Questions & Answers

I am being told that EFB610BTBK EVOLUTION FLR BOX FLUSH CVR WITH SOLID TOP BLACK has been discontinued and there is no replacement, is this the case?

Asked by: Rick
Hello Rick, EFB610BTBK is obsolete and has been replaced with EFB6810BTBK. The covers are exactly the same except for the replacement cover having a different gasket on the bottom of the cover. A link to the product page for the replacement cover is shown below. https://www.legrand.us/wire-and-cable-management/floor-boxes/concrete-floor-boxes/evolution-series-efb6-efb8-efb10-floor-box-flush-style-cover-with-solid-lid/p/efb6810btbk?text=efb6810btbk Thank you!
