Customizable Placement
Thanks to the strong suction cups, the Bumperninja Door Defender can be easily positioned anywhere on your car door, giving you the flexibility to protect the most vulnerable areas from potential damage.
so how do you install it?

step 1
After cleaning the area, position the Bumperninja Door Defender on the desired area of your car door. Make sure it's aligned with the door and centered on the area you want to protect.

step 2
Press the suction cups firmly onto the surface. Make sure they're securely attached and that they're positioned evenly on both sides.

step 3
Carefully press the Bumperninja Door Defender against the car door, making sure that it's securely attached. You should hear a satisfying "click" when it's attached properly.

step 4
Double-check the placement of the Door Defender to make sure it's positioned correctly and covers the vulnerable area you want to protect.
