Extender Box & 3-D Cover

New Product Bulletin – Extender Box* & 3-D Cover*

With our new Extender Box and Three Dimensional Junction Box Cover, wiring connections have never been easier. Both items can be unsnapped from the fixed junction box, enabling penetrating wires to be withdrawn below the ceiling, offering unrestricted connection access and other features.

Extender Box, 1232E: Double the volume of our popular 1232 or 1247 series junction boxes by snapping on our new Extender Box.

Why stop there? Each Extender Box contains the same number of knockouts (7) as the fixed box. Being stackable, adding two (or even more) extender boxes provides further space & wire access holes for the most complex connections. Like our original junction boxes, the Extender Box accepts our 1242 series covers.

Instead of stocking dedicated larger boxes, our new Extender Box allows the fixed junction box to grow as needed.

3-D Junction Box Cover, 1242-XXB: Our new 3-D Cover offers a triple treat; unrestricted wiring access, increased volume, and greater ballast accommodation.

Wiring access: With two 9/16”, and two notched 11/16” thermal knockout holes on the 1″ tall side faces, power and other feeds can be brought into the removable cover. Like the Extender Box, this enables its withdrawal, limited only by wire feed lengths for unfettered below ceiling access, whether for connection or ballast change.

1242-18B shown. Other hole configurations available.

Increased volume: Adding our 3-D cover to either the 1232 or 1247 series junction boxes increases their volume by about 50%. Combined with the Extender Box, the volume of the fixed junction box may be increased by 50%, 100%, 150%, etc.

Greater ballast accommodation: Since the face of 3-D cover clears the retention spring, larger ballasts may be affixed. In fact, sizeable ballasts can extend beyond all edges of this cover.


Both items are made in progressive dies for the most competitive pricing.
