Non-Metallic Adjustable SliderBox™
Adjustable Depth Without Having to Remove or Relocate Screws
AMP-SB-1
What's special about this electrical box?
- Innovative slider plate allows the wall box to adjust to varying depths for applications in which additional material such as tile or soundproofing devices are being added to the surface
- Features a non-slip pad to provide the box and slider assembly a 50 lbs pull strength, to hold securely during power cord pull out
- Smoothly adjusts for wall substrates from 1/2" to 1 3/8" thick to meet building codes and regulations

Building codes require your electrical boxes to sit flush against the surface of the wall or ceiling, which means that if you are planning on applying a decorative finish such as ceramic tile on top of your drywall, your electrical box will be recessed and not pass inspection. With the Sliderbox™, simply loosen the screws and pull the box forward, instead of removing and relocating the entire junction box.
