Knock-out Seals, Pre-galvanized 3/4"

Product Overview

Knock-out Seals, Pre-galvanized 3/4", are designed to seal unused knockout holes in electrical panels, junction boxes, and enclosures. These seals are made of pre-galvanized steel, which provides excellent corrosion resistance, durability, and protection from the elements. The 3/4" size is ideal for standard knockout openings, making this seal suitable for a wide range of electrical installations. These seals are easy to install, offer superior sealing properties, and are commonly used in residential, commercial, and industrial electrical applications.

Product Description

The Knock-out Seals 3/4", made from pre-galvanized steel, are designed to be used in electrical enclosures to close off unused knockout holes. Knockouts are pre-punched holes in electrical boxes that allow for the installation of conduit or wiring systems. When these holes are not in use, they must be sealed to prevent the ingress of dust, moisture, and debris, which can compromise the electrical system’s safety and functionality.

These seals are installed by either threading them into place or pressing them into the knockout hole, depending on the design of the seal. The 3/4" size is perfect for smaller knockouts, commonly found in smaller electrical boxes or enclosures. The pre-galvanized steel finish ensures that the seals are highly resistant to corrosion and rust, making them suitable for a variety of environmental conditions.
