How To Use a Ratchet Strap

We use ratchet straps all the time in the 4x4 world and out of it - securing canoes and kayaks, lashing lumber, clamping steel for fab work, and kludging together trail breakage.

As common as they are, ratchet straps are pretty confusing to use for some people and may have a feature or two you didn't know about.

Also:

We see people flying down the highway all the time without the ratchet locked!

So here are a few tips on using ratchet straps and releasing ratchet straps when they get stuck.

Ratchet Strap Basics

Ratchet Mechanism of a Ratchet Strap
At least one of the pawls is engaged when tightening. Neither pawl is engaged in loosening.

All ratchet straps work the same way using a ratchet mechanism.

But while a typical ratchet mechanism uses a gear and a single pawl, a ratchet strap uses:

  • a gear
  • a manual pawl  - you move it
  • an automatic pawl - it moves itself

Ratchet Strap Pawls
One pawl has a handle (for you), the other moves by itself.

When you tighten a ratchet strap, at least one of the pawls is engaged with the gear teeth.

When you loosen a ratchet strap, neither pawl is engaged. So, when a ratchet strap is stuck, usually you just haven't disengaged the pawls. More on that below.

The 3 Important Ratchet Strap Postions

Ratchet straps are generally in one of these positions:

  1. Ratcheting - You can tighten it.
  2. Loosening - The ratchet is spread all the way open until the auto pawl rests on the cam. To loosen, you squeeze the manual pawl and pull the strap.
  3. Locked - When it's tight, close the ratchet completely and make sure auto and manual pawls engage. This will keep it from opening.
Ratchet Strap Ready to Tighten
In this position you can move the handle back and forth to tighten the strap.
Ratchet Strap Locked for Travel
The auto pawl (blue) and manual pawl (pink) both engage the ratchet gears when the mechanism is completely closed. This is the position it should be in for travel!
Ratchet Strap Loosening Position
When the auto pawl (blue) is disengaged from the gears by the hump (green), you can squeeze the manual pawl and loosen the strap.

To get the ratchet into these positions, you need to either squeeze the manual pawl handle or swing the bar.

Ratchet Strap Actions
You can: 1) Squeeze the manual pawl handle to disengage it from the gear. 2) Move the ratcheting bar back and forth.

A common ratchet strap problem is getting it to release. Usually, you just need to squeeze the manual pawl bar and keep making the ratchet flatter.

Compare the position of the blue pawl to the green hump in the images below.

This ratchet strap will not loosen!

 The blue pawl needs to be up on the hump. Squeeze the manual pawl handle and open the ratchet until it's completely flat!

This ratchet strap will loosen.

The ratchet is totally flat and the blue pawl is in the correct position.

How to Thread a Ratchet Strap

Threading the Ratchet Strap
Pass the strap end through the slot and pull it through.

An easy way to thread a ratchet strap is to visualize the "greater than" and "less than" signs with their points touching, like this: ><. To make this shape with the ratchet strap:

  1. Make the ratchet an angle (it only angles one way)
  2. Feed the strap through the axle and back out
Correct Ratchet Strap Threading
Notice the "greater than" (pink) and "less than" (green) signs made by the ratchet and strap ends. The hooks should end up on the same side.

How to Tighten a Ratchet Strap

To use the ratchet strap take all the above information and put it into practice:

1) Attach the hooks to secure points and position the strap.

Position the Ratchet Strap
Get the hooks secure.

2) Pull almost all the slack out of the strap so that the strap is taut. Sometimes we'll leave a little slack if the thing we're tightening doesn't have a lot of "give".

Pull Out the Slack
Grab the end without hooks and pull the slack out of it. It's okay to have a little slack, but too much will jam the ratchet.

3) Start ratcheting the bar up and down. Don't squeeze the manual pawl - you'll use it to release the ratchet strap later, but it needs to be able to move freely right now.

Ratchet the Bar
Move it up and down, tightening the strap.

4) Get it tight enough. Be careful not to damage the thing you're tightening against. Make sure your hooks haven't slipped!

Get It Tight
Make sure the strap that builds up on the axle doesn't get super fat, or the strap could jam.

5) "Close" the ratchet and lock the bar in position. In this position the auto pawl can't back out and the manual pawl acts like a failsafe. This is the only way to safely travel with your ratchet strap.

Lock the Ratchet Strap
Pull the handle down all the way. The manual pawl (pink) and auto pawl (blue) should go into position. In this position the ratchet strap is safe for travel.

How to Loosen a Ratchet Strap

If you have trouble loosening your ratchet strap, go up and take a look at the "loosening" position above. You can't loosen it if it isn't in that position!

1) The ratchet should be in the locked position. Get ready to squeeze the manual pawl.

Get ready
Get ready to squeeze the manual pawl.

2) Squeeze the manual pawl. This will unlock the ratchet - you still need to disengage the auto pawl.

Squeeze the Manual Pawl
This is the first part of unlocking the ratchet strap.

3) Keep squeezing the manual pawl and swing the bar up as far as you can. This won't work if you don't squeeze the manual pawl.

Unlock the Ratchet Strap
Continue to squeeze the manual pawl, and swing the bar up as far as possible.

4) Make sure the ratchet is completely flat. If you did it right, the strap will pop a little! If it didn't pop, then the auto pawl is still engaged.

Disengage BOTH pawls.
Make sure that you make the two halves nearly flat! When properly positioned, you won't be able to pull the handle back down - it will be locked in its flat position.

5) Pull the ratchet toward you to get slack. All done! Now you can pull the strap off.

Loosen the Ratchet Strap
Pull the ratchet strap towards you.
