Video Transcript for RoadMaster Single Hook Straight Safety Cables Installation - 2014 Ford Focus

Speaker 1: Today, on our 2014 Ford Focus, we're gonna be taking a look at and showing you how to install the Roadmaster 76" single hook straight safety cables. Part number RM-645-76. If you ever flat towed a vehicle before, you're gonna know that you gonna wanna have safety cables. They're just that extra bit of security in case anything we're to happen with out towing set up. They're gonna keep our vehicle attached to our motor home. Not only that, but they are required by law.The cables are made out of an aircraft-type galvanized steel construction, so they're gonna be extra durable and strong.

They're also gonna feature a heavy duty drop forged steel hook. It's gonna have a spring loaded clasp to give it extra security and making hooking them up a breeze. The cables are gonna feature a nice vinyl coating around the outside not only to prevent any kind of rust or corrosion on the cable themselves, but it's also gonna prevent any kind of scratched or chipping on our tow bar itself.On the other end where it's gonna attach to our motor home, we're gonna have some quick links. They're also made of steel. Trying to easily thread on.

We're gonna have that security, but also be able to take them off fairly easily. Our cables are gonna be 76" long. They come in a pair and they're gonna have a total weight capacity of 8000 pounds per pair.We already have our Focus hooked up and we have one our safety cables hooked up, so let's go ahead and put the second one on together. To start out, you're gonna notice that we're gonna have two different ends. We're gonna have one that's gonna have a hook on it, the spring loaded clasp, and one that's just gonna have the braided cable on it.

The end with the braided cable, we're gonna take the quick disconnect link and we're gonna slide it over the end of it.Then, we can move to our hitch and find the safety chain connection points. We're gonna find our safety chain connection point and we're gonna slide the quick link over and secure it in place. Now it's important to criss-cross the cables. We just connected it to the passenger side of our motor home, so we're gonna underneath out tow bar and come over to the driver side and cross over the top of our tow bar to take up some of the slack, and then we're gonna find the hook and find our safety cable attachment point on our baseplate.We're just gonna snap it into place. Now, if you're worried about the slack, it will have a little bit of slack taken up because our tow bar isn't in the fully extended position, but you just wanna go ahead and wrap it around your tow bar.

Just make sure that that final loop goes underneath the tow bar, the center section here where it pivots, and make sure that you do cross the cables.With our safety cables hooked up and everything else hooked up as well, we're ready to hit the road. That'll finish up your look at the Roadmaster 76" single hook straight safety cables. Part number RM-645-76 on our 2014 Ford Focus.

Always good working with e trailer


Tow cables are as described fitting my toe bar. I prefer the straight cables versus the coiled ones thus am quite happy with your product


Arrived quickly and performed as expect ed.


Good quality cables and hardware. Very happy with this. Using for a 2014 Fleetwood Discovery 40G towing a 2018 GMC Yukon Denali w/ Roadmaster Blackhawk 2 and no towbar extension. These are probably a little longer than needed with this setup, but I figured a little long is better than a little short.


very satisfied with product . delivered in a timely manner


As advertised! I bought this set to replace the set that was damaged after I installed a receiver drop hitch and pulled out of a shallow driveway after fueling. They were the perfect replacement for my Roadmaster Sterling All Terrain tow bar. I used Velcro straps to allow the safety cables to move with the towbar, but not drop below the bar and be damaged.


Exactly what I ordered. Tow bar safety cables will fulfill my needs to safely tow my jeep behind my motorhome.


Good as expected. Originally had 64" but had to get 76" due to using a drop hitch with the Roadmaster tow bar.


Quality product. Service and shipping was excellent. I'd ordered a different set of safety cables that turned out to be too short. I contacted etrailer and the folks there were excellent about coordinating a return and ordering a different product better suited to my setup.


Received my safety cables. I was wondering about the delivery date so I emailed etrailer and they got right back to me with delivery specifics. Arrived as promised by Derick. Excellent customer service and the product is just as advertised.


Right length for my new setup with the hi-low adapter extension.


Great products. Great teachers to explain the product after installation. All the qualities you want in a company you can trust.


No issue with cables.


Nice cover and easy to use, have to use a wrench on the links though can't use your fingers.

After installing two hooks on the open end of the cable it is a lot easier to R

Looks good! 7000 lbs rated also.


This was a great experience in purchasing a product. The website was easy to work with to find my product. The pricing was very competitive and it was shipped and arrived on time. I will definitely shop here again.



Product looks great and should do the job if needed. However the package had been opened and taped closed but all is well with items inside.


Exactly what I ordered, in a timely fashion, at the best net price. What else could one ask for?


Quick delivery - as always. Good pricin g.



Troy,you are 2 for 2 .On time and exactly what i ordered...Thanks


Product was just what I ordered, fast free shipping, and price was great!

  • Recommended Safety Cable That Is At Least 64 Inches Long
    The safety cables I highly recommend are from Roadmaster, the Single Hook, Straight Safety Cables. These cables are galvanized steel with a strong vinyl coating for protection and hooks that are forged steel for optimal strength. You can get them in either 64 inch or 76 inch lengths: - 64 Inches (Single Hook): Roadmaster 64" Single Hook, Straight Safety Cables - 8,000 lbs # RM-645 - 64 Inches (Double Hook): RoadMaster 64" Double Hook, Straight Safety Cables - 10,000 lbs # RM-648 - 76...

