Arlington Industries 664 Cast Aluminum Sill Plate with Screws and Compound

Arlington Industries Cast Aluminum Sill Plate with Screws and Compound

The Arlington Industries Sill Plate is a cast aluminum sill plate engineered to seal and protect electrical service entrance conductors at the point where they pass through a building's sill. Built from durable cast aluminum, this sill plate is designed to withstand the outdoor exposure typical of a service entrance location while providing a stable, weathertight mounting surface. This sill plate ships complete with mounting screws and sealing compound, giving electrical contractors everything required for a proper installation without sourcing additional hardware. Whether used on new construction or as a replacement during a service upgrade, this sill plate helps close off the sill penetration cleanly and securely. Sill plates like this one are typically installed at the point where service entrance risers, conduit, or cable enter a structure through the sill, and are commonly used alongside the utility company's meter equipment on a job site.
