Our surface mount floor hatch is our most economical floor hatch for interior use with light pedestrian loads. It has an interior angle mounting flange and features an exterior lockable hasp. The load rating on our surface mounted floor hatches is 150 psf and they are only available in a aluminum construction with single door configuration. These are best for the same locations as our angle frame floor hatches only more suitable for locations that don't have regular foot traffic as they do mount above the opening as opposed to bolting into the opening.
