Notes: The white plastic plug on the smaller tube is designed to reduce wobbling by filling the gap between the smaller and larger tubes. Please DONOT remove it. Lightweight & Durable: The stair climbing assist cane is crafted from lightweight yet ultra-strong carbon steel with anti-rust coating, supporting up to 300 lbs. It ensures long-lasting stability without compromising portability. Double Stability & Safe Grip: Ergonomic anti-slip foam handle reduces hand fatigue, while 4 non-slip rubber feet adapt to stairs of any material (wood, tile, stone). Dual-layer stability helps prevent slips, even on narrow or steep steps.
