Abstract: A single run or extension ladder particularly suitable for use where electrical safety is significant. Stiles 6 are each formed from a pair of elongate hollow members 5 fabricated from glass-fibre material. Rung supports 7 are formed from an aluminium extrusion comprising a pair of piped edge sections 8 separated by a pair of webs 9 in the nature of a box-section 10. The elongate members 5 extend through and are attached to the edge sections 8 by an adhesive. The rung supports 7 thus space the elongate members 5 adjacently apart to form a stile 6. The ends of rungs 12 are mounted in laterally aligning apertures 14 in the webs 9, the end of a rung 12 being crimped back onto an outer of the webs 9. End caps or feet 16 are provided on the stiles 6. An extension ladder is formed in conventional manner, to that end, saddles 18 telescopically captivate a pair of such single run ladders together.

Abstract: A ladder is provided with an attaching device at its top end whereby it can be quickly and securely attached to a vertical pole, tree-trunk or the like. The attaching device comprises a pair of jaws to pass one on each side of the vertical pole, and it can pivot until the jaws engage the pole. The ladder is suspended from the pivot of the attaching device, and may then be secured at its bottom end to prevent it from swinging.
