Soft tonneau covers are used to modify the looks of the trucks. A soft tonneau cover should be close fitting and tight. A loosely fitted soft tonneau cover can cause flapping on a windy day.

A soft tonneau cover needs more steps to tighten and adjust. Some steps need to be followed to maintain the cover tightness. It should be tight and effective so that it doesn’t flap. So Let’s see how to do that.

Rubber seals

The soft tonneau cover can be tri-fold or rolled up; it needs to be properly fitted. These two types are more prone to sag and get loose in the middle part.

Rubber seals can be used to seal the sides properly with an aluminum frame. The seal should be installed properly on all the edges of the truck. They will prevent the cover from flapping and keep it in position. Rubber seals or any other type of seals can be used.


Use aluminium clamps for providing support and easily accessible trunks. Clamps make the cover stay in place and keep it tight. They provide more stability to the tonneau cover.

Tighten clamps keep the cover in place so tighten the clamps when opening or closing the cover. Don’t over tighten the clamps, they can cause the braces to lose and break. clamps hold the cover down so over-tightening can cause the clamps to easily break or lose their grip.

Adjustable tension

To maintain a properly tight cover tension is provided so that a cover can have longer stability. The tension adjustable can be installed on the truck so it can easily be manageable and rolled to make the cover stay tight. Adjustable tensions can be rolled clockwise or anti-clockwise to make the cover stay in place.

Make sure to keep the adjustable tension similarly on both sides. The position and adjustment should be equal.


Soft tonneau covers are different from tonneau covers and they are prone to sulk in the middle part. To keep the middle part well and tight rails can be used. Railing provides a lot of time and struggle. The railings should be placed properly and in position.

This makes sure that the cover stays tight and reduces sulking. Also railing the seats to make sure there is no leaking. the seats should be put down to cover up all the edges.

Cover arrangement

The cover can be adjustable so it can be pulled and aligned from the edges. The fighting and proper fitting can be accomplished by applying this step.

This step will make sure the cover doesn’t flap and sulk or make noise from the wind. To make sure of that, start adjusting your cover from the top side to the corner sides. pull the sides evenly and then use clamps to position it properly. If needed add multiple amounts of clamps.

Weather sealing

Investing in a good quality material tonneau cover will make it look and stay fit for a longer period. Some soft tonneau covers don’t have sealants so make sure to install a cover that has it.

It can be helpful to stay the cover in place and reduce water damage. The weather changes can’t be able to cause much damage and the tonneau cover gives more durability.

Cleaning and testing

The new truck cover needs to get cleaned so it stays well. maintaining the parts, seat and clamps need to be maintained and checking and cleaning. Clean the cover with a cleaning treatment and wipe the surface dry. This step will prevent the surface from damage and dust.

The cover needs to stay well maintained so that it holds tightness. Test out whether the steps work or not by using these methods in the truck cover. If not using the truck keep checking and testing.


At the end of the day, the cover should stay in position and doesn’t cause flapping. To fix the cover properly take it to a professional so it doesn’t get over tight. If any part causes the problem with tightening then fix that part or replace the parts.

Only put the amount of tightness needed not more than that. These points must help the tonneau cover to stay properly tight.
