• Avoid all sharp edges.
• Use shackles of an appropriate strength for the rope and consider switching to soft shackles for increased safety.
• Always check the splice before and during attachment to each vehicle
• Test before use. Try light pulls to test attachment before pulling at maximum force
• Keep spectators out of the tow zone
• A Bowline knot is recommended if the rope must be knotted. This will undo most easily after use.
*A knot can reduce a rope’s strength by as much as half.*
This is only a guideline. Use common sense and ALWAYS KEEP SAFETY THE TOP PRIORITY and ensure your application is verified for proper sizing prior to use. Remember knots in a rope or the use of a nylon rope while it is wet will have a negative impact on the rope’s strength. For more information on rope safety, read our Brief Note on Rope Usage & Safety.
