• Access method: Determine whether the hatch will provide access from a fixed ladder or stair system to ensure the selected size offers safe and convenient rooftop entry.
• Insulation requirements: Review the project's thermal performance requirements to determine whether the standard insulated hatch or the optional FESCO insulation configuration is appropriate.
• Security requirements: Consider whether the standard interior and exterior handles with padlock provisions satisfy the building's rooftop security needs.
• Hinge orientation: For hatches with a width or height greater than 48 inches, the hinge is positioned along the longer side to support proper operation.
