Overview

The Mlhezy 20PCS Seal Electrical Box Knockout set is designed to tidy up unused holes in electrical boxes with minimal effort. The kit includes 20 durable round seals in two handy sizes, ready to seal off empty knockouts and help maintain a clean, safe electrical interior as you work on wiring projects or renovations.

Two sizes for flexible sealing

Two practical sizes cover common knockout openings. Each plug sits flush to reduce snagging and ensure a neat appearance.

  • Size 1 fits 1/2-inch holes
  • Size 2 fits 3/4-inch holes
  • Ten seals of each size keep spares on hand

Durable, reusable construction

Nickel-plated carbon steel provides a durable, smooth surface that resists wear. The seals are removable and reusable, supporting ongoing maintenance without needing new parts for every project.

Easy installation and broad utility

Designed for quick, tool-free installation, you simply press the plug into the punching hole until it sits flush. The simple fit helps you save time during setup and remodels, whether at home or at a workspace.

Versatile for home and business use

Ideal for residential wiring closets, small offices, workshops, or commercial fit-outs, these seals offer a practical solution for sealing unused knockouts, contributing to a cleaner look and safer boxes.

Value in a single pack

The 20-piece pack ensures you have spares ready for routine tasks, making it easier to maintain consistency across projects and reduce trips to the store.
