM-910648-8 and they stated that each cable is rated for 8,000 lbs but that does not means it will give you 16,000 lbs in total as if one were to break, you will still only have a 8,000 lb capacity. This is going to be true for most safety cables and chains. If you need something higher then we have the Demco Safety Cable Extensions part # DM9523064 which are rated at 14,000 lbs and have a 12" extension....

  • Troubleshooting Flat Tires When Towing Mini Cooper With 2011 Holiday Rambler
  • First, before flat towing your 2011 Mini Cooper, be sure the tires are filled to the recommended psi and in good condition. More importantly, be certain your steering column is not locked; if your tires are unable to turn they would wear out quickly. If you think your safety cables may be an issue, and yours are shorter than 7', an option would be the Blue Ox Blue Ox 7' Safety Cables # BX88197. Another thing you could do is add an anti-rattle device such as the Blue Ox Hitch Receiver...
