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. ADJUSTABLE & SAFEEquipped with lock mechanisms, our sturdy telescoping ladder enables height adjustments in one-foot increments and secure locking with sliding latches. Textured steps and anti-slip feet ensure stability on various surfaces. PORTABLE & SPACE-SAVINGOur lightweight, retractable ladder features an integrated handle and Velcro strap for easy transport. When compactly folded, it fits behind cabinets or doors, under beds, and in car trunks, saving valuable space. VERSATIL
