The clever design of the Werner Telescopic Combination Ladder allows you to use it in four different positions. It turns into a stepladder, odd legged stair ladder, extension ladder or a scaffold plank support. The hinged centre joint and telescopic legs let you fold the ladder for easy transport. All the joints lock securely with a simple Click-Lock system. The all aluminium riveted construction makes for a lightweight and super strong ladder. Maximum load 115kg.
