摘要：A support (of metal or moulded plastics) for an elongate body (e.g. a pipe)passing through a hole in a wall, comprises an apertured plate (10) fixable to the wall andformed with a sleeve (18) surrounding the aperture and extending into the hole, the pipepassing through the aperture and sleeve and being held spaced from the inner surface ofthe hole by means (integrally formed lands (14) or a ring, or a ring fittable in thesupport). Supports are described having two or more apertures (12) with respectivesleeves and bearing means, with areas readily broken away to allow formation of furtherapertures, which are of separable parts allowing fitment to an existing pipe run. Platesare said to be provided with volumes of intumescent material operable to seal the holeagainst fire, this material acting as the bearing means, or being a layer covering the faceof the plate on the wall or as volume between said sleeves(s) and further sleeve(s)formed therearound. Arrangements are described for supporting elongate bodies (e.g.pipes, cables, cable trays...) passing through solid and cavity walls making use of thedescribed supports as well as outer piping-, and intumescent material-sleeves extendingbetween supports at opposite ends of a hole in a wall; as are methods of using thesupports and other noted elements.
