Rated 4 out of 5 by Ideal trunking to conduit box Great box for connecting 20mm plastic conduit to plastic trunking. Only gave 4* on performance because the knockout didn't work for the 20 mm hole and had to be drilled. I box was badly broken because of this so beware. 26 Dec 2012
Rated 2 out of 5 by Limited functionality This surface box only has ONE circular knockout on one of its sides (there is another one on its back/base). This greatly limits its functionality, and to be honest it is the first time I have come across a surface box designed for conduit that only has ONE knockout for circular conduit entry on its side. This box can therefore only be used if your wiring is terminating at this box. 10 May 2012
