Installation Notes
Confirm that the ceiling height falls within the ladder's adjustable range.
Verify Rough Opening: Frame the ceiling opening strictly to the nominal product dimensions specified in the installation manual.
Confirm Ceiling Height Range: Ensure ceiling height matches the model configuration (standard range up to 10' 11" or high-ceiling models up to 11’ 10").
Position & Fasten Frame: Raise the pre-assembled frame into the rough opening, level with shims, and secure through the perimeter box sides.
Check Unfolding Clearance: Ensure adequate floor space and swing clearance arc before lowering the metal ladder sections for the first time.
Adjust Base Footing: Position the protective plastic feet flush against the floor to ensure weight is evenly distributed across the metal structure.
