Today we're going to be taking a look at the Roadmaster 10" 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 an extra 10" so you can use Hi-Low Receivers Hitch Extensions and other accessories. It's going to come with both cables and 2 quick links. These are going to have a capacity of 8,000 pounds, the cables are a braided steel construction then they have the vinyl coating over the center area right here. The coating's going to help keep the cables from scratching any component of your towing setup and then the cable portion right here with the vinyl, that's going to have a diameter of around 3/8". The quick links, that's these right here, these are made from a steel construction with a zinc finish to resist rusting corrosion.

They do feature the threaded connected for easy connecting and disconnecting. That can be done by hand or you could use a wrench. This will accept a 5/8" wrench or a 15mm wrench. A few measurements that I want to give you real quick regarding the quick link, if we take a look at the overall length that's going to measure about 3 3/16", 3 1/4" right in that area. If we measure the overall width to the outer point there of the barrel, that's going to give us a measurement of about 1 9/16" or 1 5/8" right in that area. The opening that we have right here that's going to give a measurement of about 3/8".

I do want to point out that the diameter of the link right here is going to measure 3/8" but the threaded portion has a slightly larger diameter that's going to measure about 7/16" or a 1/2". Now we'll take a look at the internal dimensions, so the usable space that we have there on the inside, it's going to be about 2 1/2" inches measuring right below that barrel the usable width, it's going to be about 3/4" and then to the barrel on the flat side is going to be about 5/8". The units are really easy to use, the cables are a nice, strong design, strong connection points, vinyl coating, braided steel. A nice, strong, dependable unit and again from the inside edge of this loop to the same point on the other side, that's going to give the 10" extension or 10" length of each cable. That's going to do it for today's look at the Roadmaster 10" Safety Cable Extensions.

Ask the Experts about this Roadmaster Accessories and Parts

  • Would 68 inch Coiled Safety Cables be too Short If they Stretch Out When Installed
    As long as the cables have enough slack built into them so that you can make tight turns without issue the cables you have would work just fine. If they get so tight that the attachment points look strained or the cable is totally straightened (since it's coiled) it would be too short. Otherwise we have an 80 inch Roadmaster coiled cable, part # RM-653.

  • Will 1/2" Outer Diameter Hook Work With Roadmaster 10" Safety Cable Extensions
    I confirmed with one of my contacts at Roadmaster and confirmed that the # RM-910648-10 will accept a 1/2" outer diameter hook. Because the quick link length of 3-1/4" will allow its connection. I have the measurements of this product attached.

  • Parts Needed to Flat Tow a 2013 Chevrolet Suburban
    I looked in the owners manual for your 2013 Chevrolet Suburban and it can be flat towed or dolly towed, depending on if it's 2 or 4 wheel drive, and if it has a single or two speed transfer case. If you suburban is 2wd or has a single speed transfer case, it can not be towed with all 4 wheels on the ground, and can not be towed with the front wheels on a dolly. So if your Suburban is 4wd with a 2 speed transfer case it can be flat towed (all wheels on the ground) or dolly towed. There...

  • How to Pick Out Correct Rise/Drop High Low Adapter for Flat Towing Vehicle
    If you check out the picture I attached you can see that when picking out a high low adapter for a flat towing setup you need to have the tow bar sit within 3 inches of level to be "safe." Otherwise suspension and tire damage might occur. First thing you need to do is measure from the ground to the top of your hitch opening on your tow vehicle and then measure from the ground to the center of your base plate kit on your towed vehicle. The difference in these two figures is the amount...

  • Comparing the Curt Tri-Ball Mount D900 and Buyers Products Tri-Ball Mount 3371802225
    The Buyers Products Adjustable Tri-Ball Hitch part # 3371802225 and the Curt Multi-Ball Adjustable Ball Mount part # D900 are both very similar. The main difference as you mentioned is that the Buyers Products Ball Mount has a longer shank which then allows for more rise/drop adjustments. The more rise/drop adjustments you have, the greater number of trailers you can tow level. In regards to the manufacturer, both Curt and Buyers Products are reputable brands so I would not let this alone...

  • Recommended Parts to Flat Tow a 2020 Jeep Cherokee Trailhawk
    To tow your 2020 Jeep Cherokee Trailhawk behind a motorhome there are several components you need for a complete, safe set up. The first is a base plate, I recommend Roadmaster direct- connect base plate kit part # RM-521451-5. The base plate bolts to your Cherokee frame and provides the solid attachment point to hook up to. I have installed a variety of base plates on many different vehicles, and Roadmaster's direct-connect is my favorite. I think they install smoother, and have a really...

  • 2018 Jeep JL Wrangler Base Plate Options With Aftermarket Bumper and Winch
    The Roadmaster Crossbar-Style Base Plate Kit # RM-521424-4 is not confirmed to fit your 2018 Jeep JL Wrangler, it is for a different generation of Wranglers with the factory bumper in place. Most aftermarket bumpers have D-ring bumper mounts, and there are adapters to hook the tow bar directly to the bumper. However you will need to check with the manufacturer of the bumper to see if it is rated to tow with. If the Bumper you have is rated to tow and you have 3/4" d-ring mounts you can...
