摘要:
A cable tray 1 including a formation 7 for engagement with a separate cable support 4,6,7,8 to enable the cable support to be mounted thereon. The formation may be an aperture and may engage with the cable tray with a snap fit. The cable tray may include a number of spaced apart rows of spaced apart formations. The cable support may include two arms 21 for receiving cable therebetween. The cable tray may include a cover 25 and clips for retaining the cover. The clips may be lockable. The cable tray may be moulded in one piece.
摘要:
A stackable moulded junction box section, suitable for construction of underground junction boxes. The section includes integrally moulded support means (55,56,57). The support means can comprise a step (52) and can also comprise a receiving means (56,57) for receiving and supporting a support (58), which may be moulded integrally with the section and then separated for use. The section may comprise inner (50) and outer (51) walls joined by cross-reinforcement portions (52) which divide the space between the walls into cavities (53). Provision to form apertures between the cavities, which may comprise a knock out portion (54), can be provided. The apertures may be open to the bottom of the section, so that the section may be placed over a conduit. The section may include projections to enable it to be stacked on end. In another embodiment the section is formed from two or more separate interlocking components.

摘要:
A retro-reflective assembly comprising a substrate (10, 30) and a binder layer (12, 32) coated onto the substrate. Glass beads (14, 34) which are partially metallised (16, 36) are at least partially embedded in the binder layer. The assembly can be joined to another structure, e.g. a cover (38) or a support (20) by high frequency welding at a location where partially metallised beads are present.

A marker post which can be quickly installed at the edge of a road comprising a flexible body (10) of part circular cross-section with an elongated metal base (12) preferably of T-shaped cross-section. To secure the post in place the body is flexed away from the base so that the base can be driven into the ground with a hammer. When the body is released it returns to an upright disposition.
