Jumbo J1002500 Platform without hatch 60cm x 250cm A platform without hatch is usually installed on each landing of a scaffolding, which is wide enough to take one platform with hatch, and another without hatch, next to each other. These scaffolds are normally 135 cm wide. Since the user of the scaffold climbs from one level to the other, on the inside,  he goes through the platform which has a hatch, and closes it, soon after getting through. The side platform ref J1002500 has no hatch, and is therefore safer to stand on.
