Product Information

Replacing your hatch acrylic is easy - simply remove the lid, unscrew the frame and pull apart, the old acrylic will drop out and you can reassemble with your new acrylic.

Please note that depending on the age and condition of your hatch, it is not uncommon for the Joining Inserts to break as the frame pulls apart. We recommend having a replacement to hand so you do not get caught out halfway through the job. We will happily refund any unused Joiners.

Lewmar Hatch Identification

Distinguishing between Lewmar Low profile and Medium profile hatches

These two variants look alike but have differing hatch frame thicknesses.

  • Low profile hatch lids are 22mm thick
  • Medium profile hatch lids are 27mm thick

Distinguishing between Mk 1 and Mk 2 hatches

The design of Lewmar Low and Medium profile hatches changed from Mk1 to Mk2 between July and December 2000, so if you are certain your hatch was constructed before or after this time then you should know which design you have.

If you are uncertain or require confirmation, then there are a few ways to check.

  • Roll pin.  Mk 1 hatches (left) have a visible roll pin (marked in the red circle), on the underside of the lid near the hinge, Mk 2 hatches (right) do not.

  • Lens code.  All Low and Medium profile hatches have a lens code, which is embossed on the underside of the lid next to the handle. You will have to pull the seal back to reveal the lens code.
