This thing is so easy to use. I like that you don’t have to be on a level surface to hook up.



by:

Heavy Duty and just as expected, I have not used them yet as my motorhome has not been delivered. My etrailer representative Joshua was VERY helpful.

Great Accessory, looks and works like day one

These safety cables are great! They fit perfectly and slide into the tow bar tracks to make it a very cool and smooth package. I highly recommend them and eTrailer too for the quick delivery.

Great product. I needed longer Saftety Cables after installing a swing away coupler on my boat trailer tongue. This worked out very well. Well designed and arrived on time .


Comments
I am completely satisfied. Great product and great sales staff. I could not be happier.

by:

Used these with the Raodmaster Blackhawk 2 Tow bar and the Direct connect base kit with removable arms. They were easy to run thru the channels on the tow bar and did not hang down excessively. Very easy to connect with the hooks on one end and the O rings on the other. Would recommend!


Comments
The cables are well made and very easy to take on and off. they fit well into the tow bar with ample play to them. Great purchase!

Perfect, correct length, all the parts I needed to make the connection. Thanks, great product.

I have ordered several variations of RoadMaster towing accessories from etrailer over the years. etrailer is always helpful when I have a question, if they don't know the answer, they will send you where you can find the correct parts for your needs. That was the case with this order, my previous hook-up used the EZ hook safety cables. I bought a new Jeep to tow and the new base plate does not accept the EZ Hook Cables. After a conversation with etrailer customer service, they had me call RoadMaster for the solution RM-645 must be used. Ordered from etrailer and in just a few days the cables came in the mail. (I thought etrailer should have given free shipping, after all the products I have bought for over$100.00, but I guess not...) even with economy shipping, the cables arrived in short order. I am one of many satisfied etrailer customers, I'm sure.

After using the new cables for a year, the safety cables fit through the Roadmaster guide channels and have worked flawlessly ever since. I know thwere are other brands of tyowing set ups out there, but I am a Roadmaster satisfied customer!

They were what I expected. They arrived in a timely manner.


Comments
Worked fine when I used them. I am no longer towing.
James - 09/27/2021

by:

Lots of work to install on my 2017 Jeep Cherokee, yet the work as expected!



by:

This cable was made with not only safety features of it’s engineering, but also ease-of-use. They’re pliable enough to maneuver yet rigid enough to keep their shape. The crimp sleeve at the eye was done well eliminating possible jabs from a wire and the hooks are easy to open and close the safety latch.



by:

Excellent communication on shipping. Very efficient process start to finish!



by:

This was part of many Roadmaster components I ordered from etrailer.com to set up my 2014 Honda CRV as a toad. Etrailer's website is excellent and their review videos and installation videos are very helpful. Their tech service department is excellent as well.

These safety cables are well made and fit well in the channels of the Roadmaster Falcon All-Terrain tow bar.

Note the etrailer video shows having to order extra rings to mount to the motorhome side. This is not necessary if you have a new Roadmaster baseplate with wide hole safety cabel attachment points. The looped ends and rings provided on the safety cab els should mount to the motorhome (and stay with the tow bar when disconnected and folded). The other end with the spring hinged hooks easily hook onto the baseplate with wide holes for the hooks.



by:

I ordered both the Front and Rear anti-sway bar upgrade kits. The install on my 2016 E450 was quite simple, and accomplished easily in my driveway. The kit for the front was a simple remove and replace the OEM bar. The rear kit required drilling two holes to accomodate new mounting points. Other than that, it was also simply a matter of removing a few bolts, and replacing the factory bar. Some minor nits associated with the kits. The washers included in the kit for the rear didn't fit the bolts, also included in the kit. And, the instructions for the front kit didn't include torque specs for the bolts. A quick trip to the local hardware store, and a call to Roadmaster tech support solved the respective problems. Oddly, the Roadmaster tech guy read me THEIR instruction over the phone, and they DID include the necessary specs. I've intalled these kits on two different motor homes now. They work GREAT, and I highly recommend them if you're towing and it feels like the vehicle has a bit more roll than you like. HOWEVER, I would note that the difficulty of installation can vary widely. If you're planning to install yourself, I highly recommend downloading the instructions in advance, and crawling under your vehicle to check on accessibility. For the E450 kit, you'll have to be able to get under there with a drill, and not drill through any cables/lines that may run along the frame rails. You'll also have to be able to get a (typically somewhat large) torque wrench up in there. My experience suggests this can be nearly impossible on some vehicles without access to a grease pit or lift. Good luck!



by:

Just What I needed. The quality is excellent and the shipping was "Fantastic"



by:

Very professional, knowledgeable and willing thep guide in the correct items to purchase



by:

Excellent company to do business with. Best prices and quick delivery. I am a repeat customer and will continue to shop etrailer.com. I have saved money and time with every purchase. Shop around and you will find the selection and prices are the best. They also offer help, suggestions and direction for proper and safe use of all their products. They can't be beat.

After a year all is well. The safety cables show no sign of wear and have provided peace of mind for many, many miles.

