Spray in bed liners are fully compatible with the Tectonic Fold-Up cover. Peragon will not guarantee fitment with plastic bed liners with our Tectonic cover. The information below will explain what may need to be modified on your plastic bed liner in order for the Tectonic cover to install. Please note that based on your specific plastic bed liner that other modifications may be required that are not shown.
Bulkhead Modifications
The plastic that overlaps the top of your bulkhead would need to be modified as shown.
The Tectonic side rails have a tab (reference red arrow) that rests against the front of the bulkhead. Plastic bed liners would need to be cut out in the corners to allow for the rails to be set front to back.
Bed Side Modifications
Plastic bed liners may need to be altered at clamp locations. Below are photos of clamp locations for various models.
