Johnno Posted October 29, 2007 Share Posted October 29, 2007 Anyone used one of these bars that contains four dimmers? BR Google doesn't have any entries with that title. I'm thinking of getting a couple for a minimal installation in a school drama room where anything more complicated would be overkill (and overstressing on my budget). A second question. They have eyebolts built into them from which they can be flown: would using just two chains to do this constitute safe mounting (assuming four Par56s mounted on the bar, each with its own safety) or would you prefer to do more? (For ref: mounting height is about 3m above floor so if one chain failed the bar would swing down and could clobber a tall person). Oh.. answered my own question there since I am that tall person :) Link to comment Share on other sites More sharing options...
Pete Posted October 29, 2007 Share Posted October 29, 2007 Bearing in mind you answered your own question. What sort of chain were you intending to use?And what is the fixing the other end of said chain? Link to comment Share on other sites More sharing options...
Johnno Posted October 31, 2007 Author Share Posted October 31, 2007 I haven't made any decision over what I'll use but I think that hanging from the ceiling will be safer than mounted on a stand. Too many children milling round. And if it was on a stand the Governors would insist that it be safetied to the ceiling anyway. Do you recommend anything?

Johnno Posted November 1, 2007 Author Share Posted November 1, 2007 There are six 10ft x 4ft flats on our stage that are each held up only by two chains screwed to their top edge and hung onto one of the drape barrels. Four different gauges of chain in use from "substantial" to "bog". Probably done by the school caretakers. I'm currently in the process of replacing them with drapes (the flats not the caretakers...) so I'll use some of that chain. Edit: The other end of the chain will be attached by wall anchor into the concrete ceiling by our electricians. Link to comment Share on other sites More sharing options...
cliveybaby Posted November 13, 2007 Share Posted November 13, 2007 Hello I have 'had' to mount a few of these before I used a length of unistrut across the top of the barand fixed using all four of the m10 fixings thenstuded the unistrut to my anchors By doing this, you take the load off either end of the dimmer bar as the weightis even across its length Worked well but would never choose to fly these items Cliveybaby Link to comment Share on other sites More sharing options...
