CDB1 Concrete Deck Box
Three-piece pre-pour mounting system that embeds FLEX SLS module locations directly in concrete — flush, sealed, and ready for fixture install on pour day.
Lighting locations cast directly into the slab
The CDB1 ships in three components — a top plate, a chamber body, and a bottom mounting plate. The full assembly drops into formwork before the pour, locking the FLEX SLS bus path into the deck. After cure, top plate comes off, modules drop in, and the FLEX SLS 27.5VDC bus line is routed through the embedded chamber. No coring, no surface conduit, no patching.
- ✓ Three-piece pre-pour kit (top + chamber + bottom plate)
- ✓ Accepts FM2A, FM10A, and FM30A FLEX SLS modules
- ✓ Embedded directly during concrete pour
- ✓ Class 2 / 27.5VDC operation — no lock-out / tag-out
- ✓ Speeds rough-in for the electrical crew
Pour-day install workflow
CDB1 changes lighting from a finish-out trade to a structural pre-pour activity. The benefit shows up downstream when the rest of the build accelerates.
Layout
CDB1 boxes laid out per FLEX SLS plan — spacing matches FM module pattern.
Pour
Pre-pour assembly tied to rebar, concrete flows around the chamber. Top plate flush with finished slab.
Bus line
Once cured, top plate lifts off, 27.5VDC bus line is fed through the chamber and tied to neighbors.
Modules drop in
FM2A / FM10A / FM30A modules click into place via T-Connector. Slab finished, lighting live.
CDB1 is part of the FLEX SLS 3.0 system
