The SLH-5A from ARANI is a four-gang airtight electrical box constructed from high-impact, flame-retardant plastic that meets rigorous safety and performance requirements. Its generous interior volume accommodates multiple conductors and devices, making it ideal for complex switch configurations and multi-device wall plates. The box is cUL/CSA approved, ensuring full compliance with Canadian electrical codes and inspection standards.

The airtight sealed design is a critical feature for modern building envelopes, helping meet or exceed energy code requirements related to air barrier continuity. By minimizing air infiltration at electrical penetration points, this box supports improved thermal management within wall cavities, reducing heat loss in winter and heat gain in summer. This contributes to measurable energy savings compared to traditional non-sealed electrical boxes.

Installation is simplified through integrated mounting features and clearly marked knockout openings that accept standard cable connectors. The durable plastic body resists corrosion and does not require grounding of the box itself, streamlining the wiring process. Its robust construction withstands the mechanical stresses of both new construction and renovation environments without cracking or warping.

For homeowners and contractors seeking reliable, code-compliant electrical rough-in components, this box delivers consistent quality backed by Canadian safety certifications. It is compatible with standard four-gang cover plates and devices, ensuring seamless integration with your chosen switches, dimmers, and receptacles. Choosing certified, airtight-rated components like this is an investment in both the safety and long-term energy performance of your home.
