Rated 5 out of 5 by 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! 21 Apr 2016
Rated 3 out of 5 by 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. 31 May 2015
Rated 4 out of 5 by Surface box 20mm knock out Used these to mount thermostats with cable glands in the knock out holes. I pushed the knockouts from the outside and they broke away cleanly. It requires a fair bit of force. Good price and fine for what I needed. 11 Dec 2014
Rated 5 out of 5 by Inexpensive and simple For those having issues reliably removing the cut-out, this approach works for me every time... Drill a central hole about the same diameter of your screwdriver, insert screwdriver, and lever to one side. The cutout should then come straight out cleanly. 3 Dec 2014
