The Cosco All-In-One-Ladder utilizes two types of locking systems. The

system to be reconfigured into five ladder types: ➊ Step, ➋ Stairway,
➌ Wall, ➍ Scaffold and ➎ Extension ladder configurations.
Four Rail Lock Pins on the Outer Ladder Units of the ladder permit the
telescoping sections to be adjusted in length. This rail lock pin assembly
fits in any Rail Lock Port of the Inner Ladder Unit, allowing foot by foot
adjustment on either end of the ladder.
