Mounting lights on trunking

Baldyhugh
Hi


A customer of mine has asked me to fit some lights on an existing job that I am currently in the middle of. I have a 3x3 galv trunking suspended at high level and was considering mounting a few 5 foot led vapourproof fittings directly to the underside of the trunking. It would be the simplest way that I can see but have never done it like this before and was wondering if it was an acceptable method. 


thanks

    When ever I fit a fitting like this up on trunking - I'd always use a round lock nut onto the dia 20mm bush to secure the bush to the trunking and then install another lock nut in the fitting; the first lock nut gives it a little spacer between the fitting and the trunking. Less fitting plastic cracking etc that way. 


    As others have said - there are plenty of other ways to do the job, but certainly you can hang lights from trunking. 


    A 4mm brass screw and nut (the screw- as used for a metal conduit box lid) through the trunking bottom with the head of the screw in the trunking, would secure the flimsy clippy thingy that the fitting can hang off of.

    I don't like the flimsy clippy thingy though to hang fittings from but it does provide a fast install method on brick walls or concrete ceilings. 

    The hooks would allow you to suspend the fittings lower down........if necessary. Id use jack chain though between the hook and the fitting. 

    This picture was taken from the internet to give you the idea - you can get a whole flat plate with a hook on it that'll fit onto the conduit box.
