AT Extender Box – Junction Box Extender for Airtight I.C. Boxes
Since 2007, we offer our Extender box (1232E) to double the internal volume of our 1232 series non-airtight junction boxes. We have recently modified the junction box used on our Airtight I.C. Boxes, to similarly allow multiples to be secured together, offering the same volume increase feature.
To use these Extenders, like always, two #8-32 self-tapping screws are installed into the cover mounting holes (but only partially and without any cover in place).
A second identical J-Box = our AT Extender Box, item # 1281-92-1 (or 1481-92-1 for our new line of Airtight IC Boxes with Junction Box 70), is then joined by rotating it so the (new) angled slots on the rear face engage under the heads of the partially installed screws. These screws may then be fully tightened, securing the AT Extender Box to the base J-Box.
