Review on Cal Hawk AZGA125 Grommet Assortment Electrical: Complete your Electrical Projects with Versatile Grommets! by Young Toulson

I am using grommets for piping through the inside/outside wall of my double width trailer. The installation is intended for a security system, namely for hanging Nightowl cameras on two corners of the trailer body. Installation is best done through the attic vents and through the "skin" of the trailer. The grommets provide excellent passage through the trailer skin to protect the cord from future short circuits.
