Add a second surface-mounted fixture position from an existing 4-inch junction box without cutting the wall or soffit for another recessed box. PIGGYBACK is a slim alternative to an industrial-looking surface conduit installation—for example, keeping a porch light at the original box while adding a camera farther along the same wall.

🌟 WHEN TO USE IT

  • Adds a second fixture location while leaving the original junction-box position available.
  • Works on wall or soffit installations.
  • Choose a nominal 8-, 16-, or 24-inch center-to-center offset in white or black.

📐 POSITIONING & ADJUSTMENT

  • The hole array on the primary junction-box adapter allows the assembly to leave the original box at multiple angles.
  • The selected 8-, 16-, or 24-inch length is measured center to center between the junction boxes.
  • The adjustable overlap in the printed center cover can add up to 1.5 inches of reach—for example, to align the secondary box with a stud.

🔩 MOUNTING & WIRE ROUTING

  • Original-box side fits a 4-inch junction box with 3.5-inch screw spacing.
  • Secondary fixture side accepts the fixture's own crossbar.
  • Lamp pipe connects the two printed boxes and keeps the wires isolated and protected.

📦 INCLUDED

  • 1 primary printed junction-box adapter
  • 1 secondary printed junction-box adapter
  • Extension wires
  • 2 terminal blocks
  • 2 mounting screws
  • 1 round gasket
  • Length-matched lamp pipe
  • 2 pipe covers
  • Couplings as required by the selected length; the 8-inch version uses no pipe coupling

🛠️ INSTALLATION NOTES

  • The included gasket is intended for the joint between the original junction box and the primary PIGGYBACK adapter, but placement can be adjusted for the installation.
  • Use the fixture's own gasket or seal at the secondary fixture-side joint.
  • Turn off power and follow the fixture manufacturer's instructions and applicable electrical requirements.
