Q: How tight should I run my tarp?

A: There are several ways to tell if your tarp is tight enough... You should SEE the crank arm bow slightly, approximately 1/2”. You should FEEL approximately 40 to 60 pounds of pressure when placing the arm into the retainer. You will HEAR the tarp creak as it tightens under the latch plate. Where the tarp TOUCHES the end caps there needs to be a good seal and no flapping should occur.

Q: How can I prolong the life of my tarp?

A: By making sure the proper tension is applied to your tarp and that it doesn't flap and flutter in the wind. It is easy to adjust the tarp tension by taking the pin out of U-joint there are 21 adjustments to keep your tarp tight, a slight adjustment to the right or left will do it.

Q: Why is the end plug coming out of the roll tube?

A: There is a small screw that goes into the side of the roll tube and through the plastic end plug to hold it in place. This is such a tiny screw that sometimes it gets overlooked during the installation process.

Q: How do I replace the stretch rope in my Front Roll Return?

A: You will be removing the return assembly from inside the roll tube. Remove the old cord and insert new cord through PVC tubes, washer, and secure with a knot. Slide assembly back into the roll tube, secure end plug with screw. Slide protective cover on cord and slide cord through eyebolt. Let tarp hang over the edge of box, remove slack in cord. Just as tube begins to lift, tie a knot in the cord at that point through the eyebolt. For detailed information, download the installation sheet under the support tab, download the Front Roll Return (Bungee Cord).

Q: How long does the bungee cord need to be to go into the roll tube?

A: 11 1/2 feet for most applications, X-Wide kits are 16 1/2 feet.

Q: Why does my stretch rope not return in the cold weather?

A: Stretch rope loses its memory in colder climates; once the weather warms up, the stretch cord will regain its elasticity. If you are using the Shur-Lok^® system in colder climates consider upgrading your Shur-Lok^® return with a Shur-Return or Cable Return System. The Shur-Return has a lifetime warranty.

Q: Why are my bows wearing out my tarp?

A: There could be a couple of reasons, the first is not having enough tension applied to the tarp when it is in the latched position. You should SEE the crank arm bow slightly - approximately 1/2”. You should FEEL approximately 40 to 60 pounds of pressure when placing the arm into the retainer. You will HEAR the tarp creak as it tightens under the latch plate. Where the tarp TOUCHES the end caps there needs to be a good seal and no flapping should occur. The second reason is that one bow maybe setting higher than the rest of the bows focusing more of the roll tube weight on that particular bow. This additional weight, during the rolling process, may cause the tarp to wear quicker over that bow as a result.

Q: Why does my tarp fall in on the end caps?

A: Your tarp can fall into the box for a couple of reasons. First, make sure you are using some type of ridge support and it is installed over the top of the bows. If you have fabric caps, it should lie over the first bow of fabric cap, then under the cap and attached to the box. In grain cart and farm truck applications, you need to make sure that the first bow in from the end caps is installed no more than 30” for optimum performance.
