Product Description
The Roadmaster 643-2 is a pair of coiled tow bar safety cables rated at 6,000 lb, with a snap hook on both ends of each cable. Safety cables are the backup connection between the motorhome and the towed vehicle: if the tow bar ever separates, they keep the vehicles connected. Safety cables or chains are required by law for most towing systems.
These 68-inch cables are made from aircraft-grade galvanized wire rope with a vinyl coating that helps protect the tow bar's finish and your hands. The drop-forged steel hooks have spring-loaded latches, and the coiled design contracts for storage so the cables don't drag or tangle. The double-hook style makes the cables easy to attach and remove at both ends.

Pro tipTow bar setup tips
- Rating first. The tow bar’s capacity must be higher than your towed vehicle’s loaded weight.
- Keep it close to level. Tow bar makers specify how far the motorhome hitch and the base plate connection can be apart in height — use a rise or drop receiver to bring them in range (see your tow bar’s instructions).
- Check base plate compatibility. Different brands connect differently; mixing brands requires the right adapter.
