Metal Concrete Back-Up Box ...

$15.96

Product details

The metal concrete back-up box (SKU 515M) is purpose-designed for concrete and block-wall central vacuum installs. Self-contained and made of aluminum, the box creates a protected wall cavity for the low-voltage wiring connections that sit behind the inlet valve. Pour concrete right around it; the interior stays fully protected.

In commercial applications it does double duty: it can house an externally mounted inlet valve where the piping runs exposed outside the wall.

  • Material: aluminum, self-contained
  • Connector: 2-inch inner diameter female pipe connector
  • Wiring: knock-out provided for low-voltage connections
  • Compatibility: receiving screw pattern matches universal-size inlet valves
  • Includes: plaster cover

For poured-concrete, block, and commercial exposed-pipe installs, SKU 515M is the purpose-built solution.
