Earthed frames for your safety.
Steel house frames must be permanently earthed in accordance with the requirements of the local electricity authorities.
Installation of wiring for electrical services is made quick and easy by the provision of pre-punched service holes which can be plain or flared.
Plain holes, which can be either pre-punched, hand punched or cut out with a hole saw, require grommets to be fitted before wiring is pulled through.
Brackets and service fittings are screwed to the frame with self-drilling screws.
