Abstract: A method of installing a telescopic shelf in a cabinet comprises installing a pair of facing guides, each guide having first and second brackets fixed at opposed ends of the guide and each bracket having either a planar lug or a hook for engaging with a series of mounting holes. When the guides have been installed, a telescopic shelf can be slid into the facing channels. As the brackets are fixed to the guide and, the fixing of the guides within the cabinet is carried out purely by engagement of parts of the brackets with the mounting post, there is never any need for loose pieces to be used within the cabinet. The brackets are telescopically adjustable to accommodate guides and shelves of different dimensions.
