Octagonal aluminium back box · standard flange · for in-grade, wall, ceiling and stair installations · MP Lighting EBX-OCT1-CSMA
What this product is for
This octagonal aluminium back box is used as a rough-in housing for compatible MP Lighting recessed and in-grade luminaires and mounting kits. It provides the enclosure and mounting interface needed before the finished fixture is installed.
Use for
Use for ground, ceiling, wall and stair installations where the fixture schedule calls for MP Lighting OCT1 C-flange back box compatibility. It is suitable for wet, damp and dry locations.
Avoid for
Avoid using this back box where a different flange style, paving-stone flange, pipe version, or non-compatible fixture family is required. Confirm fixture and mounting kit compatibility before ordering.
Best for
Best for landscape and architectural lighting projects that need a manufacturer-matched rough-in component for in-grade or recessed installations. It is a practical choice when the box must be set during concrete, masonry or finish-stage coordination.
Installed in
Typically installed in grade, walls, ceilings and stair risers. The comparison sheets also indicate rebar-supported installation provisions, with a rebar hole sized at approximately 9/16 in (14 mm) and recommended rebar size of approximately 1/2 in / 10M, depending on the installation method and site conditions.
Why this product exists
This product allows the rough-in work to be completed before the luminaire is fitted, helping coordinate concrete, hardscape and finish trades. For many in-grade and recessed lighting jobs, using the correct manufacturer back box helps maintain fit, alignment and service access.
