Werner 57711320 3.57M Square Rung Double Extension Ladder

The Werner 57711320 3.57M Square Rung Double Extension Ladder is constructed using high-grade aluminium and extends to 6.09m for a safe working height of 6.64m*. Box section stiles provide added rigidity and sturdiness and ensure maximum performance for use on building sites and high-rise buildings. Its smooth-glide runners help to adjust the ladder height easily. The unique wrap-around top clips and locking catches can securely latch onto any rung to lock the sections, with a wide stabiliser to reduce wear and tear from instability. The square-shaped rungs and plastic feet are slip-resistant for added safety during use.
