FYI, my truck has a sprayed in liner and this sticks to that work no separation. **Q: Is this roc block 4" or 7" in width?** A: My truck's in the garage, and I can't open the tailgate with the overhead door closed. What I can see of the Roc Block is appx. 2" along wide the top of the bed (can't see the portion along the tailgate). Must assume that the product I purchased is appx. 4" wide. **Q: does this kit come with the Adhesion promoter** A: It comes with alcohol swabs to clean both sides of the adhesion area. I put mine on almost two years ago and it is still adhering well following heavy use throughout this time. I am very pleased with it. **Q: Do I need standard 4" or XL for a 2020 f150?** A: The 4.25" width ROK BLOCK is best for all Ford trucks. Use 7" width ROK BLOCLK XL for 2021 and newer Ford trucks with a hinge retainer bracket, Ford Ranger and Ford Maverick (search ASIN: B076NFYH2R) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***R on January 22, 2026* This stuff works as advertised, the dust in my bed is virtually nonexistent now.
