Orbit CB-B 4" Octagonal Concrete Box Blank Cover

The Orbit CB-B 4" Octagonal Concrete Box Blank Cover is a flat, solid closure plate designed to cap and seal 4" octagonal concrete boxes used in underground and in-slab electrical installations. Sized for a standard 4" octagonal concrete ring, this blank cover provides a smooth, unbroken surface that protects the box interior from concrete intrusion, debris, and moisture during and after the pour. It is a straightforward, purpose-built accessory for electricians and contractors who need a dependable way to close out a concrete box location that does not require an immediate device, fixture, or conduit termination.

Key Features

  • Trade Size: Engineered to fit a 4" octagonal concrete box, matching the standard concrete ring diameter for a proper, flush seat.
  • Blank, Flat Design: A solid, uninterrupted cover plate with no knockouts or openings, ideal for sealing a box location that is not yet in service or does not require wiring access.
  • Octagonal Configuration: Matches the octagonal profile of the companion concrete box/ring for a consistent, aligned fit at grade or slab level.
  • Concrete-Compatible Build: Constructed to hold up to the demands of in-slab and underground concrete box applications, helping keep the enclosure clean and ready for future use.
  • Simple Field Installation: Designed to seat directly onto the 4" octagonal concrete box for quick placement by electrical and concrete crews alike.
