      Comments about Spring Loaded Blocks on Slides:

      Over the years, Scaeffer has always been my favorite when it comes to workmanship of each part I've purchased. I also find Schaeffer to be the most reliable of the sailing parts providers when it comes to performance. I will continue to use them when ever possible.

          I would buy this product again and expect I will because after 10 years of moderate use the original wore out.

                great upgrade for my 30 year old Tanzer. Only wish they a screw type stop was still made for older simple boats

                  Comments about Spring Loaded Blocks on Slides:

                  The cars are very well made, thus it is surprising that the little button you have to pull up to adjust the car have quite a sharp edge to it. It would be better, if they were rounded of a little more.
