Buying Guide
What is a poke-through floor box?
A poke-through floor box is a recessed device installed through a floor to bring power and data connections to a raised or finished surface. It provides a protected, accessible outlet or connector location while maintaining floor aesthetics.
Key considerations for choosing
- Floor material and thickness: Some units are specifically designed for wood floors, concrete, or tile, and have different core hole requirements.
- Number of outlets and modules: Decide if you need two-gang capacity, single-gang, or multi-service inserts for data and power.
- Fire rating: For commercial or code-sensitive environments, a fire-rated poke-through helps meet safety requirements.
- Installation method: Some models are two-piece with self-leveling features, while others are one-piece or require a junction box.
- Accessibility and maintenance: Consider whether you need easy removal for inspections or service.
- Future-proofing: Look for products that accept additional inserts or covers so you can upgrade without replacing the unit.
Installation practicality and safety
- Ensure the floor core hole is sized per the device specification and use proper sealants to prevent moisture ingress.
- Check for fire-stop requirements around the box, especially in reinforced concrete floors.
- Plan for cable routing and device height to align with furniture, desks, or seating areas.
