A waterproof tarp is essential for any open-bed truck, dump truck, or dump trailer. Without a waterproof tarp, exposure to rain, wind, and sunlight can adversely affect the vehicle and lead to damage to the cargo. Therefore, selecting the correct size is crucial.

How to obtain the required size for the waterproof cover:

Measure the width of the waterproof cover according to the width of the tarp roller.

To measure the width of the waterproof cover, kindly measure the tarp roller using a tape measure from one end to the other end of the front roller. This will provide us with the accurate data needed, but it's important to note that we need to subtract approximately 2.5 inches. This adjustment accounts for the width being about 3.5 millimeters less than the roller, ensuring even rolling and unfolding.

If you need to comply with local DOT standards, it is essential to choose our high-quality waterproof tarp with side flaps. This type of tarp, equipped with thick edges and locking rings all around, can assist you in securely fastening the waterproof tarp to your dump truck.

Determine the length of the waterproof tarp based on the unloading body:

Confirming the required length for the waterproof tarp is also a straightforward task. However, one point to note is that the length of the dump body or trailer needs to be increased by 2 feet. This has the benefit of allowing the waterproof tarp to cover the accumulated load when needed, especially in situations where partial overloading might occur.

Summary:

When calculating the width: Measure from both ends of the front axle/roller and then subtract 3.5 inches.

When calculating the length: Take the length of the truck body and add 2 feet. Be cautious not to add too much, as it could lead to a loose fit, causing instability during vehicle operation.
