Arlington SP364 Sill Plate 1.5 Inches

Product Description

The ARLINGTON SP364 is a 1.5-inch sill plate fitting designed to provide a clean, weatherproof transition point where conduit or cable enters a structure through a foundation sill or exterior wall. The plate seals around the entry point to block moisture, air infiltration, and pests. Electricians and low-voltage installers use this type of fitting on residential and light commercial projects where cable or conduit passes through wood framing members at the sill level. It is a straightforward, code-friendly solution for protecting penetrations at the building envelope.

This sill plate is suited for installations where conduit or cable must pass through a wood sill plate, rim joist, or similar framing member. Common applications include service entrances, feeders, and low-voltage cable runs entering a structure at or near the foundation. The 1.5-inch size accommodates standard trade-size conduit or cable bundles at that nominal diameter.

• 1.5-inch nominal opening fits standard conduit or cable at that trade size

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage technician. De-energize all circuits before feeding cable or conduit through the fitting.
