Rated 4 out of 5 by from Easy to knock and drill out 20mm knock out knocks out easily and cleanly. Sides are uncluttered and can be easily drilled out. Enough clear space to allow 20mm and 25mm back nut to seat cleanly.

Rated 5 out of 5 by from It does the job An inexpensive product that does the job! What can I say about a simple back box? Knockouts can be tricky but take care and it should be OK!

Rated 3 out of 5 by from Knock-outs can be tricky Does the job, but some of the ones I used had knock-outs that refused to budge without cutting. The back can crack if you try to knock out without cutting.
