Zefyr's roof hatches are designed for the purpose of allowing personnel access to roof areas on buildings without risk to workers or people in the surrounding area. This is ensured with the simultaneous raising of protection barriers with the opening of the hatch.
1. Curb (sit on)
Raised from the surface of the roof - pedestrian loading
2. Curb (drop in)
Dropped from the surface of the roof - pedestrian loading
There is no limit to the size of the opening that the units can fit onto, however, the bigger units (limited by the weight an individual can lift and the sizes of sheet metal available) will need multiple lids and sometimes, with the access of heavy machinery, the cross members have to be removable.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Zefyr Group is consulted before specifying.
