Spreader Bracket Retrofit C-25, C-27

Part #: Z1903
Replace your original Catalina 25 and Catalina 27 aluminum spreader castings with stainless steel weldments. If you are replacing your brackets on a Catalina 27, read note (1) below.

The original cast aluminum spreader brackets will, on occasion, fail catastrophically. This can lead to the loss of the entire rig. There is typically no warning that failure is eminent. They don't bend or crack then break. They just break.
These stainless steel weldments eliminate the problem. The lower shroud tangs are fitted to the same location as your old ones so your existing lower shrouds can be used.
• Spreader brackets with lower tangs
• Fasteners
• Large compression tube
• Small compression tube
• Lower shroud clevis pins
• Cotter pins
• MareLube anticorrosion gel
• Delrin dielectric self adhesive insulator to prevent corrosion at the stainless/aluminum interface
• Latex gloves
• Cotter pins for spreaders
• Two lengths of seizing wire to re-secure the upper shrouds to the spreader tips
• Installation drawing
• Installation instructions

It is easy to tell if your boat still has the old cast aluminum spreader brackets as they are the same dull gray color as the castings at both ends of your boom. The new stainless fittings are shiny, chrome like stainless steel.
1) Will not fit Catalina 27's with hull numbers in the following ranges: 1421-1450, 2465-2549, 3101-3150, 3950-3999, 4701-4725, 5042-5051, and 5140-5149. These boats were not built in California and used a different mast. There may be other ranges as well that we have not discovered yet.

2) We recommend installing new spreader boots at the same time to prevent tearing the mainsail and the leech of your headsail.
