Common Issues Users Have Faced


1) It’s Almost Impossible to Install the Undercover Armor Flex Over the Truck Bed by Myself!

The Undercover Armor Flex cover wasn’t designed to be installed by one person.

Note, you can’t install the cover all by yourself, so don’t even try to do it! You may find it easier to install the cover faster if you do the following:

  • Familiarize yourself with all of the instructions before you begin the installation job
  • Ask someone else to help you – remember that four hands are better than two for jobs like these
  • Make sure that the cover locks exactly as the instructions say they should. You may find water leaking into your truck bed during bad weather if you don’t!
  • Make sure to fit the cover over the bed properly and tightly screw the screws in place before you lock the cover in place over the bed!
  • Do a test drive of your cover to make sure that it fits properly. There’s nothing more frustrating than having leaking water ruin your LCD plasma TV!

    Pro Tip:  it helps if you clean the edges of the truck bed with rubbing alcohol before sealing the cover with heavy-duty tape!

Undercover Armor Flex covers are water-resistant and not waterproof


  • The cover is water-resistant and not waterproof. Minimize water damage by doing the following:
  • Install the cover properly and make sure that there are no gaps or overlaps in it. You’ll have rainwater seeping into it if that’s not the case!
  • Place drains and hinge areas in places where they can drain water away from the cover. Also, make sure that hinge areas have tight seals.
  • Make sure your gutters and seams are clean and free from debris. You run the risk of water seeping into your cover and ruining your cargo if that’s not the case!

    Pro tip:  you can use water-resistant seals and drain tubes on the sides of the cover to make the cover waterproof by draining off excess rainwater!

Solution:  pull every cable latch from the cover. Doing so will release the cover from its rails!

5) The Prop Rod Doesn’t Always Function as It’s Supposed To


the holes in the screws can come out with usage and time. It’s impossible to reattach the screws when that happens.

Solution:  you will have to use bigger screws and some strong glue to the screws and rods to secure the rods in place.

Pro Tip:  use a strong glue like Gorilla glue to secure the screws and rods in place.


4) It Takes a Ph.D. to Understand the Instruction Manual


Reason:  the Chinese made the Instruction manual. Any instruction manual that the Chinese make will be hard to understand since they only include a few hard-to-understand instructions and vague images!
