The ARANI SLH-3A features a rugged thermoplastic construction that resists impact, moisture, and the wear associated with long-term installation behind finished walls. The material is self-extinguishing and designed to withstand the thermal demands of modern electrical systems, ensuring that the box maintains its structural integrity over decades of service in residential environments.

This three-gang box is engineered with an airtight design that meets increasingly stringent Canadian building envelope requirements. By minimizing air infiltration at electrical penetration points, it supports improved energy efficiency and helps homeowners comply with updated building codes that emphasize reduced air leakage. This is particularly valuable in climate zones across Canada where thermal performance directly impacts utility costs.

The SLH-3A is cUL listed and approved for use in Canadian electrical installations, giving both homeowners and electricians confidence that it meets all applicable safety standards. Its generous internal volume accommodates multiple conductors and devices without overcrowding, supporting code-compliant wiring practices and reducing the risk of overheating or connection failure during operation.

Installation is straightforward thanks to integrated mounting features and clearly marked knockout openings that accept standard cable connectors. The box is compatible with a wide range of NMD90 cable sizes and supports secure fastening to wood or steel studs. Whether you're roughing in a new build or upgrading an existing wall during a renovation, the ARANI SLH-3A provides a professional-grade solution that simplifies the process and delivers lasting reliability.
