Product Description Our Impact Pulsating Sprinkler with 16–30" Adjustable Aluminum Sprinkler Riser is engineered to deliver powerful, consistent irrigation for lawns, gardens, and large yard areas. Unlike ordinary plastic lawn sprinklers that crack under pressure or get blocked by growing plants, this heavy duty metal impact sprinkler features a telescoping riser extension that elevates the spray above shrubs, raised beds, and tall grass. Designed for durability, stability, and expandability, it provides efficient watering season after season. Features: 1. Adjustable Sprinkler Riser Extension – Telescopes from 16–30" to eliminate blocked sprinklers and ensure even coverage over vegetation. 2. Heavy Duty Metal Construction – Made from high quality aluminum and zinc alloy with stainless steel central pin for long lasting outdoor performance. 3. Full & Partial Circle Coverage – Adjust from 360° full rotation to 20°–340° arc patterns for customized lawn and garden irrigation. 4. Stable Spike Base Design – Simply step the zinc spike into soil or turf to secure the sprinkler firmly in place during watering. 5. Expand Irrigation System – Flow through connector allows multiple sprinklers to be linked in series to cover large yard areas with one faucet connection.
