Designed to provide a solid base for HVAC units, generators, and other outdoor equipment, these pads are made from high-strength plastic materials engineered to resist cracking, corrosion, and environmental wear — all at just a fraction of the weight. At only 5 lbs, these pads are easy to transport and install while still offering reliable support in residential or light commercial applications. Key Features: Lightweight Plastic Construction: Weighing just 5 lbs, these plastic mounting pads are a breeze to handle and install compared to heavy 85 lb concrete slabs, without compromising structural integrity for most standard equipment needs. Standard Dimensions for Versatile Use: Each pad measures 18 inches wide by 40 inches long and 4 inches thick, making them ideal for a wide range of outdoor installations, especially HVAC systems and similar equipment. Weather-Resistant & Long-Lasting: These plastic pads are built to withstand moisture, UV exposure, and temperature fluctuations without degrading, cracking, or warping over time. Fast, Easy Installation: Lightweight and low-maintenance, these pads can be installed quickly on a level surface — no concrete mixing, heavy lifting, or curing time required. Reliable Support for Outdoor Equipment: While lighter in weight, these pads are engineered for stable load distribution across common outdoor installations, helping prevent equipment sinking or shifting on softer ground surfaces. Typical Applications: HVAC Unit Mounting Generators and Outdoor Electrical Equipment Water Heaters or Pumps Light Machinery or Utility Enclosures Why Choose Plastic Mounting Pads Over Concrete? Save time, labor, and back pain. Plastic mounting pads provide a clean, professional base without the hassle and weight of concrete.
