Kevlok Tie-Downs & Tie-Down Straps

Tie-downs, (or tie-down straps), secure products and equipment in place during transport or while in storage.

What are tie-downs?

Tie-downs also referred to as tie-down straps, are a length of webbing that is tensioned and used to secure cargo or equipment for transportation. This webbing can be secured in different ways using different types of tie-down hooks, buckles, or anchor plates.

Frequently Asked Questions

1. How short can I make the fixed/adjustable end of the strap?

This is dependent on the type of hardware that is selected. Generally speaking, our sewing machines need a minimum of 2-1/2″ between hardware fittings for the “foot” of the machine to sit flat on the webbing. We measure our straps from the center of the pivot point on the buckle to the center of the fastening point on the end of the strap.

As an example, one of our most commonly purchased over-center buckles, the K413, has a length of 1.25″ from the pivot point to the tip of the buckle. Our K480 anchor plate has a length of 1.25″ from the center of the bolt hole to the edge of the buckle. Therefore, the shortest fixed end that we can make using a K413 over-center buckle and a K480 anchor plate is 1.25″ + 1.25″ + 2.50″ = 5.00″. As you can see, if we added a quick disconnect, say a K460, this will add the full length of the K460, or + 1.36″, making the shortest fixed end of a K413 with a K480 and a K460 equal to 6.36″.

2. Can I use this strap in saltwater, around battery acid, or in gasoline? Will that be ok?

This is determined by the material of the strap, and the material being exposed to the strap. Our straps are made from nylon, polyester, or polypropylene webbing. There is no simple answer to this question, please contact our engineering department for help with material selection.

3. How much will the straps stretch?

This is largely determined by the test method used to evaluate the stretch. In general, the nylon webbing will stretch between 20% and 30% and polyester webbing will stretch between 15% and 25%.

These are general figures and depend not only on the test method but also on the environment: temperature, humidity, age, and other adverse conditions. Please contact our Engineering Department to inquire about your specific application.

4. How do I thread the over-center buckle?

5. How do I thread the cam buckle?

6. How do I thread the ratchet buckle?

7. What is the hardware finish?

Most of our hardware is steel and is finished with a zinc plate with bronze chromate coloration. It is service condition 3 for good corrosion resistance.

We also have select items in stainless steel. The stainless steel items are either bare or have been passivated.

8. How long can my strap be?

The strap can be as long as you would like it to be. However, when using over-center buckles we do not recommend lengths over 18 feet for 1″ webbing or 30 feet for the 1-3/4″ webbing. This is because the over-center buckles rely upon tension in the strap to stay fastened.

Since the webbing has significant stretch properties, longer straps can be temporarily loaded in such a way that the over-center buckle can be released.

9. How strong will the strap be? How much weight will it hold?

This usually depends on the hardware that is selected. Hardware is rated with breaking strength and a working load which is usually 1/3 of the breaking strength. You should select strap hardware based on working load, not breaking strength. Frequently, if the load applied approaches the breaking strength, the hardware will be damaged due to mechanical deformation, even if it does not break. If sufficiently strong hardware is selected, then the stitching on the webbing becomes the next weakest link.

10. What webbing do you supply?

We supply nylon, bulked nylon, polyester, and polypropylene webbing in a variety of sizes and colors. See our complete range of webbing products.

11. What color webbing is available?

There is a wide range of colors available in our most common webbing. Colors include black, olive drab, red, blue, gray, orange, yellow, green, and brown. However, it is a good idea to check the availability of any given webbing color.

12. Do you make custom straps?

Yes, we will make straps to meet your drawings or to meet our own internal drawings. Contact us for more information.

13. What tie-down hardware do you supply?

We have a wide array of tie-down hardware, including over-center buckles, cam buckles, ratchet buckles, d-rings, threading plates, and more.
