Abstract
A mesh cable tray comprises a series of longitudinal wires and a series of transverse wires connected to one another at nodes to form a grid, in which each transverse wire includes a base portion from which two parallel arms extend transversely relative to the base portion so that each transverse wire is generally U-shaped. The series of longitudinal wires comprises a pair of longitudinal edge wires which are disposed beside free ends of the parallel arms of the U-shaped transverse wires. The tray has protection members arranged in the regions of the nodes at which the longitudinal edge wires and the parallel arms of the U-shaped transverse wires intersect, in order to cover the free ends of the parallel arms.

- wherein each insert is produced by moulding of plastics material,
- wherein each insert includes a pair of half-shells connected in the region of a bending portion so that the insert can be fitted on at least one longitudinal edge wire as a result of deformation of the insert along a bending line of the bending portion and of mutual connection of the two half-shells.
A protection member for a cable tray which comprises a series of longitudinal wires and a series of transverse wires connected to one another at nodes to form a grid, in which each transverse wire includes a base portion from which two parallel arms extend transversely relative to the base portion so that each transverse wire is generally U-shaped, the series of longitudinal wires comprising a pair of longitudinal edge wires which are disposed beside free ends of the parallel arms of the U-shaped transverse wires,
