## Questions & Answers

**Q: How long is the 4.25 tape?**
A: I do not know how long it is; however, I did my F-150 tailgate and have about 14 inches left over.  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)
