1″ Service Box Extension with 1 Set Screw
$6.90 – $14.23
Our service box extensions are made from Schedule 40 pipe and are used to increase the height of an existing service box or to accommodate greater depth in a new installation. The service box extension is installed by removing the existing cover and sliding the extension over the top of the box pipe. The extension is adjusted to the desired height and the set screw(s) are tightened to lock it in place before replacing the cover. Extensions are made in lengths from 3″ to 24″.
