Top tubes are either a round tube 4″ (100mm) diameter with flat ends and either 9′, 10′ or 12′ length for the Cave Southampton climbing frames or a square tube 3″ (75mm) square with flat ends and 10′ length with rings fitted at the rope attachment points (the ropes are fixed with a D shackle) for Niels Larsen climbing frames.
All rope attachments have a 4″ diameter spliced eye at the top end (Cave frames) or a D shackle (Niels Larsen).
