An extension ladder is a non-self-supporting portable ladder with adjustable length. It consists of two or more sections that can climb more than 23 feet, reach high windows and get onto the roof, which is why it must require heavy duty and durability. Choose thicker tubing and stronger connections to ensure user safety. Inquiry from Extension Ladders manufacturer directly
