RV Escape Hatch and Lid classacustoms

What brand of escape hatch do you currently have?
Class A Customs carries Heng's Brand Escape Hatches

The current design of Heng's brand escape hatches will not match older style Heng's escape hatches.

Heng's purchased the Jensen/Elixir brand name some years ago.

The following part numbers and design of the escape hatches are the only Heng's style we carry.


Ventline no longer makes escape hatches, the sizes and hinge assembly are not the same as Heng's, Elixir or Jensen brand, you can not put a Heng's lid on a Ventline escape hatch.




How are Escape Hatches Measured?
The name of the Heng's escape hatches are shortened names to easily identify the escape hatch, it is not the cut-out measurement or the flange measurement.

You will need to verify your cut-out dimension to accurately find the escape hatch you are needing.
