suspending galvanised conduit

[studentspark]

Whats the best way to suspend conduit from a ceiling. Its for lighting

the drop will be about 500mm

What are you going to suspend it from? Steel girders, concrete, wooden joists, plaster board.

If you are fefering to making a drop of 20mm conduit to an industrial type lamp (ie a Mazdalux enamelled shade fitting - very retro) then you would use a special eyeball dome cover, it fits over a BESA box and has a movable eyeball front for the drop conduit- idea being if someone knocks the lamp it swings gently rather than breaking.

If you mean simply fixing a conduit / boxes to a ceiling to support a light, ie a florry on chains then simply use standard fixing methods preferably into the joists behind above the light point (or a noggin fixed for the purpose) or if thats not an option use the worm fixings into the plasterboard - they can hold huge weights for their size, but err on the side of caution and use more fixings than if you were fixing to a more robust material, ideally the BESA box supporting the light drop will be secured to wood or metal.

Finally if you are fixing to a raw girder ceilling then Britclips make a mind numbing array of spring steel clips to fix conduits to all and sundry

Glad to see someone doing it properly in galv!!

Think we need a better idea of what you want to fit to what kind of surface...

Many thanks

Not really sure about the ceiling but the office has a couple of floors. The floor above the ceiling has a concrete type feel and look but are not solid they feel quite hollow when you knock them

The enammelled shade fitting hanging on a chain was the look I was after.

I was not wanting to drop the actual conduit to the shade.
The conduit would be ran horizontal the ceiling, but needs to be dropped to clear boxed in beams. then from the couduit hang the lamps

I was thinking of this to hang the fittings

Yep thats the right fitting, use it over a BESA box with single jack galv chain. You can buy silk covered twisted 3 core flex to complete the retro look. Your whoesalers may well have the conduit and fittings in black enamel which would be more in keeping with the 1930s theme.

Like the shade, try reclamation yards too, they often have originals of these, Mazda made them in a lovely pastel blue with a clip over wire guard or slightly dished glass, tradenamed Mazdalux
