Fitted one yesterday and found it awkward to use, the mechanism is just too tight compared with other brands making it difficult to use, this in addition to the very tight Eclipse bathroom thumburns also bought from Toolstation made the bolt very difficult to operate. I had a 220 mile round trip to fit these as a safety measure and wish I have checked both bolt and thumbturn first as I had travelled too far to consider sending them back. Do not recommend using either this bolt or Elipse thumbturns
