REDUCED WOBBLEAfter extensive testing, we've added two new triangular stabilizers to the extendable ladder, which effectively reduce the shaking amplitude from 30° to 10°, and enhance the ladder's stability by 36% compared to similar products. LARGE DIAMETERCrafted with a larger diameter of high-quality aluminum alloy tube, our ladder resists deformation when extended. With nylon fiber-reinforced plastic parts, it ensures unmatched durability & stability, supporting up to 330 pounds.
