Double hinged frames are permanently connected and braced by a rigid bar that provides a unit of exceptional stability. This rigid bar also offers the possibility of attaching additional rope ladders, climbing ropes etc. The standard units are 2.74 m (9’) wide and 3.05 m (10’) high, but ‘bespoke’ sizes are easily accommodated to suit individual sites and user requirements. These timber units can be fitted with traditional oval timber bars, or brightly painted ‘colour-coded’ steel bars. To ensure safety and stability, each frame is wire-braced and also fitted with a rigid connecting link, as appropriate.
