A slab on grade floor box opening features a depressed concrete trench reinforced with continuous number five bars at mid-height and standard ninety-degree hooks at the corners. The slab reinforcement matches the main slab thickness and extends into the thickened edge of the pit. Six-inch dimensions establish the perimeter clearance around the depressed trough. Access floor tiles sit flush across the top opening as coordinated with architectural finishes.
