This is an aluminum scissor-style attic ladder that pulls down from the ceiling. It fits a rough opening of 30 x 30 in (75 x 75 cm) and has 12 steps. It reaches a maximum vertical height of 9.8 ft and supports a load of 1100 lbs.
The ladder has a high-temperature sprayed finish that is hard, wear-resistant and corrosion-resistant. An anti-slip device sits at the bottom, and a retractable pull rod makes it easier to operate. It is made by a mechanical forging process from a solid titanium-magnesium alloy.
The material has an ultimate tensile strength of 106 MPa and a tensile yield strength of 46 MPa. Elongation is 22.0%. In an impact test, a 16-pound sledgehammer deformed it only 30 degrees without breaking it.
