About this product
SpecSeal EP Powershield Electrical Box Inserts install within steel electrical boxes directly against the back of the box. Powershield Box inserts are equally suited for remediation as well as preinstallation before the boxes have made it to the job site. Powershield Box inserts incorporate pre-scored openings allowing for easy installation around ground lugs.
