What tools do I need for duct entry?

Troubleshooting
Chamber is not level after stacking
Ensure the base foundation (Type 1 or concrete) is perfectly leveled before placing the first section.
Duct entry point does not align with existing ducting
Use the integrated drilling guides to re-evaluate placement; if necessary, use a larger hole saw or adapter to accommodate misaligned ducts.
Difficulty stacking sections
Check the perimeter of each section for debris or damaged locking mechanisms; ensure they are clean before pressing into place.

Setup, Compatibility & Care
- Preparation: Prepare the trench floor with a clean, level surface of Type 1 material or concrete. Ensure the area is cleared of debris.
- Stacking: Place the first section and ensure it is level. Add subsequent sections until the final chamber depth is achieved.
- Ducting: Mark the required entry points using the integrated guides. Use a professional-grade holesaw to cut the openings.
- Completion: Once the structure is set, install necessary accessories such as cable management racks or steps (sold separately) before sealing with an approved cover.
- Maintenance: Regularly inspect the chamber interior for sediment buildup or obstruction. Ensure the cover is properly secured to prevent unauthorized access and ingress of surface water.
