1) This collar only fits the Catalina 36 with in-mast furling built during 1999 and later. Before that date the furling mast was not a normal factory option. However there may have been a few boats built by special request with a different rig. If you have a boat built before 1999 with a furling mast, call our tech support at 916/843-1971 for assistance.

2) For a collar to fit a Catalina 34 or Catalina 36 equipped with a standard (not in-mast furling) mast, see the related product below listed under "May we also suggest"

3) The price includes only the mast collar casting. No hardware is included.

4) We have found that the quality of the castings supplied for these parts varies greatly and only offer them as a convenience for our customers who want the original equipment part.
