Hi, I wonder if anyone can help due to their own experience. I want to set up a Fireman's Pole between 2 levels in my garden. These can easily be ordered ftom playground equipment suppliers but they're all too small. I need the horizontal bit at the top (to be bolted to a wall) to be 4ft long then the vertical bit (I've accounted for 2 to 3ft to be concreted in) to be 18ft long. Mr Google was uncharacteristically unhelpful. Anyone know of a company that does bespoke work like this?
