Description

Internal Seal Hatch Cover - Medium - 125mm

The Internal Seal Hatch Cover features a fully threaded lid with an integral watertight seal, providing secure and reliable access to storage compartments and buoyancy tanks. The seal is replaceable, helping to maintain long-term water resistance and performance.

For maximum watertightness, we recommend applying marine sealant around the body flange and fixing holes during installation.

This hatch is a direct replacement for RWO Marine 125mm Hatch Covers: R4050, R4052, R4053, and R4054.

Key Features:

  • 125mm screw-in inspection hatch
  • Integral replaceable watertight seal
  • Fully threaded lid for secure closure
  • Durable, easy-to-install design
  • Direct replacement for RWO R4050, R4052, R4053 & R4054
  • Ideal for storage compartments and buoyancy tanks

Optional Accessory:

  • Compatible with the A-BAG-KIT Hatch Cover Storage Bag for additional onboard storage.
