It effectively blocks dust, water, and fumes from entering the truck bed through the tailgate gap and sidewalls, using automotive-grade 3M ST1200 tape for a secure, weatherproof installation. Ideal for truck owners who use bed caps or tonneau covers but occasionally haul loose materials, this USA-made product reduces clean-up time and protects cargo space with a durable 4.25 inch thick, 5.5 feet long seal. ## Description If you have a truck bed cap or tonneau cover and want to keep out dust and water from your truck bed but occasionally use your truck for transporting loose material, then this is the solution. FITS: RAM 1500 (standard tailgate), Ford F Series without a hinge retainer bracket (see image), Chevy Colorado, GMC Canyon, Nissan Titan, Jeep Gladiator, Toyota Tacoma, Toyota Tundra and Silverado EV with Standard Tailgate. See ESI ROK BLOCK XL for other trucks (search ASIN: B075PWVW67). Both EPDM rubber seals eliminate dust, fumes and water from entering through the tailgate bottom gap and sidewalls when using a truck bed cap or tonneau cover. Adheres to all surfaces including spray on bed liners. The original and patented Tailgate Gap Cover ROK BLOCK installs over the tailgate bottom gap and eliminates debris from falling into the gap, greatly reducing clean-up time when hauling material. Doubles as a tailgate seal for the tailgate bottom gap. For a drop in bed floor liner, ROK BLOCK installs under the liner. The original and patented Ultimate Tailgate Seal with Taper Seal installs on the sidewalls. Packaged directions and online instructions must be followed to properly install this product. Apply when the air and surface temperature is between 55° - 104°F (13° - 40°C). Both seals adhere using high quality, automotive grade 3M ST1200 tape. MADE IN USA. Excluded trucks (6) for both ROK BLOCK and ROK BLOCK XL: Ford with Pro Access Tailgate, Honda Ridgeline with Dual Action Tailgate, Hyundai Santa Cruz, RAM with Multifunction Tailgate, Rivian, and Tesla Cybertruck. Review: Tailgate tape - I love my Ram truck but the gravel dust was ridiculous! Followed the directions and easy install. It works great and no gravel dust! Review: Great product - This stuff works as advertised, the dust in my bed is virtually nonexistent now. Installation was easy, and the tape sticks like crazy, so lay it down right the first time, because it's not coming off! ## Features - If you have a truck bed cap or tonneau cover and want to keep out dust and water from your truck bed but occasionally use your truck for transporting loose material, then this is the solution. - FITS: RAM 1500 (standard tailgate), Ford F Series without a hinge retainer bracket (see image), Chevy Colorado, GMC Canyon, Nissan Titan, Jeep Gladiator, Toyota Tacoma, Toyota Tundra and Silverado EV with Standard Tailgate.

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 ### ⭐⭐⭐⭐⭐ Tailgate tape *by S***K on May 24, 2026* I love my Ram truck but the gravel dust was ridiculous! Followed the directions and easy install. It works great and no gravel dust! ### ⭐⭐⭐⭐⭐ Great product *by J***R on January 22, 2026* This stuff works as advertised, the dust in my bed is virtually nonexistent now. Installation was easy, and the tape sticks like crazy, so lay it down right the first time, because it's not coming off! ### ⭐⭐⭐⭐ Great product *by T***R on July 12, 2026* Purchased for 2024 Jeep gladiator. The tailgate gap filler is great. Easy to install and has stayed in place. The weather stripping for the side of the tailgate has been good. I wish the adhesive from the gap filler was on the weather stripping. The smaller pieces at the top of tailgate are not staying in place. I think the better adhesive would help. ## Frequently Bought Together - ESI ROK Block 4.25 inch Width Tailgate Gap Cover and Ultimate Tailgate Seal with Taper Seal 6ft for Sidewalls - XFasten Butyl Tape Black, 1/2 in x 30 ft x 1/8 in – Easy-to-Work-with Automotive Butyl Sealant Tape, Mess-Free Rubber Caulk for RV, EPDM Putty for Window, Headlight, Roof, Windshield, and Car Doors - ESI Ultimate Tailgate Seal with Taper Seal 10ft for use with Truck Caps and Tonneau Covers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/17490175-esi-rok-block-4-25-inch-tailgate-gap-cover-ultimate](https://www.desertcart.com.pa/products/17490175-esi-rok-block-4-25-inch-tailgate-gap-cover-ultimate) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-07-21*
