Hatch Adjuster for Bomar 12-3/8" x 12-3/8" Hatch

Part #: Z3929
This riser arm (also referred to as a hatch adjuster) is used on the aluminum framed main cabin hatch found on some models of the Catalina 27, Catalina 28, Catalina 30, Catalina 320, and Catalina 34. The complete hatch is our part number Z1827. This part is for hatches that were made prior to 2005. Check the additional photos below carefully to ensure that this is the correct part.
The stainless tube is 3/8" diameter X 8" long. Not all hatches use this length tube. Measure your hatch to be sure.

Some larger Catalinas used a similar hatch built by Lewmar but the riser arms are different than the one pictured here.
The Bomar hatch that this adjuster fits has the following dimensions:
• Deck Flange Overall: 12-3/8" x 12-3/8"
• Cutout (the opening in the deck): 10-3/4" x 10-3/4"
• Hatch Opening: 9-5/8" x 9-5/8"

When you order a special order item it sets off a chain of events like Willie Wonka in the chocolate factory. Once you turn the valve the chocolate is coming down the pipe. If you then decide you want caramel, the chocolate is still going to come out of the pipe. We can't put the Chocolate back in the pipe, so someone is going to have to eat it, and it's not going to be us! Your order can't be canceled, returned, or magically changed into caramel, so please order carefully the first time!
