  • Limited Lifetime Warranty


Roadmaster Safety Cable Hook

Heavy-duty safety cables ensure that your towed vehicle does not separate from your motorhome in the event that your tow bar becomes detached. Spring-loaded, drop-forged steel latches provide a secure connection while towing. A smooth vinyl coating prevents the cables from scratching or chipping your tow bar.


Roadmaster Hybrid Safety Cables

The hybrid, coiled-to-straight design will keep the cables off the ground. These cables are ideal for tow bars with safety channels, such as the Roadmaster Nighthawk tow bar (RM-676 - sold separately). Just remove the hooks and quick links from the straight ends and they'll fit neatly through your tow bar channel guides to attach to your towed vehicle. The coiled ends easily extend to your RV without dragging on the road.

I am very sorry to hear this Matt. Can you please respond back with the part number on your hitch? I would like to look into the brand as this is the first time I am hearing that they do not work on a class 5 hitch.

@KateF I have 2017 Entegra Cornerstone, which has a 20k LB tow capacity and a class 5 hitch. Being that the hooks on the spring end of the cables (molded end, they needed to be cut off and then add 3/8" hooks to connect.

@Keith Nice! Glad to hear your safety cables are still doing their job. Come back anytime you need anything!


by:

Works great. The hooks are a very tight fit for the "Roadmaster Direct-Connect Base Plate Kit - Removable Arms (Item # 921-3)" but you'll quickly learn the only way to get them attached. The cable fits very nicely within the carriage rail of the above base plate kit, so no need to fiddle with once setup correctly.



by:

Eyelets were too big to go through tunnel on the tow bar had to squish them so they would fit other than that good deal



by:

These cables fit perfectly through the channel on my tow bar because of the uncoiled section. The coiled section keeps the remainder of the cable tight so that it does not hang down.



by:

Products, excellent. Video and delivery, excellent. Alex, excellent!!



by:

I ordered towing safety for my Roadmaster tow bar, and once again E-trailer came thru with flying colors. Everything arrived on time and in good shape. Excellent quality parts packaged well and shipped immediately via UPS. Thank you Hannah !

Nothing new to add. The cable work as all safety cable should. Jut like all RoadMaster products.



by:

They work great, easy to hook and unhook. Hard to beat Roadmaster!



by:

Always have fast delivery as promised, better than [online store] for shipping times,
Thanks, needed them today.



by:

Exact replacement! Don’t cross the cables under the hitch. If the hitch drags the cables will scuff. No real damage to the cable, but the plastic coating was cut badly. Live and learn.



by:

We were always happy with our purchases and customers service with you's unfortunately we lost our 40 foot motor home and our tow car in hurricane Ian.But I'm sure we will be customers in the future thank you



by:

Product was just what I wanted and needed. More importantly, etrailer had it in stock at the right price. 3rd time I have done business with etrailer, and I am 100% satisfied. Look forward to future transactions!



by:

Helen at Etrailer was very helpful & friendly, this company is alway on top of there game no
matter who I talk to. If they do not stock something they always recommend where I can find what I am looking for.

Working with etrailer is always easy. Deliveries are on time and correct. Thanks.

  • Safety Cable Recommendation to Use with Roadmaster Falcon 3HD Tow Bar
    Hey Gary, the safety cables you would want to use with the Roadmaster Falcon 3HD part # RM27NQ that you referenced would be the hybrid set part # RM-674 which would allow you to use the safety cable guides on the tow bar. Do you have a base plate picked out for your vehicle already as well? If what you have is a 2023 Ram 1500 the base plate kit you'd want is the part # RM-522203-5.

    Hey Scott! It looks like your 2025 Bronco Badlands SAS comes with LED lights so for trailer wiring you can use the Curt T-Connector Vehicle Wiring Harness # C42WR. This plugs into the connection points behind your tail lights and will provide you with a 4-way to power your trailer lights. If you're looking for a 7-way, you need the Tekonsha OEM Replacement Vehicle Wiring Harness w Brake Controller Adapter # TK55VR instead.

    Hello Robert. I reached out to Roadmaster and they have not been able to test the Vevor tow bars with the Roadmaster Direct-Connect Base Plate Kit - Removable Arms # 131-8 so they cannot recommend using that tow bar with their baseplate. With that being said, I would recommend using a different tow bar. The Roadmaster Sterling All-Terrain Tow Bar - Non-Binding - RV Mount - 2" Hitch # RM-576, these tow bars are rated up to 8,000 lbs so they would work great for your 2022 GMC Sierra. If...

  • Trailer Hitch for 2024 Coachmen Mirada For Flat Towing 2023 Jeep Wrangler
    Hey Mike! More than likely the Curt Adjustable Trailer Hitch Receiver # C13701 is sufficient for flat towing your Jeep. It has a max gross trailer weight of 5,000 lbs so you will be able to tow any standard 2023 Wrangler. The only exception is if you have the Rubicon 392 or the 4xe which exceed the rating of the hitch. Do you have the rest of your flat tow setup picked out already? Where are you headed first once you get everything set up?

    Hey John! The answer in this case is yes and no. Officially, you cannot flat tow your 2017 Toyota Tacoma TRD. If you look in the owner's manual it states "Your vehicle is not designed to be dinghy towed (with 4 wheels on the ground) behind a motor home." However, base plate kits exist for the Tacoma which means enough people do it anyway. If you want to flat tow the vehicle and it is a manual you can put it in neutral, put the transfer case in 2WD, and accept the risks. For an automatic...

    No, it will not. Since your 2023 Ford F-150 has LED tail lights you will need the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights item # RM38FR. The issue is that the brake and running lights will all be the same brightness with the standard diodes included in the Demco item # DM9523010-54.