  • Where are Roadmaster 64 Inch Safety Cables Measured From?
    The Roadmaster 64" Single Hook, Straight Safety Cables # RM-645 is the overall length of the unit. If you are at all concerned with the amount of length I highly recommend going to a longer cable such as the 76" # RM-645-76 or the 80" Double Hook # RM-674.

  • Roadmaster Sterling All Terrain Tow Bar Safety Cables Replacement Recommendation
    For the Roadmaster Sterling Tow Bar the recommended length for replacement safety cables is 80 inches. Roadmaster lists the coiled cables part # RM-674 which are coiled only for a small portion of the cable and are straight for the rest of it.

  • Can The Safety Cables On Item # RM-576 Be Changed To Make It Compatible With Item # RM-524431-5
    The Roadmaster Sterling tow bar Item # RM-576 is compatible with the Roadmaster Direct-Connect Base Plate Kit Item # RM-524431-5 however, the safety cables are not. The current safety cables would need to be removed and you would not use the quick disconnect bar. Each arm will pin directly to the removable tabs on the baseplate. For safety cables I recommend RoadMaster 76" Single Hook, Straight Safety Cables - 8,000 lbs Item # RM-645-76. Installing these on the tow bar is simple. Make...

  • Weight Capacity Per Cable And Hook Dimensions For Blue Ox, Roadmaster, And Demco Safety Cables
    The weight capacity listed for cables is for the pair. For example the Blue Ox 7' Safety Cables - 7,500lbs # BX88196 you referenced would have a 3,750lb capacity per cable. Since Roadmaster doesn't have a 7,500lb cable I'm assuming you're referencing the RoadMaster 76" Single Hook, Straight Safety Cables # RM-645-76. I've drawn up some dimensions for these two cables as well as the Demco Coiled Safety Cables # DM9523003 you referenced below.

    I checked the online version of the owner's manual for your 2011 Nissan Sentra 5 speed manual. I recommend checking your manual as well, but Nissan states that it can be towed with all four wheels on the ground as long as the ignition is off, the steering wheel is secured in the straight-ahead position with rope or device (factory wheel lock is not sufficient), and the shift selector is in neutral. Here are the parts that I recommend going with in order to properly flat tow your 2011 Nissan...

  • Parts Needed to Flat Tow a 2013 Chevy Traverse Behind an RV Using a Sterling Tow Bar
    For your 2013 Chevy Traverse and Sterling tow bar I recommend the EZ4 base plates # 523175-4. Base plates can be tricky to install so I have included a link to the instructions so you can see the steps ahead of time. In addition to the tow bar and the base plates you will also need safety cables (if the tow bar did not come with any) # RM-645-76, lighting, and supplemental braking. For lighting you can use a simple magnetic kit such as # RM-2120 but for a more permanent solution I recommend...

For this, we have 1/2" options like part # TCSLIP-G70-13-L as well as 5/8" options like part # C81920.

Just pull the pin and clip on each leg and release the crossbar from the tow bar. Note: This baseplate was designed to fit a factory bumper, if you have something else let me know.

    Yes, you can flat-tow a 2013 Ford F-150 Eco-Boost however, you will need a lube pump for the transmission if you have a 4x2 model which we do not offer but I can provide instructions on how to obtain this if needed. I have attached the other parts you will need below. The drive shaft does not need to be removed and the lube pump is not needed on 4x4 models.

  • Differences of Roadmaster Direct Connect and Cross Bar Base Plates for 2020 Jeep Wrangler Unlimited
    The main difference between the Roadmaster direct connect base plate kit (previously known as the EZ5) # RM-521453-5 and the cross bar style base plate kit (previously known as the EZ4) # RM-521453-4 is how the tow bar attaches to the base plate. The cross bar style base plate uses a quick disconnect bar to connect the tow bar up, the direct connect uses pins and clips to mount to the tow bar. They install exactly the same, the arms are the only difference. A direct connection makes it...

  • Mounting Location for Stay and Play DUO Operating Unit
    When I installed the Stay-IN-Play DUO # SM99251 in a 2018 Jeep Grand Cherokee I mounted the operating unit in the front of the engine bay on the core support. You can mount the operating unit anywhere that the wires and hoses can reach; it's just recommended that it mounts in the engine bay away from direct water exposure and extreme heat sources. After installing many flat tow set ups on different vehicles, the biggest piece of advice I can give you is to plan out your install. Take a...

You will also need safety chains, Roadmaster # RM-643 for 68" chains or # RM-645-76 for 76" chains.

  • 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.

  • Parts Needed to Flat Tow a 2013 Buick Enclave Behind an RV
    The first thing to do is check the capacity of the hitch on your Winnebago. The weight capacity of a Class III hitch varies. There should be a sticker on the hitch but if not the capacity is probably in the RV literature. Assuming that the RV and hitch are rated high enough you will need base plates, a tow bar, safety cables, lighting, and supplemental braking to tow your 2013 Buick Enclave. Starting with the base plates # 523149-1 is an excellent choice. The arms can be removed when not...
