Ever worried that your primary knot might come undone when you need it most?
That’s where the backup knot steps in!
If your primary knot starts to slip or untie, the backup knot stops the end of the rope from slipping through.
Let’s look at what makes it useful and when you should actually use it.
Why Use a Backup Knot?
It’s all about safety.
If you’re climbing, doing rope rescue, or in any situation where your life depends on a knot holding strong, you need a backup knot.
It acts as an extra layer of security in case the main knot fails.
Some of the most used stopper knots are:
Among these, we will focus on the Fisherman’s knot only, as it is the widely used to backup the Figure 8 follow through loop.
How to Tie the Fisherman’s Knot (Half Double Fisherman’s Backup)
The Half Double Fisherman’s Knot is the most common choice for a backup.
It’s easy to tie and creates a reliable stopper that stays put.
Let’s see how you tie it:
- Wrap the working end twice around the standing part of the rope, working back toward the primary knot.
- Feed the working end through the loops.
- Hold the primary knot and pull the working end to tighten the knot.
You have done it correctly if you notice an X on one side and two parallel lines on the other.
Do You Always Need a Backup Knot?
So, the big question that always sparks debate:
Do you really need one every time?
The short answer: No.
Take the Figure Eight Follow Through knot, for example. It’s already strong and secure on its own when tied and dressed properly.
Adding a backup knot does not make the knot stronger. It can complicate the process and make visual inspections more difficult.
Some climbers and gyms still prefer tying the backup knot, not because the primary knot is weak, but because it gives peace of mind.
The thing is, instead of relying on backup knots, climbers should focus on tying the perfect primary knot and performing thorough partner checks.
Other Backup Knots You Might See
Overhand Knot
The Overhand knot is the simplest stopper knot.
It’s tied at the end of the rope and prevents the rope from sliding through the main knot.
Although not very common, it still shows up as a backup to the Figure Eight Follow Through knot.
Barrel Knot
The Barrel knot is a more secure backup knot.
It can be used as a stopper knot on a rope or a backup knot for a belay device.
But it requires some dexterity to tie this knot correctly.
What About Bowline with Yosemite Finish? Is It Secure?
The Bowline is quick to tie and untie, but it can loosen under repeated movement and cyclic loading.
That’s why the Yosemite backup exists.
It’s tied with the working end wrapped around one leg of the loop and tucked back through the knot.
This finish makes it easier to untie after a load and prevents the knot from capsizing.
Just be careful: If you tie it wrong, it can capsize and fail completely. ALWAYS dress the knot before putting your weight to it.
