3. Align blank with knockout opening from inside of enclosure
4. Press firmly until snap-in mechanism engages with audible click
5. Verify secure installation by gently tugging on blank
6. Check that blank sits flush with enclosure surface

Applications

Perfect for:

• Electrical Panel Boxes - Sealing unused knockouts in distribution panels and load centers
• Motor Control Centers - Maintaining enclosure integrity in industrial control applications
• Junction Boxes - Closing unused openings in pull boxes and junction enclosures
• Switchgear Enclosures - Professional sealing of unused conduit entries
• Commercial Buildings - Office buildings, retail spaces, and institutional facilities
• Industrial Facilities - Manufacturing plants, processing facilities, and warehouses
• Maintenance Applications - Retrofit installations and system modifications
• New Construction - Initial installation with future expansion planning

Knockout Sealing System Benefits

Proper knockout sealing is essential for maintaining electrical enclosure integrity and code compliance. Unsealed knockouts create pathways for moisture, dust, and contaminants that can cause equipment failure, safety hazards, and code violations. The snap-in design provides superior retention compared to push-in plugs while offering easier installation than threaded closures.

Why Choose Steel Construction?

Steel knockout blanks offer superior durability and fire resistance compared to plastic alternatives. The material provides excellent impact resistance and maintains dimensional stability over time. Steel construction ensures long-term reliability in demanding commercial and industrial environments while meeting stringent electrical code requirements for enclosure protection.
