Roof Hatches

Just like with access panels, we trust the Williams Brothers Corporation of America to provide a stellar product to our customers when it comes to roof hatches.

The Williams Brother Roof Hatch offers features such as a heavy duty lock and handle assembly and heavy gauge, weather-resistant gaskets and fully concealed hinge hardware. Since the hardware is located on the interior, it renders rust unlikely. Pre-lubricated compression springs, encased in zinc-plated telescopic tubes, are held in place by 3-sided welded brackets. A durable and re-coatable gray primer finish comes standard.
