The RIK itself has highly malleable perforated aluminium wings which can be shaped to fit into most spaces and do not need to be centred between the joists. All RIKs come with a clip so that any bare wires can be neatly held in place making later installation and adjustments easier. Roughing-in-kits (RIKs) are rough guides for custom installers which are designed to fit into standard ceilings between joists and attach to plasterboard. Mordaunt-Short?s Avant Architect RIKs are made to industry standards and are used in the installation process before much of the electrics have been fitted.
