Just stocked up on 20 sets of Companionway Screech preventers. I want to bring you up to date on this product. Up until now I believed these worked on both the Mk I and Mk II. They do not work on the MkII!! I thought the hatch was changed partly through production but apparently not. All Mk ll have a different sliding hatch that is similar to much later Catalina models.
