After reading all the reviews, I bought this seal and it works well! It was installed 2 months ago and the adhesive REALLY sticks! An important point - it absolutely keeps water and dust out of the truck bed... but it also TRAPS water and dust IN the truck bed. Obviously. I've had a tonneau leak for some time before installing this seal, and now I'm extra motivated to stop that tonneau leak. As I said, this seal really sticks and works!

Excellent product

Reviewed in the United States on February 25, 2023

Verified Purchase

Very easy to install, about 20 minutes. Read and follow the instructions! Take your time and it will look like an OEM option. I have a bedcover and bed and anything in it fills with dust and this is a great way to stop that. After you apply the primer, do not make a mistake because it is stuck. Had the plain weather strip on my last truck and this is a much better option. Seems to be very high quality stuff. Installed on 2022 Tundra.

Reviewed in the United States on September 9, 2017

Verified Purchase

Product came quick and installed easily. Did have a little trouble with one area of the tailgate gap seal sticking to the factory sprayed bed liner but after using the included adhesive enhancer product it has stayed in place and does well holding out the dust. Some times when the gate is down for a while it doesn't fold down and has to be pushed down when closing the gate. Has held up well so far with things being drug across it and it being stepped on etc.

Didn’t stick well enough to keep out the dust

Reviewed in the United States on August 9, 2023

Verified Purchase

Purchased this and installed it before going up the Dempster Highway in Canada, I was hoping to keep out the dust. I cleaned my entire backend/tailgate with rubbing alcohol used the adhesion promoter and followed the directions to the T. I also used all of the extra length I had to further seal the sides, I thought I was ready for the gravel highway.
I sealed all the seams of my tonneau cover with duct tape to help prevent intrusion of dirt and hit the road. I was beyond disappointed when I got to my campground for the night and EVERYTHING was covered with dust in the backend, with heavier dust the closer you got to the tailgate. It had covered a nearly new microwave/convection over/air fryernthat I had next to the tailgate with dust. In fact the dust was so bad that it ruined that microwave (started smoking after it ran for a few minutes). A week later the seal started to peel from the tailgate, it’s still on there, but the opening now is even larger than it was before. I’m back from my trip and now need to figure out how to remove the seal. I’d like to find one what works better and won’t be buying this brand again.

I've had this on my truck for a couple of months and it is holding up perfectly. It was easy to put on, and the adhesion promoter stuff they give you really works! I haven't had any problems with the strips lifting away from the surfaces, and it's plenty sturdy material. I think it should hold up well for a good long time. Definitely helps keep wetness and dirt out of my truck bed when off roading!

Problems with the Rok Bloc

Reviewed in Canada on May 19, 2017

Verified Purchase

The Rok Bloc did not meet my expectations at all. I have a new Chev truck and the box profile is contoured with inch wide ridges separated by inch wide depressions. The tail gate has a flat profile. The instructions direct the installer to start a one end and stick down three inches of the strip at a time pressing it into the depressions and the ridges and sticking it down on the flat profiled tail gate at the same time. This results in a very wrinkled hinge becoming progressively worse as one proceeds. As a result the part adhered to the flat tailgate came loose within three days after application. Perhaps the instructions should have advised to stick it down starting at the middle and progressing to the ends leaving the part to be stuck to the tail gate until the box side was completed. This may have resulted in a better result. The manufacturer/retailer should advertise that the results for Chev/GMC owners will not be satisfactory as it is with Dodge, Ford or Toyota. I would not recommend this product to a Chev/GMC pick up truck owner.

Solved problem in my 2018 F-150 with dust seeping into box through crack between bottom of tailgate and box. Also sealed gap between sides of tailgate and box. It has held up through this harsh, cold winter. Especially great for keeping water out when going through high pressure touchless commercial car wash. Box has 3-fold hard BAK tonneau cover.
