"I needed this to fit to an older MK consumer unit (16th Ed), they fitted perfectly. They are reasonably priced (cheaper than wylex). Pity the photo is showing it on its side, as this confused me a little as to how it would fit on the din-rail. Just had to turn my head a little to look at it!"
"I hate using mcb's to fill in unused gaps on consumer units, these blank plates are easy to fit and they mean that we can keep the mcb from the un used ways, simple and cost effective, every ones a winner with these."
