More InformationOptions
Reliable Latch Engagement
The Lewmar Low & Medium Profile Hatch Catch Block is a genuine OEM replacement designed to restore your hatch. As a key component in the catch mechanism, it ensures that the hatch closes securely and locks into place with proper alignment.
Smooth, Reliable Hatch Operation
With a new catch block installed, the hatch engages cleanly and holds fast, preventing partial closure, rattling, or unexpected opening while underway. This restores the smooth, confident operation expected from Lewmar’s premium hatch systems.
Durable, Marine-Grade Construction
Manufactured from corrosion-resistant materials engineered for saltwater, UV exposure, and constant mechanical load, the catch block delivers long-lasting performance even on vessels used frequently or in harsh conditions.
Improves Seal Compression & Weather Protection
A properly functioning catch block helps maintain correct compression on the hatch seal, reducing the risk of leaks, drafts, and water ingress. This not only protects your interior but also prolongs the life of the hatch gasket.
Exact Fit for Low & Medium Profile Hatch Models
Designed specifically for Lewmar’s Low Profile and Medium Profile hatch ranges, the catch block is a direct-fit replacement that installs easily with existing hardware locations, ideal for maintenance, repair, or full hatch refurbishment projects.
