When Not to Use a Square Knot

Square knots are not your best choice when you have two different thicknesses you wish to join. They slip when you tie them with a nylon rope and will also slip if it is not under tension.

Critical Tip:

Square knots can be dangerous if misused and should never be used in critical situations where lives might be at risk. This is simply due to the potential instability of the knot.

Unfortunately, many accidents took place as a result of trying to join two ropes with a square knot.

Step-by-Step Tutorial

Pay close attention to these steps, as a square knot is often tied wrong. You will end up with a “granny knot,” which may slip under a heavy load.

See how this type of knot looks like or tied by using two colors of cord.

Step 1:

Remember: “Right over left, left over right.”

Step 2:

Take one line in your right hand, and one in your left and lay the right over the left.

Step 3:

Pass the right end over the left end and back under the left.

Step 4:

Pass the left end over the right end and back under the right.

Step 5:

Check the knot (the two loops should slide on each other).

Step 6:

Tighten by pulling both strands on each side of the knot.

Step 7:

Create a backup knot by making an overhand knot on the shorter ends of the rope.

Step 8:

Backing up a knot is important so that the square knot will not untie itself.
