Installing or replacing a closing loop is an important part of safely packing a main canopy, but unfortunately is something that often doesn't get a great deal of attention.

Who?

The person packing the equipment and the owner both have a responsibility to ensure that the kit is safe to jump, which includes changing the closing loop when required. No advanced packing ratings are required to change a closing loop, this can be done by anyone suitably trained (e.g. packing certificate).

When?

Closing loops should be replaced at the first sign of wear. The USPA dictates that no more than 10% wear is acceptable. If you're looking at your loop wondering whether or not it needs replacing, then it needs replacing!

Why?

A loose or damaged closing loop risks a premature deployment - a very undesirable situation in the aircraft, in freefall, and especially whilst climbing out the door. Is it really worth pushing a £2 closing loop for an extra few jumps at the risk of taking down the entire aircraft?

How?

1. Remove your old loop from your rig. Depending on the container design, you may want to leave one end of a pullup in to make it easier to get the new loop back through the grommet.

2. Ensure you have a smooth washer with the correct size hole. If one side of the washer is smoother inside the hole, put this on the top (i.e. the side with the loop) where there will be more movement.

3. Tie a knot in your new loop to make it approximately 5-10% shorter than your old loop (the loop will stretch). Check that the loose end below the knot has the fingertrapped line inside (i.e. check that the knot is tying part of the fingertrap).

4. Put the loop back in your container and continue packing.

Always check the manual for your container for the correct closing loop length and routing.

Below are some loops and washers we've found in people's kit.

This closing loop should have been changed a LONG time before this was spotted.	There is a fair amount of wear on this loop and it should be changed immediately. Can you see the first signs of wear near the knot too?	The closing loop is in good condition. The washer on the left is what we recommend; the hole is just big enough to allow the loop material through, but too small for the knot. The smaller washer on the right is more flimsy and could bend. The hole is too big meaning the knot could be pulled through, and there's more room for movement which could cause damange by the knot.	This washer has a rough metal edge which would cause some serious damage to the closing loop and likely the container itself.
