This Smooth mounting block provides a robust foundation for electrical disconnect switches on residential and commercial installations. Engineered to bridge gaps between exterior s iding and electrical equipment, it creates the solid backing required by electrical codes for air conditioner disconnects, heat pump switches, and similar outdoor units. The block protects vulnerable fiber cement lap siding—from vibration, moisture infiltration, and fastener-related stress while establishing a level mounting surface on uneven walls. Its durable construction ensures secure anchoring of electrical boxes to structural support, meeting safety standards and extending the lifespan of both your siding and electrical components.
