3/4" SNAP IN BLANK

3/4" SNAP-IN BLANK (Product Description)

A 3/4-inch snap-in blank is a knockout plug used to close unused 3/4" openings in electrical boxes or enclosures.

Product Description

This fitting is a non-metallic or steel snap-in knockout seal designed to fill and cover unused 3/4" conduit knockouts in junction boxes, panels, and enclosures.

It installs by simply pressing (“snapping”) into the knockout hole, securing itself without tools. Once installed, it prevents:

• Dust and debris entry
• Accidental contact with energized parts
• Air/moisture infiltration (depending on type)

These are commonly used in electrical panels, junction boxes, and metal or plastic enclosures where a knockout was not used for wiring.

Examples include steel snap-in knockout blanks such as the Appleton S-75 / Crouse-Hinds 336 series.
