The Easy Clips are designed to fit tightly on your tailgate to prevent slipping. However, if you cannot get them on your tailgate, there are a couple of things to check. First, ensure they are at the correct spot on your tailgate, Use the Clip Height Placement Tool that came with your billboard and measure from the bottom up. The bottom of the Easy Clip should align with the top of the Clip Height Placement Tool when the clip is placed in the correct spot. If the Easy Clips are in the right location but you can’t fully push them onto the tailgate, you will need to apply more pressure. One option is to take a rubber mallet and tap the clip into place. Remember, the Easy Clips should fit tightly, so don’t worry if a little bit of force is required to push them onto your tailgate. The combination of Protective Tape and no-scratch material inside the Easy Clips will ensure that your paint job will not get damaged.   ENSURE THE EASY CLIP IS PRESSED COMPLETELY ONTO THE TAILGATE. If the clip is not pushed completely onto the tailgate, closing the tailgate could damage the body of the truck.
