These CNC machined and formed channels are the foundation we use to build our custom flush mount hatch assemblies. The geometry is such to allow the lid of equal thickness to sit flush with the top flange surface when compressing a 1/4″ gasket at 50 percent.

Material: 0.125″ or 0.188″ 5052-H32 aluminum, domestic

Dimensions: see drawing

Customization Requests: send a quote request indicating volume and dimensions of your custom hatch channel.

Disclaimer: building high quality custom hatches is an advanced skill that we have perfected over the years and there is a reason complete hatch assemblies are not cheap. For the DIYers, please understand that our technical advise on how to build your own hatches will be limited. No returns will be accepted on this product.
