Features Details Superior Load Capacity: VEVOR telescopic ladder is made of thickened aerospace-grade aluminum alloy, with a maximum load capacity of up to 400lbs. The interface components are also designed with aluminum alloy to withstand freezing weather. The product has been certified by ANSI and EN131 systems, ensuring your peace of mind during use. Anti-wobble Anti-slip: To enhance safety, we have widened the steps to 3'' / 75 mm and extended the aluminum tubes at the step junction to 3'' / 17 cm. Together with the top anti-slip sleeve and bottom anti-slip foot design, the ladder has reduced wobbling during climbing and standing, providing protection for both walls and floors. Convenient Storage: The foldable telescopic ladder is lightweight and compact, making it easy for female users to carry. You can place it almost anywhere, including under the sofa, behind doors, or in the car trunk. It is more portable and space-saving than traditional ladders. Independent Locking: The ladder can be adjusted in length through the independent locking keys on each step. The independent locking design ensures better safety during frequent climbing operations. When retracting the ladder, simply use both thumbs to release the lock buttons for a smooth and stable descent, avoiding any risk of pinching your fingers, making the operation safe and simple. Professional Climbing Assistant: With an extended height of 15ft, the ladder is suitable for professionals and home users who require frequent use of ladders. It can be used for house renovation, equipment installation, construction site aerial work, home repairs and decorations, painting, and more.
