Insulated to 25,000 Volts, these Fibreglass Extension Ladders are the top choice for Electricians and those needing ladders for spark risk environments. Manufactured from distinctive yellow GRP fibreglass stiles to EN131 European standards, the ladders are fitted with aluminium rungs for additional lightweight. Dual action swivel feet grip the floor securely on the one side with a heavy-duty rubber foot or flip over to reveal a spike that securely anchors the ladder in the ground. This GRP fibreglass ladder is fitted with an automatic clutch, wall-running wheels, and interlocking clip that prevent sections from coming apart during use and for ease of carrying and transportation. The rope operated mechanism helps extend the ladder to its highest position easily and quickly and with less effort needed than pushing the sections up manually. At the ladder top a pole bow enables easy tie off to telegraph poles, etc.
