The block itself was fine. It feels sturdy and wide enough to fit on my bike's front wheel. My complaint is that the hardware used to attach this gasket to the trailer is not long enough to fit through the pressure treated wood on the trailer floor. The hardware is at least an inch shorter to fit through a 2" x 8" board. All of the screws need to be at least 1 inch longer to work and they were useless for what I have. I had to go to the hardware store to get what I needed for the job. Otherwise I would have given the product 5 stars.
