The four main parts of the fixture set comprise two angled guide and holder fixtures (5) for attachment to the wider ladder (1) side rails (2) and two grip claw fixtures for attachment to the narrower ladder (7) side rails (8). All the fixtures have like-shaped fastening parts which fall in a plane separate from the fixture other parts. Each fixture part has a number of position determining pins for working in conjunction with corresponding holes in the side rail plain surface. At least one nut working inconjunction with a screw (4) connects the fixture part to the side rails. |
