The Jam Hitch is a binding knot used to secure bundles, sticks, gears, or even used as a replacement for Zip Ties.
It looks similar to the Tautline Hitch in structure, but it works differently.
Instead of wrapping the rope on the inside first, it starts with the initial two wraps on the outside of the working line. Then, you finish it off with one wrap on the inside.
This final wrap is what gives it grip, so it stays jammed tight and does not open.
Let’s learn it in detail.
Jam Hitch Details
Type: Hitch
Other Names: Adjustable Jam Hitch
ABoK Reference: #1727
How to Tie a Jam Hitch Knot
- Wrap the rope around the object.
- Make a round turn (two full turns) around the standing line of the rope.
- Tie another turn above those turns in the same direction.
- Slide and tighten the knot.
The knot will cinch in when you pull the standing part of the rope, and it stays put unless you need to loosen it.
Application and Uses
- Bundle sticks and poles
- Securing rolled up blankets, mats, and tarps
- It can be used as a replacement for the Zip ties in an emergency.
Pros & Cons
- Grips tightly. No slipping.
- Easy to tie if you know the Tautline Hitch.
- Closes easily and does not tend to open.
- Difficult to untie after use (maybe a pro or a con depending on the use)
- Hard to adjust once cinched down.
Canadian Jam Knot
Now, if you want something with a bit less bite, Canadian Jam Knot is your go to.
It’s a simple Noose knot. It tightens down and grips harder as you pull.
But it does not cinch down as hard as the Jam Hitch and is comparatively easy to open afterwards.
This makes it a perfect choice for bushcraft and camping activities where you need to secure the item temporarily and untie it after a long day.
Other Jam Hitch Types
Ashley had a few things to say about the Jam Hitch (or knots).
He mentioned that there are several forms of Jam Hitch. One of them is the Buntline Hitch, which he says “serves well as a JAM KNOT.”
So it’s no wonder you have multiple entries of Jam Hitch in the Ashley Book of Knots.
Here are three more “JAM” knots with knowing:
- JAM Knot (ABoK #1228): This functions like a Noose. Once drawn up, it does not open up quite easily. Don’t expect to untie it fast.
- JAM Hitch (ABoK #1991): This variation can be slid up and down the standing line while adjusting.
- Jamming Hitch (ABoK #1992): This functions similarly to ABoK #1991.
Then, it is jammed by pulling the tag end.
