Questions & Answers
How do I know if it is compatible?
This hatch has a 133mm clear opening and needs a 145mm mounting hole. If you are replacing an existing hatch, check that the cut-out matches.
How should I fit it?
Bed the ring on a good marine sealant and fix it with suitable stainless screws so the joint to the deck or bulkhead stays watertight.
Note: Installation with a quality marine sealant is recommended to keep the deck or bulkhead watertight.
