  • Hybrid coiled-to-straight cables expand and contract for a cleaner look with extra length
    • Coiled end prevents cord from dragging and tangling

  • Length: 80"
  • Capacity: 8,000 lbs
  • 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.

Easy install. Replaced my damaged cables in about 15 minutes. Well made cables.

Good quality, works well

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

Just what I was needing

I have a motorcycle on the back of my RV and these cables are what I needed.

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


by:

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



by:

Excellent fast service.



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:

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:

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 !



by:

What can I say? These cables were purchased as replacements. The came quickly and worked as expected.

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



by:

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



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:

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:

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



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.



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!

Working with the folks at etrailer was just fantastic. All of them were very helpful and really knew their products.

I am sorry that the safety cables are not working with the channel guides on your Sterling tow bar. I reached out to Roadmaster and they advised that some of the older models have a smaller channel as so the loops will not fit through. The only solution I have would be to use a coiled cable like part # RM-653 that would not use the tow bar channel and keep the cables from hanging too low.



by:

this is an excellent choice for cables. the coil allows you to have expansion with out dragging your cable on the road and still have plenty of reach.

    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...

  • Can 2017 Toyota Tacoma TRD Be Flat Towed
    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.