Got the non-coiled safety cables so I could use the channels in the Roadmaster Falcon tow bar and keep the cables up off the ground. Allows full range of motion of the Rv, Toad, an tow bar. Hopefully I will never have to "really" test these, but they look solid...



by:

Just follow the instructions.



by:

I purchased RoadMaster Safety Cables for my 1993 Jeep Wrangler that was equipped with a StowMaster tow bar. Instructions were provided for several manufactures of tow bars including my StowMaster. Assembly was simple and took approximately 15 minutes and provided for a perfect fit.



by:

The re-build kit and bushing for my tow bar, along with the new cables and extensions made it like new again. Everything I ordered worked as expected and arrived in timely fashion. Thanks for My third good experience with Your company.

Ask the Experts about this Roadmaster Safety Cables



  • Safety Cable Recommendation for a 2010 Toyota Tundra with a Bumper Mounted Trailer Coupler Ball
    What you can do is to use safety cables, like RoadMaster 64 Inch Single Hook, Straight Safety Cables, # RM-645. You can route one end through a hole on the bumper, pull it about half way through, and then attach both ends to the trailer.

  • Can Roadmaster Safety Cables Connect to 7/8 inch Diameter Hole of Base Plate Kit
    Yes the Roadmaster safety cables part # RM-645 would connect to a 7/8 inch diameter hole on the base plate kit using the connectors that come with the kit.

  • 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.

  • 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...

  • Is a Safety Strap Included with the Roadmaster Stowmaster Tow Bar
    The original Stowmaster tow bar came with a safety strap. The tow bar has been updated and they have done away with the strap. The description currently on the site is being updated as well and references to the strap will be removed. The strap in question is no longer available by itself since you are supposed to use safety cables such as # RM-645 and since the base plates for vehicles started including the shorter cables that go from the base plates to the vehicle frame.

  • Can the Roadmaster # RM-645 Safety Cables Be Installed with the Hooks on the Base Plate Side
    If you have the room on your base plates connection to securely attach the hook, then there will be no issue with using the Roadmaster # RM-645 Safety Hooks. I found another option for you. The Roadmaster 64 Inch Double Hook Safety Cables, # RM-646, is the better option for you. Theses cables have the same features as the # RM-645 cables that you referenced, but this set includes hooks with spring loaded latches on both ends of the safety cable. These cable will make connecting and disconnecting...

  • Straight or Coiled Cables for Falcon All-Terrain Tow Bar?
    Because this tow bar has a built-in cable guide, I would go with the straight cables, part RM-645. The coiled cables might be a little hard to thread through the cable guide.
    view full answer...
  • Recommended Safety Cable Extensions When Rise or Drop is Required for Level Flat Towing
    If you need to add just a little more length to safety cables like # RM-645 due to a high-low adapter, I recommend using the safety cable extensions. Based on your current cable capacity, we have the 10 inch # RM-650648-10 extensions. For a 4 inch drop these extensions will allow a little slack to meet your needs.

  • 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.

  • Recommended Straight Safety Cables For Roadmaster Falcon Tow Bar With Enclosed Cable Guides
    Since the guides on the Roadmaster Falcon Tow Bar # RM-522 are enclosed, I would go with straight cables. The coiled may have a tendency to want to coil up and that would not work with the Falcon. The cables I recommend are part # RM-645. These are 64-inch long straight cables and will work well with the Falcon tow bar.

  • Coiled or Straight Safety Cables for Roadmaster Falcon All Terrain Tow Bar
    In general people tend to like the coiled safely cables like # RM-643 more simply because the design helps to keep the extra slack from hanging lower towards the ground or getting tangled on something. With that being said when it comes to tow bars like the Roadmaster Falcon All Terrain # RM-522 that you referenced, which feature integrated cable channels, straight safety cables are the better option. Straight cables like # RM-645 are just going to provide easier installation when feeding...

  • Safety Cables for a Roadmaster Falcon Tow Bar
    The Falcon tow bar, # RM-522, has a channel to run the safety cables through so you will want to use straight safety cables like the 64 inch Single Hook, Straight Safety Cables, # RM-645. Safety cables are not included and must be purchased separately. We also have a towing combo kit, # RM-9243-1, that includes the safety cables and accessories needed for the RM-522 Falcon tow bar.

  • Proper Safety Cables to Use with the Roadmaster Direct-Connect Base Plate
    I spoke with Roadmaster to help with this, and we have a solution. The EZ Hook Safety Cables, part # RM-655, are not compatible with the Direct-Connect Base Plate Kit for the 2020 Chevrolet Traverse, part # RM-523200-5. The Base Plate you have does not have a spot for the anchors of the cables to mount to. Instead, use the Single Hook Cables, part # RM-645. I've linked to a video installation of these cables so you can see how they work.

  • Tow Bar, Base Plates and Accessories Needed to Flat Tow 2001 Honda CRV
    The Roadmaster # 1528-3 base plates and the Falcon 2 tow bar would both work very well with your 2001 Honda CRV. You will also need safety cables which are not included with the tow bar, like part # RM-645. The Falcon 2 actually has guides built into it to keep the cables from being tangled or damaged. You will also need a wiring solution so that the tail lights on the CRV work in tandem with those of the RV. The Roadmaster Bulb and Socket Kit, part # RM-155 is an easy to use and install...

In my research, I found that the Fit is capable of being flat towed without modification, but you will want to consult the owners manual and follow the recommendations listed under the Recreational Towing section. You will also need a tow bar, safety cables, a lighting solution and a supplemental braking system to flat tow your Fit. The Roadmaster...

I am not sure what you mean by the forks . . . are you referring to the removable draw bars that the tow bar quick disconnects would attach to?
