I bought some acoustic plasterboard, its quite heavy (around 23kg per sheet). The instructions said to use 65mm metal nail ins. I ordered these from a seller on ebay and they sent me the wrong thing, they sent me metal ceiling anchors. My question is, will they do the same thing and achieve the same result? Or are the nail in's stronger etc?
The reason im asking is because the house is due to get plastered on monday so I need to get these boards up tomorrow!
I can't find any in stock in any hardware store or builders merchants.
This is a picture of the ceiling anchor they wrongly sent me:http://i68.tinypic.com/2z3s840.jpghttp://i68.tinypic.com/2z3s840.jpg
This is the metal nail in that the manufacturer of the soundboard recommends:http://i63.tinypic.com/v67nyt.jpghttp://i67.tinypic.com/rkat8l.jpg
Any input would be much appreciated.
