摘要:
An article, particularly a cable tray 1, for installation on a flat roof 12 of a building. The article has an underside 10 and a side wall 11 extending upwards from the underside. A first part of a piece of fabric 9 extends over at least a part of the underside of the article and a second part of the piece of fabric extends over at least part of the side wall of the article. The fabric acts as a cushion reducing the risk of damage to a surface on which an article is installed. The fabric also acts as a wick operative to draw moisture away from between an article and a surface on which it is installed. The fabric may comprise hydrophilic material, such as polyester, and may be non-woven. The article may be moulded and the fabric incorporated into the article during moulding.

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 device comprises a white retro-reflective portion and at least one further retro-reflective portion displaying a blue or red colour. The white retro-reflective portion has a performance of less than 180 cd/lux/m² and the coloured portion has a performance of at least 10 cd/lux/m² when blue and of at least 15 cd/lux/m² when red. Such performance is measured in accordance with the requirements of British Standard 873 parts 6 and/or 8 (1983) at an entrance angle of -5 o and an observation angle of 20'.
