How to Thread an Over Center Buckle Strap

1-3/4" Over Center Buckle
2″ Over Center Buckle

An over center buckle is an excellent tool to use for jobs that required a quick cinch. While less common than ratchet straps and cam buckle straps, an over center buckle is easy to use, and the latch mechanism creates less wear on the strap itself. The design also allows the webbing to create a layer of padding between the buckle and the cargo.

Constructed of a one piece base and lever arm, webbing is wound through the assembly. With the fastener in an open position, the user can feed the excess webbing through the assembly. Once slack is removed, closing the fastener will add tension to the webbing and hold it in place.

Because over the center buckles are slightly more complex to thread than a typical cam buckle, we’ve created a how-to video demonstration:

Cargo Nets for Trailers

Cargo nets for trailers makes securing cargo easy, safe, and quick.

• One-piece design eliminates the need for multiple straps, ropes, or bungee cords. Built-in spring fittings for E-track (not included; sold separately) make attaching fast and secure.

• The 41″ x 80″ size is generous enough to cover cargo but the low profile of the cargo nets industrial grade 2″ polyester webbing makes it easy to store when not in use.

• Adjusts from 92″ to 103″.

Two methods of tightening are available for cargo nets from US Cargo Control: ratchets or cam buckles:

  • A cargo net with ratchets allow you to create maximum tension on the straps to keep the cargo net tight.
  •  Cam buckles makes adjusting the net quicker, but do not provide as much tension as ratchets do since desired tightness is achieved only by your own strength of pulling the loop end.
  • Cam buckles are a good choice for more fragile or lightweight cargo to -avoid the risk of over tightening, while ratchets are ideal for durable and/or heavy items that require tension to keep secure.

How to Thread Ratchet Straps and Cam Buckle Straps

While both ratchet straps and cam buckle straps are used to haul various types of cargo and come in sizes ranging from 1″ to 4″ in width, there are some key differences between the two.

Ratchet straps

A ratchet strap is available with many different fittings: chain extension, d-ring, e-track fitting, e-track double stud fitting, f-track hook and spring e-fitting, flat hook, flat snap hook, j-hook with d-ring, s-hook and vinyl coated wire hook.

Polyester webbing is most often used for both ratchet straps and cam buckle straps because it has a low stretch rate and is very resistant to abrasion.

How to thread a ratchet strap

1.) Open the ratchet so you have access to the take-up spool.

2.) Slide strap through the spool and bring it right back on itself.

3.) Pull on the strap to remove the excess slack.

4.) Once the slack is removed, you can start to ratchet the strap to the desired tension, keeping the strap straight.

5.) Once you have reached your desired tension, lock the ratchet down to its closed position.

To release the strap, open the ratchet all the way so it is completely flat and pull the strap out.

In cases where you do not need the strength of a ratchet strap, a cam buckle is an excellent choice. Cam straps are also available with various types of attachment hardware: butterfly fitting, e-track fitting, F-track hook and spring e-fitting, handle bar strap with S-hook, flat snap hook and s-hook.

Cam buckle straps 

Cam buckle straps typically come in 1″ and 2″ sizes. This video highlights the differences between ratchet straps and cam buckles and also shows how to thread a cam buckle.

How to thread a cam buckle strap

1.) Turn the cam buckle over and thread your strap back through  while pressing the thumb release.

2.) While pressing the thumb release, pull the strap to your desired tension and then release.

To release the strap, press the thumb button and simply pull the strap.

In choosing between a ratchet strap and a cam buckle, it generally depends on work load limit or how fragile the product is that you are securing. If the cargo is light and fragile, go with a cam buckle since you cannot run the risk of over-tightening and crushing the product. For items heavier or more sturdy, a ratchet strap is a good choice.

How to Thread a Toothless Cam Buckle

Cam buckles can be confusing to thread webbing onto for the first time. This video explains the proper procedure for feeding webbing onto a 1″ toothless cam buckle. Cam buckles come in all different sizes, so make sure the strength of your buckle is appropriate for the item you are securing. US Cargo Control shows you the right way to thread a strap through the buckle.

Threading a toothless cam buckle involves 4 basic steps:

  1. Open the buckle and feed the webbing between the guides.
  2. Loop the webbing back through the buckle.
  3. Next, feed the webbing through the slot in the mandrel and pull it tight.
  4. Close the buckle, and now the webbing is in place.
