The XMS ECO Line 3M Telescopic Ladder, made by Telesteps, comes with a triangular tube design, this increases strength and makes the ladder more resistant to twisting, a fine XMS buy at a great price. Big and small, these Telesteps ladder's are both simple and user friendly to use, with no compromise in quality or safety. Lightweight but strong, made of high quality anodised aluminium with glass fibre reinforced plastic fittings and is also, crucially, EN 131 and SP (RISE) certified. The Eco Line has its elegant air-damping system built in to minimise squeezing fingers, and a simple locking system with only two buttons. The ladder is designed to be used at a 75 degree leaning angle, while angled feet ensure you always have maximum surface contact. A rubber top section also helps .
