A unique , heavy duty "C" section ladder with non-slip serrated round rungs with fully interlocking stiles for safety at extended heights. Although this design of ladder is not certified to BS 2037, it has been in constant production for more than 50 years, as its light weight and interlocking design makes for a lightweight ladder that can extend far beyond the reach of many much heavier models. Available as single sections, doubles, or  triples, this is the only design of ladder we know that can be easily converted to rope operation if required at a small cost. Can also be fitted with wall running wheels..... choose your requirements in the boxes above, the ladder price will automatically be updated.
